3.7 Chain saw safety warnings

• Keep all parts of the body away from the saw chain when the chain saw is operating. Before you start the chain saw, make sure the saw chain is not contacting anything. A moment of inattention while operating chain saws may cause entanglement of your clothing or body with the saw chain.
• Always hold the chain saw with your right hand on the rear handle and your left hand on the front handle. Holding the chain saw with a reversed hand configuration increases the risk of personal injury and should never be done.
• Hold the power tool by insulated gripping surfaces only, because the saw chain may contact hidden wiring. Saw chains contacting a “live” wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.
• Wear safety glasses and hearing protection. Further protective equipment for the head, hands, legs, and feet is recommended. Adequate protective clothing will reduce personal injury by flying debris or accidental contact with the saw chain.
• Do not operate a chainsaw in a tree. Operation of a chainsaw while up in a tree may result in personal injury.
• Always keep proper footing and operate the chain saw only when standing on a fixed, secure, and level surface. Slippery or unstable surfaces such as ladders may cause a loss of balance or control of the chain saw.
• When cutting a limb that is under tension be alert for spring back. When the tension in the wood fibers is released the spring-loaded limb may strike the operator and/or throw the chainsaw out of control.
• Use extreme caution when cutting brush and saplings. The slender material may catch the saw chain and be whipped toward you or pull you off balance.
• Carry the chain saw by the front handle with the chain saw switched off and away from your body. When transporting or storing the chain saw always fit the guide bar cover. Proper handling of the chain saw will reduce the likelihood of accidental contact with the moving saw chain.
• Follow instructions for lubricating, chain tensioning, and changing accessories. The improperly tensioned or lubricated chain may either break or increase the chance for kickback.
• Keep handles dry, clean, and free from oil and grease. Greasy, oily handles are slippery causing loss of control.
• Cut wood only. Do not use a chain saw for purposes not intended. For example: do not use a chain saw for cutting plastic, masonry or non-wood building materials Use of the chain saw for operations different than intended could result in a hazardous situation.

3.8 Causes and operator prevention of kickback
Kickback may occur when the nose or tip of the guide bar touches an object, or when the wood closes in and pinches the saw chain in the cut.
Tip contact in some cases may cause a sudden reverse reaction, kicking the guide bar up and back toward the operator. Pinching the saw chain along the top of the guide bar may push the guide bar rapidly back toward the operator. Either of these reactions may cause you to lose control of the saw which could result in serious personal injury.
Do not rely exclusively upon the safety devices built into your saw. As a chain saw user, you should take several steps to keep your cutting jobs free from accidents or injuries. Kickback is the result of tool misuse and/or incorrect operating procedures or conditions and can be avoided by taking proper precautions as given below:

• Maintain a firm grip, with thumbs and fingers encircling the chain saw handles, with both hands on the saw, and position your body and arm to allow you to resist kickback forces. Kickback forces can be controlled by the operator, if proper precautions are taken. Do not let go of the chainsaw.

• Do not overreach and do not cut above shoulder height. This helps prevent unintended tip contact and enables better control of the chain saw in unexpected situations.

• Only use replacement bars and chains specified by the manufacturer. Incorrect replacement bars and chains may cause chain breakage and/or kickback.

• Follow the manufacturer’s sharpening and maintenance instructions for the saw chain. Decreasing the depth gauge height can lead to increased kickback. 3.9 Safety instructions for the pole-mounted pruner 3.9.1 Work Instructions (01)

• During pruning, lift the pole-mounted pruner (01/1) to a maximum angle of 60° (01/2). At a steeper angle, you inevitably get into the area where cut-off branches can fall. Always stand outside this area.

• Plan an escape route in advance for getting out of the way of falling branches. This escape route must be free of obstacles such as sawn-off branches or slippery places that could hinder getting out of the way.

• Keep a safe distance from bystanders, animals, objects or buildings, which is at least approx. 2.5x the length of the branch to be sawn off. If that is not possible, saw the branch off piece by piece.

• Do not attempt to saw a branch that has a diameter greater than the length of the chain bar.

• Avoid moving branches or objects becoming caught in the saw chain. In this case, immediately switch off the pole-mounted pruner.

• Remove the rechargeable battery from the basic appliance and push the protective cover over the saw chain for:
  ■ Testing, adjustment work and cleaning work
  ■ Work on the guide rail and saw chain
  ■ Leaving the appliance
  ■ Transport
  ■ Storage
  ■ Maintenance and repair work
  ■ Danger

• Maintain a minimum distance of 10 m to overhead electrical lines.

Vibration load
WARNING! Danger due to vibration The actual magnitude of the vibration emissions during the use of the appliance may deviate from that stated by the manufacturer. Observe the following influencing factors before or during use:

• Is the appliance being used as intended?
• Is the material being cut or processed in the proper manner?
• Is the appliance in proper condition of use?
• Is the cutting tool properly sharpened or is the correct cutting tool installed?
• Are the handle grips and any optional vibration grips mounted, and are they firmly attached to the appliance?.
• Only operate the tool at the motor speed required for the respective work. Avoid using the maximum speed in order to reduce noise and vibrations.
• The noise and vibrations of the tool may increase due to improper use and maintenance. This leads to health damage. In this case, immediately switch off the tool and have it repaired by an authorized service workshop.
• The degree of stress due to vibration depends on the work to be performed or on the use of the tool. Estimate the stress and plan appropriate work breaks. This considerably reduces stress due to vibration over the entire working time.
• Extensive use of the tool exposes the operator to vibrations, which can lead to circulatory issues (“white fingers”). To avoid this risk, wear gloves and keep your hands warm. If any symptoms of “white fingers” occur, immediately consult a physician. These symptoms include Numbness, loss of feeling, tingling, itching, pain, reduced muscular strength, and changes in the color or condition of the skin. Normally these conditions affect the fingers, hands or pulse. The risk increases at low temperatures.
• Take long breaks during your working day so you can recover from the noise and the vibrations. Plan your work in such a way that the use of appliances that generate strong vibrations is spread over several days.
• If you notice an unpleasant sensation or discoloration of the skin on your hands when using the tool, stop working immediately. Take sufficient work breaks. Without sufficient breaks, a hand/arm vibration syndrome can occur.
• Minimize your risk of being exposed to vibrations. Maintain the tool according to the instructions in the operating instructions.
• If the tool is used frequently, contact your dealer to purchase anti-vibration accessories(e.g. handles).
• Avoid working with the tool at temperatures below 10 °C. Define how the vibration load can be limited in a work plan.

3.9.3 Noise pollution
A certain level of noise exposure from this appliance is inevitable. Carry out noisy work at approved and specified time periods. Observe rest periods as necessary and restrict the duration of the work to a minimum. For your personal protection and the protection of persons in the vicinity, appropriate hearing protection must be worn.

INSTALLATION AND START-UP

4.1 Installing the guide rail and saw chain (02 – 06)
CAUTION!
Risk of injury on the saw chain The cutting edges of the saw chain are very sharp so cutting injuries can occur when handling the saw chain. Before all work with the saw chain, heed the following:

• Switch off the appliance and remove the rechargeable battery.
• Wear protective footwear.

1. Loosen (02/a) the fastening nut (02/1) of the chain sprocket cover (02/2). Remove the fastening nut and chain sprocket cover.

2. Use the screwdriver on the combination spanner to loosen the chain tensioning screw (03/1). Turn the chain tensioning screw until the chain tensioning pin (03/2) is at the rear thread end (03/a).

3. Insert the saw chain:
   • Align (04/a) the cutting teeth (04/1) of the saw chain (04/2) that are to lie at the top of the guide rail to the tip of the guide rail (04/3).
   Note: Make sure that the chain is correctly mounted!
   • Place the saw chain (04/2) in the groove (04/4) of the guide rail and guide completely around the guide rail.

4. Lay the guide rail together with the saw chain laid on it in the open housing:
   ■ Lay the saw chain (05/1) around the drive sprocket (05/2).
   ■ Align the guide rail (05/3) in such a way that the guide pin (05/4) grips in the slotted hole (05/5) of the guide rail.
   ■ Align the guide rail (05/3) so that the chain tensioning pin (05/6) grips in one of the two chain tensioning holes (05/7).
   ■ Align the saw chain (05/1) so that it is in contact in the groove of the guide rail (05/3) and on the drive sprocket (05/2).

5. Put on the chain sprocket cover (06/1) and tighten (06/a) with the fastening nut (06/2).

6. Tension the saw chain (Tensioning and slackening the saw chain (07)).

4.2 Tensioning and slackening the saw chain (07)

1. Slightly loosen the fastening nut of the cover.

2. Tension the saw chain; use the combination spanner:
   ■ Tensioning the saw chain: Turn the chain tensioning screw (07/1) clockwise (07/a).
   ■ Slackening the saw chain: Turn the chain tensioning screw (07/1) anti- clockwise (07/b).

3. Check the chain tension (see chapter 5.2 “Checking the chain tension”, page 27). Repeat the previous step if necessary.

4.3 Filling saw chain oil (08)
There is no appliance saw chain oil in the appliance upon delivery.
IMPORTANT!
The danger of damage to the appliance Use of the appliance without saw chain oil leads to damage of the saw chain and the guide rail.
■ Never operate the appliance without saw chain oil.
■ Before starting work, fill the saw chain oil in the oil tank and check the oil level during the work.
■ At least before starting work each time, check that the chain lubrication is working.
The service life and cutting performance of the saw chain depend on optimum lubrication. The saw chain has oil applied to it automatically during operation.

IMPORTANT!
The danger of damage to the appliance Due to the metallic abrasion it contains, the use of used oil for lubricating the chain would lead to premature wear of the guide rail and saw chain. Also, the warranty of the manufacturer will become void.

• Never use used oil, only biologically degradable saw chain oil.

IMPORTANT!
The danger of environmental damage
The use of mineral oil for chain lubrication leads to serious environmental damage.

• Never use mineral oil, but only biologically degradable saw chain oil.

Each time before starting work or changing the rechargeable battery, check the oil level, and replenish the saw chain oil if necessary:

1. Check the oil level in the viewing aperture (08/1) of the oil tank. It must always be possible to see oil.
   The minimum and maximum oil levels must not be exceeded.

2. Place and hold the pole-mounted pruner horizontally on a firm surface.

3. Clean the appliance around the oil tank cap (08/2).

4. Unscrew the oil tank cap (08/2).

5. Fill the oil tank with biologically degradable saw chain oil. While doing so, check the oil level in the viewing aperture (08/1) of the oil tank. Do not allow it to overrun.
   ■ Use a funnel for easier filling.
   ■ Do not allow any dirt to get into the oil tank.

6. Screw down the oil tank cap (08/2) again.

OPERATION

CAUTION!
Danger of burns
The gearbox housing becomes hot during operation.
Do not touch the gearbox housing.

5.1 Switching the appliance on and off
See “Multitool MT 42 – basic appliance” operating instructions.

5.2 Checking the chain tension Frequently check the chain tension, because new saw chains stretch. 1. Pull through the saw chain a little by hand and, while doing so, check:

• When cold: The saw chain has been tensioned correctly when it can be lifted by approx. 3 – 4 mm in the middle of the guide rail and can be pulled through easily by hand. At operating temperature, the saw chain stretches and hangs down.
• The drive links of the saw chain are not allowed to come out of the groove on the underside of the guide rail – otherwise, the saw chain could jump off. 2. Re-tension the saw chain if necessary (Tensioning and slackening the saw chain (07)).

5.3 Checking the chain lubrication
Check the function of the automatic chain lubrication by switching on the pole-mounted pruner and pointing its tip toward a piece of cardboard or paper placed on the ground.
IMPORTANT! The danger of damage to the appliance Ground contact invariably leads to blunting of the saw chain.

• Do not make contact with the ground with the chain and maintain a safe distance of 20 cm. 1. Switch on the appliance. 2. Hold the tip of the guide rail in the direction of a cardboard box or paper on the ground.
• If the check produces a growing trace of oil, this indicates the automatic oiling function is operating correctly.
• If there is no trace of oil even though the oil tank is full: Clean the oil entry hole in the appliance and the groove of the guide rail. If this is not successful, please contact our customer service.

WORKING BEHAVIOUR AND WORKING TECHNIQUE (09 – 13)

WARNING! Increased risk of falling There is a greater risk of falling if work is carried out from an elevated position (e.g. ladder).

• always work with the appliance from the ground and make sure that you are standing securely.
• Heed the safety instructions.
• Where possible, stand so that the cut can be carried out at an angle of 90° to the branch (09/a).
• Saw off thick branches in sections in order to have better control over the point of impact (10/1).
• Never saw in the flaring at the beginning of the branch in order to improve the healing of the wound and to avoid rot (11).
• Press (12/a) the pole-mounted pruner against the branch (12/2) with the tree grip (12/1) when sawing to stabilize it on the branch.
• Before the branch is sawn off (13/b), make a relief cut (13/a) on the underside of the branch. This can avoid the bark from tearing off and causing difficult-to-heal damage to the tree. The relief cut should not be deeper than 1/3 of the branch thickness to avoid any trapping of the pole-mounted pruner.
• Always pull the pole-mounted pruner with a rotating saw chain out of the branch so that it does not become trapped.

MAINTENANCE AND CARE

WARNING!
The danger of cutting injuries
The danger of cutting injuries when reaching into sharp-edged, moving appliance parts and into cutting tools.

• Before maintenance, care, and cleaning work, always switch off the appliance. Remove the rechargeable battery.
• Always wear protective gloves during maintenance, care, and cleaning work.

7.1 Saw chain and guide rail
Replacing the saw chain and guide rail Replacing the saw chain and guide rail The saw chain and guide rail are exposed to significant wear. Change the saw chain and guide rail immediately if the correct function is not assured. 7.1.2 Turning the guide rail In order to avoid one-sided wear on the guide rail, turn it every time the chain is changed.
Sharpening the saw chain
CAUTION! Risk of injury due to kickback Damaged or incorrectly sharpened saw chains increase the danger of kickback! This can result in injuries.

• Clean the saw chain regularly.
• Check the saw chain regularly for damage and replace if necessary.
• If you are not familiar with sharpening the chain: Contact our relevant customer service.

The saw chain must be sharpened in the following cases:

• Only sawdust is thrown out, rather than wood chips.
• The pole-mounted pruner must have to be forced through the wood during pruning.
  For the inexperienced user: Have the saw chain sharpened by a specialist/customer service. If you are sharpening the saw chain yourself, heed the following values.  Accessories can be obtained from specialist retailers.
  

NOTE Only remove a little material when sharpening! We recommend using a chain sharpening tool for sharpening your saw chain.
Cleaning the guide rail

1. Clean the guide rail, the groove of the guide rail, and the oil outlet openings regularly.
2. Use a flat file to remove the burrs that have built up on the guide rail due to the saw chain.

7.2 Checking and cleaning the drive sprocket The load on the drive sprocket (05/2) is particularly intense. Therefore, perform the following tasks:

1. Check the teeth of the drive sprocket regularly for wear or damage.
2. Clean the drive sprocket and guide rail attachment with a brush.

NOTE
A worn or damaged drive sprocket reduces the service life of the saw chain, so the drive sprocket should be renewed without delay by customer service.

STORAGE

Thoroughly clean the appliance after each use and – if present – attach all covers. Store the appliance in a dry, lockable place out of the reach of children. Carry out the following jobs before intervals in work lasting for longer than 30 days:

1. Empty the oil tank for the saw chain oil.
