  • HELMET
    A helmet should be worn if trees to be cleared are higher than 2 metres.

  • EAR PROTECTION
    Ear protection offering sufficient dampening effect should be used.

  • EYE PROTECTION
    Blows from branches or objects thrown by the rotating cutting equipment can damage the eyes.

  • GLOVES
    Gloves should be worn when necessary, e.g., when assembling cutting equipment.

  • BOOTS
    Use anti-slip and stable boots.

  • CLOTHING
    Wear clothes made of a strong fabric and avoid loose clothing that can catch on shrubs and branches. Always wear heavy-duty long pants. Do not wear jewellery, shorts, sandals or go barefoot. Secure hair so it is above shoulder level.

  • FIRST AID KIT
    A first aid kit should be carried by operators of clearing saws, brushcutters or trimmers.

The machine‘s safety equipment
This section describes the machine‘s safety equipment, its function and how checks and maintenance are carried out to ensure that it operates correctly. (See the chapter “What is what“ to locate where this equipment is positioned on your machine.)

WARNING!
Never use a machine with defective safety equipment. Follow the control, maintenance and service instructions described in this section.

Throttle trigger lock
The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (A) is pressed into the handle (= when you hold the handle) the throttle (B) is released. When the grip on the handle is released the throttle and the throttle trigger lock return to their original positions. This takes place via two independent return spring systems. This means that the throttle is automatically locked in its “idling“ position.

Stop switch
The stop switch should be used to stop the engine.Husqvarna-227R-Brush-
Cutter-FIG- \(4\)

Cutting attachment guard
This guard is intended to prevent objects from being thrown towards the operator and to protect the operator from unintentionel contact with the cutting attachment.

WARNING!

  • Do not attach any blade to the unit without proper installation of all required parts. Failure to use the proper parts can cause the blade to fly off and seriously injure the operator and/or bystanders.
  • Under no circumstances may the cutting equipment be used without an approved guard fitted. See the chapter “Technical data”. If the wrong guard or a defective guard is fitted this can cause serious personal injury.

Anti-vibration system

  • Your machine is equipped with an anti-vibration system that has been designed to give as vibration-free and comfortable usage as possible.
  • The use of incorrectly wound cord or blunt, incorrect cutting equipment (incorrect type or incorrectly sharpened, see section “Filing the blade”) increases the level of vibration.
  • The machine’s vibration damping system reduces the transfer of vibrations between the engine unit/cutting equipment and the machine’s handle unit.

WARNING!
Over exposure to vibrations can result in blood-vessel or nerve injury to persons suffering with blood circulation problems. Seek medical attention if you experience physical symptoms that can be related to over exposure to vibrations. Examples of such symptoms are “numbness“, lack of feeling, “tickling“, “pricking“, “pain“, lack of or a reduction in normal strength, changes in the colour of the skin or its surfaces. These symptoms normally appear in the fingers, hands or wrists.

Quick-release
There is an easily accessible, quick-release catch fitted to the chest as a safety precaution in the event of a fire in the engine or for any other situation that requires you to free yourself from the machine and harness. See the section “Adjusting the harness and clearing saw“.

Muffler
The muffler is designed to give the lowest possible noise level and to direct the engine‘s exhaust fumes away from the operator. Muffler fitted with catalytic converter is also designed to reduce harmful exhaust components.
In countries that have a warm and dry climate the risk of fire is obvious. We have therefore fitted certain mufflers with a spark arrest screen. Make sure that your muffler is fitted with this kind of screen.
The instructions for checking, maintaining and servicing the muffler must be followed. (See the section “Control, maintenance and service of the machine‘s safety equipment“.)

WARNING!
Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!

WARNING!
Bear in mind that exhaust fumes:

  • carbon monoxide, which can cause carbon monoxide poisoning. Therefore never start or run the machine indoors.
  • are hot and can contain sparks that can cause fires. Never start the machine indoors or close to inflammable material.

Cutting equipment

  1. Clearing blades are intended for cutting wood.
  2. Grass blades are intended for brush cutting.
  3. The trimmer head is intended for trimming grass.

Locking nut
A locking nut is used to secure some types of cutting equipment on the output shaft.

Control, maintenance and service of the machine‘s safety equipment

  • All service and repairs to the machine require special training.
  • This applies especially to the machine‘s safety equipment. If the machine does not meet any of the controls listed below you should contact your service workshop.
  • The purchase of one of our products guarantees that professional repair and servicing will be carried out on it. If the point of purchase is not one of our servicing dealers, please ask for details of the closest service workshop.

Throttle trigger lockHusqvarna-227R-Brush-Cutter-FIG-
\(10\)

  • Check that the throttle is locked in the “idling position“ when the throttle trigger lock is in its original position.

  • Press in the throttle trigger lock and make sure it returns to its original position when released.

  • Ensure that the throttle and throttle trigger lock move easily and that their return spring systems function.
    The throttle trigger lock is designed to prevent the throttle from accidentally being engaged. When the trigger lock (A) is pressed into the handle (= when you hold the handle) the throttle (B) is released. When the grip on the handle is released the throttle and the throttle trigger lock return to their original positions. This takes place via two independent return spring systems. This means that the throttle is automatically locked in its “idling“ position.

  • See section “Start”. Start the machine and apply full throttle. Release the throttle and check that the cutting equipment stops and remains at a standstill. If the cutting equipment rotates with the throttle in the idling position then the carburettor‘s idling setting must be checked. See chapter “Maintenance“.Husqvarna-227R-Brush-Cutter-FIG- \(11\)

Stop switch

  • Start the engine and make sure that the engine stops when the stop switch is moved to the stop position.

Cutting attachment guard

  • Check that the guard is undamaged and not cracked.
  • Replace the guard if it has been exposed to impact or is cracked.
  • Always use the prescribed blade an guard combination, see chapter “Technical data”.

Vibration damping system

  • Check the vibration-damping element regularly for material cracks and distortion.
  • Check that the vibration-damping element is undamaged and securely attached.

Muffler

  1. Never use a machine that has a defective muffler.
  2. Check regularly that the muffler is secure.
  3. If your muffler is fitted with a spark arrest screen then it should be cleaned regularly. A blocked screen leads to the engine overheating with serious damage as a result. Never use a muffler with a defective spark arrest screen.

Cutting equipment
This section describes how through correct maintenance and through using the right type of cutting equipment you can:

  • Reduce the machine‘s tendency to kickback
  • Obtain maximum cutting capacity.
  • Increase the service life of the cutting equipment.

Four basic rules:

  1. Only use the cutting and guard equipment we recommend! See chapter “Technical data“.
  2. Keep the blade‘s teeth well and correctly sharpened! Follow our instructions and use the recommended filing gauge. An incorrectly sharpened or damaged blade increases the risk of an accident.
  3. Keep the correct setting. Follow our instructions and use the recommended setting tool. An incorrectly set blade increases the risk of jamming and kickback.
  4. Check the cutting equipment with regard to damage and crack formation. Damaged cutting equipment should always be replaced.

Quick-release
Check that the harness straps are correctly positioned. When the harness and machine are adjusted, check the harness‘ safety release catch to ensure it works correctlyHusqvarna-227R-Brush-Cutter-FIG- \(17\)

Locking nutHusqvarna-227R-Brush-Cutter-FIG- \(18\)

  • Protect your hand from injury when assembling, use the blade guard as protection when tightening with a socket spanner. Tighten the nut by turning against the direction of rotation. Loosen the nut by turning in the direction of rotation. (NOTE! the nut has a left-hand thread).
  • Tighten the nut using a socket spanner, 35 – 50 Nm (3.5 – 5 kpm).
    NOTE!
    The locking nut‘s nylon lock must not be so worn that it can be turned by hand. The lock shall hold at least 1.5 Nm. The nut should be replaced after it has been put on approx. 10 times

WARNING!
Never use a machine with defective safety equipment. The safety equipment should be maintained as described in this section. If your machine does not meet any of these controls you should contact your service workshop.

Cutting equipment

IMPORTANT INFORMATION

  • The section describes how through correct maintenance and through using the right type of cutting equipment you can reduce the machine‘s tendency to kickback, obtain maximum clearing capacity and increase the service life of the cutting equipment.
  • Only use the cutting and guard equipment we recommend! See chapter “Technical data“.
  • Refer to the instructions for the cutting equipment for the correct winding of the cord and for the selection of the right cord diameter.
  • Keep the blade’s teeth well and correctly sharpened! Follow our recommendations. Also refer to the instructions on the blade packaging.
  • Maintain the correct setting. Follow our instructions and use the recommended filing gauge

WARNING!
Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback

Sharpening the clearing bladeHusqvarna-227R-Brush-Cutter-FIG-
\(19\)

  • See the cutting equipment’s packaging for correct filing instructions.
  • A correctly sharpened blade is a prerequisite for working efficiently and to avoid unnecessary wear to the blade and clearing saw.
  • Make sure that the blade is well-supported when you use the file. Use a 5,5 mm round file with a file holder.
  • The sharpening angle is 15°. Every other tooth is sharpened to the right and the intermediate tooth to the left. When the blade has been heavily pitted by stones the upper side of the teeth can, in exceptional cases, need to be dressed using a flat file. In such cases this takes place before sharpening with the round file. Dressing the top side must be carried out equally for all teeth.
  • Adjust the setting. This should be 1 mm.

Sharpening the grass blade

  • See the cutting equipment’s packaging for correct filing instructions.
  • The blades are sharpened using a single cut flat file.
  • Sharpen all edges equally to maintain the balance of the blade.

Trimmer head

  • Only use a trimmer head and trimmer cord that is recommended. These have been tested by the manufacturer to suit a particular engine size. This is especially important when a fully automatic trimmer head is used. Only use the cutting equipment we recommend! See chapter “Technical data“.
  • Generally smaller machines require a small trimmer head and vice versa. This is because when clearing using a cord the engine must throw out the cord radially from the trimmer head and also meet resistance from the grass being cleared.
  • The length of the cord is also important. A longer cord requires greater engine power than a shorter cord of the same diameter.
  • Make sure the knife positioned on the trimmer guard is intact. This is used to cut the cord to the correct length.
  • To increase the life of the cord it can be soaked in water for a few days. This will make the line tougher and it will keep longer.

IMPORTANT INFORMATION
Always ensure the trimmer cord is wound tightly and evenly around the drum, otherwise harmful vibrations will occur.

WARNING!

  • Always stop the engine before starting work on any part of the cutting equipment.
  • This continues to rotate even after the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it.

General safety instructions

  • The machine is only designed for trimming grass, brush cutting, and/or forestry clearing.
  • The only accessories to be used with the engine unit as a drive source are the cutting units we recommend in the chapter “Technical data“.
  • Never use the machine if you are tired if you have consumed alcohol, or if you are taking medicines that can affect your sight, your judgment or the control of your body.
  • Use personal protective equipment. See the section “Personal protective equipment“.
  • Never use a machine that has been modified so that it no longer corresponds with the original design.
  • Never use a faulty machine. Follow the maintenance, control, and service instructions in this Operator‘s Manual. Some maintenance and service actions should be carried out by trained and qualified specialists. See the chapter “Maintenance“.
  • All covers and guards must be fitted before starting the machine. Check that the spark plug cap and HT lead are not damaged, otherwise you could get an electric shock.
  • While working, the machine operator shall ensure that no persons or animals come closer than 15 metres (50 feet). When several operators are working in the same area the safety distance should be at least double tree length, however, at least 15 metres (50 feet).

WARNING!
Faulty cutting equipment or an incorrectly sharpened blade increases the risk of incidents

Start

When the engine starts with the choke lever in the choke or starter throttle position the cutting equipment starts to rotate immediately

  • The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury.
  • Never start the machine indoors. Bear in mind the dangers of inhaling the engine‘s exhaust fumes.
  • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.
  • Place the machine on the ground, and ensure the cutting equipment runs free of twigs and stones. Push the machine body towards the ground using your left hand. (NOTE! Not with your foot). Grip the starter handle with your right hand and pull the starter cord.

Fuel safetyHusqvarna-227R-Brush-Cutter-FIG- \(23\)

  • Always use a fuel container with an anti-spill valve.
  • Never fill the machine while the engine is running. Always stop the engine and let it cool for a few minutes before refueling.
  • Provide good ventilation when filling or mixing fuel (petrol and 2-stroke oil).
  • Move the machine at least 3 m from the filling position before starting.
  • Never start the machine:
    • If you have spilt fuel on it. Wipe up all spillage.
    • If you have spilt fuel on yourself or your clothes. Change your clothes.
    • If there is a fuel leak.
      Make regular checks for leakage from the fuel cap and the fuel supply pipes.

Transport and storage

  • Store and transport the machine and fuel so that any leakage or fumes do not risk coming into contact with sparks or naked flames. For example, electric machines, electric motors, electrical switches/power switches, heaters or the like.
  • When storing and transporting fuel approved containers intended for this purpose must be used.
  • When storing the machine for long periods the fuel tank must be emptied. Contact your local petrol station to find out how to dispose of excess fuel.
  • Always keep the transport guard attached when transporting and storing the machine.

WARNING!
Exercise great care when handling fuel. Bear in mind the risk of fire, explosions and inhaling fumes.

IMPORTANT INFORMATION

  • This section takes up the basic safety precautions for working with the clearing saw and trimmer.
  • If you encounter a situation where you are uncertain how to proceed you should ask an expert. Contact your dealer or your service workshop.
  • Avoid all usage that you consider to be beyond your capability.
  • You must understand the difference between clearing, brush cutting and grass trimming before using the machine.

Basic safety precautions

  1. Observe your surroundings:
  2. To ensure that people, animals or other things cannot affect your control of the machine.
  3. To ensure that the above-mentioned do not come into contact with the cutting equipment or objects that can be thrown by the cutting equipment.
  4. NOTE! Never use a machine without the possibility of calling for help in the event of an accident.
  5. Avoid usage in unfavorable weather conditions. For example, thick fog, heavy rain, strong winds or extreme cold, etc. To work in bad weather conditions is tiring and can create dangerous circumstances, e.g. slippery surfaces, affect a tree‘s direction of fall, etc.
  6. Make sure you can walk and stand safely. Look out for any obstacles with unexpected movement (roots, stones, branches, pits, ditches, etc.). Take great care when working on sloping ground.
  7. Take great care when cutting a tree that is subject to tension. A tree that is under tension can spring back to its original position both before and after being cut. Incorrect positioning on your behalf or when positioning the cut can result in the tree hitting you or the machine so that you lose control. Both situations can cause serious personal injury.Husqvarna-227R-Brush-Cutter-FIG- \(25\)
  8. The engine should be switched off before moving. When moving over longer distances and transporting the transport guard should be used.
  9. Never put the machine down with the engine running unless you have good sight of it.

Adjusting the harness and clearing saw

WARNING! When working with the clearing saw it should always be hooked in the harness. If this is not done, you cannot control the clearing saw safely and this can result in injury to yourself or someone else. Never use a harness with a defective quick release catch.

Safety release

  • On the front is an easily accessible, quick-release catch.
  • Use this if the engine should catch fire or in any other emergency when you quickly need to take off the harness and machine.
  • Certain harnesses also have a quick-release fitted to the support hook. Push down the red release lever to release the machine from the harness.

Even load on the shoulders
A well-adjusted harness and clearing saw significantly facilitates working. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across the shoulders.

Correct heightHusqvarna-227R-Brush-Cutter-FIG-
\(27\)

  1. Forestry clearing
    Adjust the carrier strap so that the suspension hook comes approximately 10 cm under the hip. The blade should be angled forward a little.

  2. Grass clearing
    The suspension hook should hang approximately 20 cm under the hip so that the blade is parallel to the ground.

Correct balance

  1. Forestry clearing
    Move the suspension eye forward or backward. If the blade is balanced 10- 20 cm above the ground it is easier to avoid stones.

  2. Grass clearing
    Let the blade balance at a comfortable clearing height, i.e. close to the ground.

Basic clearing techniques
Always drop to idling speed after each working operation. Longer periods running at full throttle without loading the engine (that is without resistance, which the engine feels from the cutting equipment when trimming) can lead to serious engine damage

Designations

  • Forestry clearing is a general term for cutting small trees where each stem is cut individually. A saw blade is used.
  • Brush cutting is a general term for clearing grass. Grass blades are used for this purpose.
  • Grass trimming is a general term for light clearing, e.g. around edges or trees. A trimmer head or plastic blade is used.

WARNING!
Sometimes branches, grass or wood can get caught between the guard and cutting equipment. Always stop the engine when cleaning.

Clearing‘s ABC

  • A. Always use the correct equipment.
  • B. Always have well-adjusted equipment.
  • C. Follow the safety instructions.
  • D. Organise the work well.
  • E. Always use full throttle when applying the blade.
  • F. Always use a sharp blade.
  • G. Avoid stones.
  • H. Guide the direction of fall (use the wind).

WARNING!
Avoid cutting in the cutting region between 12 and 3 o‘clock on the blade. Kickback can occur due to the blade‘s rotation speed in this area of the blade when applied on thick stems.

Working methods

  • Before you start clearing, check the clearing area, its condition, slopes, if there are stones, pits, etc.
  • Thereafter start at the easiest end, and make a good start to the clearing.Husqvarna-227R-Brush-Cutter-FIG- \(29\)
  • Work systematically to and from and across the area. Each stroke should encompass a working area of 4-5 meters. This then utilizes the full working area of the machine in both directions and provides the operator with an easy and variable working area to work through.
  • The length of the pathway should be approx. 75 m. Move the fuelling station as work progresses.
  • On sloping ground, the pathway should run parallel to the slope. It is far easier to work along a slope than up and down a slope.
  • The pathway should be planned so that you avoid going over ditches or other obstacles. Also, adapt the pathway to the wind conditions so that the cleared stems fall on the part of the stand that has been cleared.

Forestry clearing using a saw blade

  • When applying the blade to heavier stems the risk of kickback increases. You should therefore avoid applying the blade on the cutting area between 12 and 3 o‘clock.
  • To fell to the left, the lower section of the tree should carry to the right. Angle the blade and move it with a resolute movement diagonally down to the right. At the same time press against the stem using the blade guard. Apply the blade on the area between 3-5 o‘clock. Use full throttle when applying the blade.
  • To fell to the right, the lower section of the tree should carry to the left. Angle the blade and move it with a resolute movement diagonally up to the left. Apply the blade on the area between 3 and 5 o‘clock so that the blade‘s direction of rotation carries the lower section of the tree to the left.
  • To fell a tree forwards the lower section of the tree should be drawn backwards. Draw the blade backwards with a quick and resolute movement.
  • Large stems must be cut from two sides. Determine in which direction the stem should fall. First apply the saw to the felling side. Then cut from the other side to fell the stem. The feed pressure should be applied with regard to the size of the stem‘s hardness. Small stems require more pressure, while large stems require less pressure.Husqvarna-227R-Brush-Cutter-FIG- \(34\)
  • If the stems are tightly packed adapt the through-speed with this in mind.
  • If the blade should jam in the stem, never jerk the machine free. If you do this the blade, angle gear, shaft or the handlebars can be damaged. Release the handlebars and grip the shaft with both hands and slowly pull the machine free.

Brush cutting using the saw bladeHusqvarna-227R-Brush-Cutter-FIG-
\(35\)

  • Thin stems and brush are mown down. Work by swinging the machine sideways.
  • Try to cut several stems in one movement.
  • With groups of hardwood stems, first clear around the group. Cut high on the stems around the outside of the group to avoid jamming. Now cut the stumps to the required height. Now try to come in with the blade and cut from the centre of the group. If it is still difficult to gain access, cut long stumps and let the stems fall down. This will reduce the risk of jamming.

Brush cutting using a grass blade

  • A blade is used for all types of high or thick grass.

  • The grass is cut down with a sideways, swinging movement, where the movement from right-to-left is the clearing stroke and the movement from left-to-right is the return stroke. Let the blade work on the left-hand side
    (between 8 and 12 o’clock).

  • If the blade is angled to the left when clearing the grass will collect in a line, which makes collection easier, e.g. when raking.

  • Try to work rhythmically. Stand firmly with your feet apart. Move forward after the return stroke and stand firmly again.

  • Let the support cup rest lightly against the ground. It is used to protect the blade from hitting the ground.

  • Reduce the risk of material wrapping around the blade by following these instructions:

    • Always work at full throttle.
    • Avoid the previously cut material during the return stroke.
  • Stop the engine and remove the brushcutter from the harness before you start to gather the cut material.

WARNING!
Neither the user of the tool or anyone else may attempt to remove the cut material while the engine is running or with the blade rotating as this can result in serious injury. Stop the engine and blade before you remove material that has wound around the blade as otherwise there is a risk of injury. The bevel gear unit can get hot during use and may remain so for a while afterwards. There is a risk of slight burns if you touch it.

WARNING!
Beware of thrown objects. Always wear eye protection. Never lean over the guard. Stones, rubbish etc. can be thrown up into the eyes resulting in blindness or other serious injury.
Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be outside the safety zone of 15 meters (50 feet). Stop the machine immediately if anyone approaches.

Grass clearing using the trimmer head and plastic knifesHusqvarna-227R-
Brush-Cutter-FIG- \(37\)

  • Hold the trimmer head just above the ground at an angle. It is the end of the cord that carries out the work. Let the cord work at its own pace. Do not press the cord into the area to be cut.
  • The cord can easily remove grass and weeds up against walls, fences, trees and borders, however, it can also damage sensitive bark on trees and bushes and damage fence posts.
  • Reduce the risk of damaging plants by shortening the cord to
    10- 12 cm and reducing the engine speed.

Clearing

  • The clearing technique removes all unwanted vegetation. Keep the trimmer head just above the ground and tilt it. Let the end of the cord strike the ground around trees, posts, statues and the like. NOTE! This technique increases the wear on the cord.
  • The cord wears quicker and must be fed forward more often when working against stones, brick, concrete, metal fences, etc. than when coming into contact with trees and wooden fences.
  • When trimming and clearing you should use less than full throttle so that the cord lasts longer and to reduce the wear on the trimmer head.

Trimming

  • The trimmer is ideal to cut grass that is difficult to reach using a normal lawn mower. Keep the cord parallel to the ground when cutting. Avoid pressing the trimmer head against the ground as this can ruin the lawn and damage the tool.
  • Do not allow the trimmer head to constantly come into contact with the ground during normal cutting procedures. Constant contact can cause damage and wear to the trimmer head.

Sweeping

  • The rotating cord‘s fanning effect can be used for quick and easy cleaning. Hold the cord parallel to and above the area to be swept and move the trimmer from side to side.
  • When cutting and sweeping you should use full throttle to obtain the best results.

WARNING!
Beware of thrown objects. Always wear eye protection. Never lean over the guard. Stones, rubbish etc. can be thrown up into the eyes resulting in blindness or other serious injury.
Keep unauthorised persons at a distance. Children, animals, onlookers and helpers should be outside the safety zone of 15 meters (50 feet). Stop the machine immediately if anyone approaches.

Assembly of the blade and trimmer head

It is extremely important that the disc drive’s/support flange’s guide engages correctly in the cutting equipment’s centre hole when assembling the cutting equipment. Cutting equipment assembled incorrectly can result in serious and/or fatal personal injury.

WARNING!
Do not attach any blade to the unit without proper installation of all required parts. Failure to use the proper parts can cause the blade to fly off and seriously injure the operator and/or bystanders.
Under no circumstances may the cutting equipment be used without an approved guard fitted. See the chapter “Technical data”. If the wrong guard or a defective guard is fitted this can cause serious personal injury.

IMPORTANT INFORMATION
The machine must be equipped with the correct handlebars, blade guard and harness if either a clearing blade or grass blade are to be used.

  • Press the handle towards the coupling.
  • Carefully twist the lower section out of the lock.
  • Hold both parts of the shaft and pull out the lower section from the coupling.

Adjusting the harness and clearing saw

WARNING!
When working with the clearing saw it should always be hooked in the harness. If this is not done, you cannot control the clearing saw safely and this can result in injury to yourself or someone else. Never use a harness with a defective quick release catch.

Quick release
On the front is an easily accessible, quick release catch. Use this if the engine should catch fire or in any other emergency situation when you quickly need to take off the harness and machine.

Even load on the shoulders
A well-adjusted harness and clearing saw significantly facilitates working. Adjust the harness for the best working position. Tension the side straps so that the weight is evenly distributed across the shoulders.

Correct height

  1. Forestry clearing Adjust the carrier strap so that the suspension hook comes approximately 10 cm under the hip. The blade should be angled forward a little.
  2. Grass clearing
    The suspension hook should hang approximately 20 cm under the hip so that the blade is parallel to the ground.

Correct balance

  1. Forestry clearing
    Move the suspension eye forward or backward. If the blade is balanced a 10-20 cm above the ground it is easier to avoid stones.

  2. Grass clearing
    Let the blade balance at a comfortable clearing height, i.e. close to the ground.

FUEL HANDLING

Fuel mixture
NOTE!
The machine is fitted with a two-stroke engine and must always be run on a mixture of gasoline and two-stroke oil. It is important to measure the quantity of oil accurately, to ensure the correct mixture ratio. Small discrepancies in the amount of oil have a great bearing on the proportions of the fuel mixture when mixing small amounts of fuel.

WARNING!
Always provide good ventilation when handling fuel.

Gasoline
NOTE!
Always use an oil-mixed quality gasoline (at least 87 octane). If your machine is equipped with a catalytic converter, (see “technical data”) an unleaded, oil mixed quality gasoline should always be used. A leaded gasoline will destroy the catalytic converter.Husqvarna-227R-Brush-Cutter-FIG-
\(51\)

  • This engine is certified to operate on unleaded gasoline.
  • The lowest recommended octane rating is 87. If you run the engine on lower octane rating than 87 so-called “knocking“ can occur. This leads to an increased engine temperature, which can result in a serious engine breakdown.
  • When working at continuous high revs a higher octane rating is recommended.

Two-stroke oil

  • For the best results use HUSQVARNA two-stroke oil, which has been specially developed for clearing saws and chain saws.
    Mixing ratio 1:50 (2%).

  • Never use two-stroke oil intended for water-cooled outboard motors, so-called outboard motor oil.

  • Never use oil intended of four-stroke engines.

Mixture

  • Always mix gasoline and oil in a clean container intended for fuel.
  • Always start by filling half the quantity of gasoline required. Then add the entire oil quantity. Mix (shake) the fuel mixture. Fill the remaining quantity of gasoline.
  • Mix (shake) the fuel mixture carefully before filling in the machine‘s fuel tank.
  • Do not mix more than max. one month’s supply of fuel.
  • If the machine is not used for a long period, the fuel tank should be emptied and cleaned.
  • This engine is certified to operate on unleaded gasoline.

WARNING!
The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when handling the saw near flammable substances or vapors.

Fuelling
The following precautions reduce the risk of fire:

Do not smoke or place any sources of heat in the vicinity of the fuel. Never refuel when the engine is running. Always stop the engine and let it cool for a few minutes before refueling. Open the fuel cap slowly when fuelling so that any overpressure is released slowly. Tighten the fuel cap carefully after refueling. Always move the machine from the fuelling place before starting. Husqvarna-227R-Brush-Cutter-FIG- \(53\)

  • Clean around the fuel cap. Contamination in the tank can disrupt operations.
  • Ensure that the fuel is well-mixed by shaking the container before filling the tank.

START AND STOP

Control before starting
For reasons of safety follow these recommendations!Husqvarna-227R-Brush-
Cutter-FIG- \(54\)

  • Check the blade to ensure that no cracks have formed at the bottom of the teeth or by the centre hole. The most common reason why cracks are formed is that sharp corners have been formed at the bottom of the teeth while sharpening or that the blade has been used with dull teeth. Discard a blade if cracks are found.
  • Check that the support flange is not cracked due to fatigue or due to being tightened too much. Discard the support flange if it is cracked.
  • Ensure the locking nut has not lost its captive force. The nut lock should have a locking force of at least 1.5 Nm. The tightening torque of the locking nut should be 35-50 Nm. Check that the guard is not damaged or cracked. Replace the guard if it is exposed to impact or is cracked.
  • Check that the trimmer head and spray guard are not damaged or cracked. Replace the trimmer head or spray guard if they are exposed to impact or are cracked.
  • Never use the machine without a guard or spray guard nor with a defective guard.

Start and stop

WARNING!
The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury.
Always move the machine from the filling area before starting. Place the machine on a flat surface. Ensure the cutting equipment cannot come into contact with any object. Make sure no unauthorized persons are in the working area, otherwise, there is a risk of serious personal injury. The safety distance is 15 meters.

Cold engine IGNITION : Set the stop switch to the start position. CHOKE: Set the choke control in the choke position.Husqvarna-227R-Brush-Cutter-FIG-
\(55\)
AIR PURGE: Press the air purge diaphragm repeatedly until fuel begins to fill the diaphragm. The diaphragm need not be filled.

Warm engine
Use the same starting procedure as for the cold engine, but do not set the choke control in the choke position. The start throttle position is obtained by setting the choke control in the choke position and then returning it to its original position.

Stop
The engine is stopped by switching off the ignition.Husqvarna-227R-Brush-
Cutter-FIG- \(56\)

WARNING!
When the engine is started with the choke in the choke or start position the cutting equipment starts to rotate immediately.

Start

  • Press the machine body against the ground using your left hand (NOTE! Not your foot). Grip the starter handle, slowly pull out the cord with your right hand until you feel some resistance (the starter pawls grip), now quickly and powerfully pull the cord.
  • Reset the choke control as soon as the engine fires and repeat until the engine starts. When the engine starts quickly apply full throttle and the start throttle will automatically disengage.
    NOTE! Do not pull the starter cord out completely and do not release the starter cord from the fully extended position. This can damage the machine.

MAINTENANCE

Carburetor

  • Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions.
  • After your unit has been run 8-10 tanks of fuel the engine has broken in. To ensure that your unit is at peak performance and producing the least amount of harmful emissions after break in, have your authorized servicing dealer, who has a revolution counter at his disposal, to adjust your carburetor for optimum operating conditions.
    WARNING!
    The complete clutch cover with shaft must be fitted before the machine is started, otherwise the clutch can become loose and cause personal injury.

FunctioningHusqvarna-227R-Brush-Cutter-FIG- \(57\)

  • The carburetor governs the engine speed via the throttle trigger. In the carburetor, air/fuel is mixed. This air/fuel mixture is adjustable. If you want to take advantage of the maximum output of the engine, the setting must be corret.

  • The setting of the carburetor means that the engine is adjusted to local conditions, for example climate, altitude, gasoline and type of two-stroke oil.

  • The carburetor has three adjustment possibilities:
    L= Low speed needle
    H= High speed adjustment screw
    T= Idle speed adjustment screw

  • The fuel quantity required in proportion to the airflow the throttle trigger level allows is adjusted by means of the L- and H- needles. Turning the needles clockwise gives a leaner fuel mixture (less fuel), turning them counter-clockwise gives a richer fuel mixture (more fuel). A lean mixture gives higher rpms and a rich one has lower rpms.

  • The idling speed screw T regulates the position of the throttle lever in the idling speed position. Turn the idling speed screw clockwise gives a higher idling speed, turn it counter-clockwise a lower idling speed.

Basic setting

The carburetor is set to its basic setting when the test run at the factory. The basic setting should be kept during the machine‘s first working hours. Thereafter the carburetor should be finely adjusted. Fine adjustment should be carried out by a skilled technician.
NOTE! If the cutting attachment rotates/moves in the idling position, turn the idling speed screw counter-clockwise until the blade stops.
Rec. idling speed 2 700 rpm.
Recommended max. speed: See “technical data”.

WARNING!
Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the cutting attachment stops. Do not use the machine until it has been properly adjusted or repaired.

Fine adjustment

When the machine has been ”run-in” the carburetor should be finely adjusted. The fine adjustment should be carried out by a qualified person. First adjust the L-jet, then the idling screw T and then the H-jet.

Conditions

  • Before any adjustments are made the airfilter should be clean and the airfilter cover fitted. Adjusting the carburetor while a dirty air filter is in use will result in a leaner mixture when the filter is finally cleaned. This can give rise to serious engine damage.
  • Carefully turn the L and H needle to the midpoint between fully turned in and fully turned out.
  • Do not attempt to adjust the needles beyond the stops as damage can occur.
  • Now start the machine according to the starting instructions and run it warm for 10 minutes.

NOTE! If the cutting attachment rotates/moves the T screw should be turned anti-clockwise until the cutting attachment stops.

Low-speed needle L

Try to find the highest idling speed, turning the low-speed needle L clockwise respectively counter-clockwise. When the highest speed has been found, turn the low-speed needle L 1/4 turn counter-clockwise. NOTE! If the cutting attachment rotates/moves in the idling position, turn the idling speed screw T counter-clockwise until the cutting attachment stops.

Final setting of the idling speed T

  • Adjust the idling speed with the screw T, If it is necessary to readjust. First turn the idle speed adjusting screw T clockwise until the cutting attachment starts to rotate/ move.
  • Then turn, counterclockwise until the cutting attachment stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position.
  • It should also be good margin to the rpm when the cutting attachment starts to rotate/move.
    CAUTION! Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the cutting attachment stops. Do not use the machine until it has been properly adjusted or repaired.

High-speed needle HHusqvarna-227R-Brush-Cutter-FIG-
\(60\)
The high-speed needle affects the machine’s power, speed, temperature and fuel consumption. A too lean adjustment on the high-speed needle H (the high-speed needle H is screwed in too much) gives a too high speed resulting in engine damage. Do not allow the engine to run at full speed for more than 10 seconds. Apply full throttle and turn the high-speed needle H slowly anticlockwise until the engine runs unevenly. The high-speed needle H is then turned slowly clockwise a little until the engine runs smoothly.
Note the engine should be run unloaded when H adjusts the high-speed needle. Therefore dismantle the cutting equipment, nut, support flange and disc drive before adjusting the high-speed needle. The high-speed needle is adjusted correctly when the machine ‘splatters’ a little . If the machine smokes heavily at the same time as it ‘splatters’ heavily the adjustment is too rich.
NOTE! For optimum setting of the carburetor, contact a qualified servicing dealer who has a revolution counter at his disposal.

Correctly adjusted carburetor

  • A correctly adjusted carburetor means that the machine accelerates without hesitation and the machine 4-cycles a little at max speed. Furthermore, the cutting attachment must not rotate/move at idling. A too lean adjusted low speed needle L may cause starting difficulties and bad acceleration.
  • A too lean adjusted high speed needle H gives lower power = less capacity, bad acceleration and/or damage to the engine.
  • A too rich adjustment of the two speed needles L and H gives acceleration problems or too-low working speed.

Muffler
NOTE!
Some mufflers are fitted with a catalytic converter. See “Technical data” to see whether your clearing saw is fitted with a catalytic converter. The muffler is designed to dampen the noise level and to direct the exhaust fumes away from the user. The exhaust fumes are hot and can contain sparks, which can result in fire if the exhaust fumes are directed toward a dry and inflammable material. Some mufflers are equipped with a special spark arrest screen. If your machine is fitted with this type of screen it should be cleaned regularly. This is done using a wire brush. On mufflers without a catalytic converter, the screen should be cleaned weekly, or replaced if necessary. On mufflers fitted with a catalytic converter the screen should be checked and cleaned monthly. If the screen is damaged it should be replaced. If the screen is frequently blocked, this can be a sign that the function of the catalytic converter is impaired. Contact your dealer to inspect the muffler. A blocked screen will cause the engine to overheat resulting in damage to the cylinder and piston. Also see under “Maintenance”.Husqvarna-
227R-Brush-Cutter-FIG- \(61\)

NOTE!
Never use a machine with a defective muffler.

WARNING!
Mufflers fitted with catalytic converters become extremely hot during use and after stopping. This also applies at idling speeds. Contact can result in burns to the skin. Be observant to the risk of fire!

Cooling system
To maintain as low opera-ting temperature as possible the engine is equipped with a cooling system.

The cooling system consists of:

  1. An air intake on the starter unit.
  2. Cooling fins on the flywheel.
  3. Cooling fins on the cylinder
  4. Cylinder cover (leads cold air onto the cylinder).

Clean the cooling system using a brush at least once a week, in difficult conditions more often.
A dirty or blocked cooling system leads to the engine overheating resulting in damage to the cylinder and piston.

Angle gear

The angle gear is filled with a sufficient quantity of grease at the factory. However, before using the machine you should check that the angle gear is filled to 3/4 with grease. Use HUSQVARNA special grease.
Normally, the grease does not need to be changed except when the angle gear is repaired.

Air filter
The air filter should be cleaned regularly removing dust and dirt to avoid:

  • carburetor malfunction
  • starting problems
  • reduced engine power
  • unnecessary wear to engine parts
  • abnormal fuel consumption

Clean the filter after every
25 hours or more regularly if operating conditions are exceptionally dusty.

Cleaning the air filter

Dismantle the air filter cover and remove the air filter. Wash in clean, warm soapy water. Ensure that the filter is dry before refitting. An air filter used for a long period of time can never be cleaned completely. Therefore it is necessary to replace the filter from time to time with a new filter. A damaged air filter must always be replaced.
If the machine is used in dusty conditions the air filter should be soaked in oil, see the section on “Oiling the air filter“.

Oiling the air filter

Always use HUSQVARNA filter oil, order no. 503 47 73-01. The filter oil con- tains a solvent to make it spread evenly through the filter. You should therefore avoid skin contact. Put the filter in a plastic bag and the pour the filter oil over it.
Knead the plastic bag to distribute the oil. Squeeze the excess oil out of the filter inside the plastic bag and pour off the excess before fitting the filter on the machine. Never use common engine oil. This would drain through the filter quite quickly and collect in the bottom.

Two-part shaft
The end of the drive axle in the lower shaft should be lubricated with grease every 30 hours. There is a risk that the drive axle ends (splined coupling) on two-part shafts jam if they are not lubricated regularly.

Spark plug
The condition of the spark plug is affected by:

  • An incorrect carburetor setting.
  • An incorrect fuel mixture (too much or faulty oil).
  • A dirty air filter.

These factors cause deposits on the spark plug electrode that may result in malfunction or starting\ difficulties.
If the machine is low on power, difficult to start or runs poorly while idling always check the spark plug first.
If the spark plug is dirty, clean it and at the same time check that the electrode gap is 0.5 mm. The spark plug should be changed after about one month of operation or earlier if necessary.
NOTE! Always use the recommended type of spark plug. An incorrect spark plug can damage the cylinder/piston.

Filing the grass blade

WARNING! Always stop the engine before starting work on any part of the cutting equipment. This continues to rotate even after the throttle has been released. Ensure that the cutting equipment has stopped completely and remove the cable from the spark plug before you start to work on it.

  • See the cutting equipment’s packaging for correct filing instructions.
  • The blades are sharpened using a single cut flat file.
  • Sharpen all edges equally to maintain the balance of the blade.

WARNING!
Always discard a blade that is bent, twisted, cracked, shattered or damaged in any other way. Never attempt to straighten a twisted blade for use again. Only use original blades of the prescribed type.

Sharpening the clearing blade

Husqvarna-227R-Brush-Cutter-FIG-
\(69\)

WARNING!
Incorrect cutting equipment or an incorrectly sharpened blade increases the risk of kickback.

  • See the cutting equipment’s packaging for correct filing instructions.
  • A correctly sharpened blade is a prerequisite for working efficiently and to avoid unnecessary wear to the blade and clearing saw.
  • Make sure that the blade is well supported when you use the file. Use a 5.5 mm round file with a file holder.
  • The sharpening angle is 15°. Every other tooth is sharpened to the right and the intermediate tooth to the left. When the blade has been heavily pitted by stones the upper side of the teeth can, in exceptional cases, need to be dressed using a flat file. In such cases this takes place before sharpening with the round file. Dressing the top side must be carried out equally for all teeth.
  • Adjust the setting. This should be 1 mm.

NOTE : Use only HUSQVARNA replacement parts. Use of other brands of replacement parts can cause damage to your unit or injury to the operator or others. Your warranty does not cover damage or liability caused by the use of accessories and/or attachments not specifically recommended by HUSQVARNA.

  • As the small nonroad engine owner, you should, however, be aware that Husqvarna Forest & Garden may deny you warranty coverage if your small nonroad engine or a part of it has failed due to abuse, neglect, improper maintenance, unapproved modifications or the use of parts not made or approved by the original equipment manufacturer.
