5. To quickly detach the grass trimmer from the harness, pull the quick-release latch tab upward.
6. Insert the latch tongue in the slot of the quick release latch to reattach the grass trimmer to the harness.
  • STARTING PROCEDURE

    • Dayliff trimmers use two-stroke fuel, a blend of petrol and 2-stroke engine oil in proportions tabulated below.DAYLIFF-B25-Shamba-Tool-Trimmers- \(10\)

    • Check and confirm that the fuel tank has sufficient fuel for the work or add fresh fill of 2 stroke fuel as above.

    • It is recommended that the 2 stroke is mixed in a separate container before filling into the fuel tank.
      WARNING

    • Store fuel only in a clean, safe, approved container. Check and follow local rules on type and location of storage container.

    • Two-stroke fuel may separate hence shake fuel container thoroughly before each use.

    • Stored fuel also ages. Do not mix more fuel than you expect to use within a period, say a month.
      When preparing fuel mixture, mix only the amount needed for the job you are to do.

    • Do not use fuel that has been stored longer than two months. Fuel mixture stored longer than this will cause hard starting and poor performance. If fuel mix has been stored longer than this time, it should be removed and filled with fresh mixture.

  • Starting Cold Engine

1. Move the stop switch to ‘START’ position.
2. Give a gentle push on the primer pump repeatedly (7-10 times) until fuel comes into the primer pump.
3. Cold starts: Pull lever up to choke position.
4. Pull starter handle until engine false fires.
5. Push choke lever inwards (excessive cranking with choke lever will cause flooding engine making it difficult to start).
6. Pull starter handle until engine starts.
7. Allow engine to warm up for a few minutes before using.![DAYLIFF-B25-Shamba-Tool-Trimmers- \(11\)](https://manuals.plus/wp-content/uploads/2024/04/DAYLIFF-B25-Shamba-Tool-Trimmers-11.png)
  • Starting Warm Engine
    If the engine has been in operation for a period and is still warm, it can be restarted without pulling the choke lever out.

  • Stopping the Engine
    Move switch to stop position

  • Using the TrimmerDAYLIFF-B25-Shamba-Tool-Trimmers- \(12\)

    • Line head rotates in a counter CLOCKWISE direction. The CUT-OFF KNIFE will be on the right side of the debris shield.
      WARNING The proper debris shield must be in place on the unit when the nylon cutting line is used. The cutting line can flap around if too much line is exposed. Always use the plastic debris shield with cut-off knife when using nylon cutting heads.

    • For nearly all cutting, it is good to tilt the line head so that contact is made on the part of the line circle where the line is moving AWAY from operator and the debris shield. This results in the debris being thrown away.

    • WARNING

    • Tilting the head to the wrong side will shoot the debris forward, towards the operator. If the line head is held flat to the ground so that cutting occurs on the whole line circle, debris will be thrown at the operator.

    • Use only quality nylon monofilament of 2.5mm diameter. Never use wire or wire-reinforced line in place of nylon trimmer line. Load the nylon line cutting head only with nylon trimmer line of the proper diameter.

    • Exercise caution when operating over bare spots and gravel, because the line can throw small rock particles at high speeds. Debris shields on the unit cannot stop objects which bounce or ricochet off hard surfaces.DAYLIFF-B25-Shamba-Tool-Trimmers- \(13\)

  • TRIMMING:

    • This is feeding the trimmer carefully into the material to be cut. Tilt the head slowly to direct debris away from you. If cutting up to a barrier such as fence, wall or tree, approach from an angle where any debris ricocheting off the barrier will fly away from operator. Move the line head slowly until the grass is cut right up the barrier, but do not jam(overfeed )the line into the barrier.
    • If trimming up to a wire mesh or chain linked fence be careful to feed only up to wire, else the line may snap off around the wire. Trimming can be done to cut through weed stems one at a time. Place the trimmer line head near the bottom of the weed-never high up which could cause the weed to chatter and catch the line. Rather than cut the weed right through, use the very end of the line to wear through the stem slowly.
  • SCALPING AND EDGING:

    • Both of these are done with the line head tilted at a steep angle Scalping is removing top growth leaving the earth bear.
    • Edging is trimming the grass back where it has spread over a sidewalk or drive way. During both edging and scalping, hold the unit at a steep angle and in a position where the debris, and any dislodging dirt and stones, will not come back towards the operator even if it ricochets off the hard surface.
    • WARNING  Do not trim in an area where there are strands of fencing wire.
  • INSTALLING NYLON CUTTER HEAD

    • Insert the hex key (2) into the specific hole in the angle transmission (3) and rotate the cutting line head (1) by hand until the hex key enters the inner hole, blocking rotation.
    • Ensure that the grooves in the inner ring-nut (4) match up perfectly with the angle transmission (3).
    • Fit the cutting line head (1 screwing it up in an anticlockwise direction.
    • Remove the hex key (2)DAYLIFF-B25-Shamba-Tool-Trimmers- \(14\)

HEDGING HEAD

  • Direction of use
    Before starting work check the following:

    • All the screws on the machine and the blade are tightly fastened
    • Blades are sharp and there are no signs of any damage
    • Protection devices are well fastened and working efficiently
    • Handgrips are well fastened
    • Cut branches up to a maximum diameter of 4.5mm; cutting branches with a larger diameter may damage the trimmer.
    • ONLY adjust the tilt angle with the motor switched off. SWITCH OFF the motor before removing any branches caught up in the blades.
    • Never bring the blades close to body parts while working.
    • Always fit the blade guards when the device is switched off
  • Adjustment of blade inclination

    • Turn the engine off and wait for the blade to stop.
    • Loosen the knob (1) and incline the cutting device (2) as desired, see picture 3.
    • Tighten the knob (1) securely. If the knob does not move enough to guarantee it is tight, extract it and re-position it so that it can be tightened securely.DAYLIFF-B25-Shamba-Tool-Trimmers- \(16\)
  • VERTICAL TRIMMING

    • Proceed to cut by using curved movements from the bottom towards the top, keeping the blade as far from the body as possible.DAYLIFF-B25-Shamba-Tool-Trimmers- \(17\)
  • HORIZONTAL TRIMMING

    • The best results will be obtained with the blade slightly inclined (5° – 10°) in the direction of the cut, proceed with a curved movement, slowly and without interruptions, especially in the case of very thick hedges.DAYLIFF-B25-Shamba-Tool-Trimmers- \(18\)
  • LUBRICATING THE BLADES DURING JOBS

    • If the cutting device gets excessively hot during operations, grease the blade’s internal surfaces with the correct oil.DAYLIFF-B25-Shamba-Tool-Trimmers- \(19\)
      This operation must only be performed when the blades have stopped running and the motor is switched off.
  • BLADE REDUCTION GEAR GUARD

    • Lubricate every 20 hours through the grease nipples provided.
    • Only use lithium-based grease for high temperatures and extreme pressures.DAYLIFF-B25-Shamba-Tool-Trimmers- \(20\)
  • MAINTENANCE AND SHARPENING OF THE BLADE
    Periodically check to ensure the blades are not bent or damaged and that the fixed comb on the blade is intact.

    • Adjustment of the distance between blades is not necessary, as this is predetermined by the manufacturer.
    • If the blades are used correctly, following all the instructions provided, they will not require any maintenance work and will not need sharpening.
    • It is necessary to sharpen the blades only when the trimming performance decreases and the branches tend to stick together.
      WARNING Any intervention on the blade should always be conducted at a specialised Centre that has the most appropriate tools and is able to perform the operations without compromising the safety of the machine.
  • PRUNING HEAD

    • CHECK POINTS BEFORE OPERATION
    • Check for loose bolts, nuts and fittings.
    • Check to be sure that protector is securely in place.
    • Check to be sure that blade is not cracked.

USING THE UNIT

Preparations

  • Wear suitable protective clothing, observe safety precautions.
  • Adjust telescoping shaft to the required length.
  • Start the engine.
  • Put on the shoulder strap.

Cutting Sequence
To allow branches to free fall cut the lower branches first. Prune heavy branches (large diameter) in several controllable pieces.

Never stand directly underneath the branch you are cutting, be wary of falling branches. Note that a branch may spring back after it hits the ground with risk of injury. Remove branches in sections.

Working Techniques
Hold the control handle with the right hand, and the shaft with the left hand. The left arm should be extended to the most comfortable position. Always hold the shaft with the left hand in the area of the handle hose. The shaft should always be held at an angle of 60° or less. The least tiring working position is a tool angle of 60°.Any lesser angle may be used to suit the situation concerned.

WARNING When using the machine, if the saw chain is locked by the branch, move over the saw and then saw the branch over again.

Cross Cut
To avoid pinching the bar in the cut, position the cutting attachment with the hook against the branch and then perform the cross-cut from the top downwards.

Relieving Cut
To avoid tearing the bark on thick branches, always start by performing a relieving cut (1) on the underside of the branch. To do this, apply the cutting attachment and pull it across the bottom of the branch in an arc as far as the bar nose. Perform the cross-cut (2) – position the bar with the hook against the branch and then perform the crosscut.DAYLIFF-B25-Shamba-
Tool-Trimmers- \(21\)

Flushing Cutting Thick Branches
If branch diameter is more than 4 in (10 cm), first perform undercut (3) and then cross-cut at a distance of about 8 in./20 cm (A) from the final cut. Then carry out the flush-cut (4),starting with relieving cut and finishing with a cross-cut.

Cutting Above Obstacles:
The unit’s long reach makes it possible to prune branches that are overhanging obstacles, such as rivers or lakes. The tool angle in this case depends on the position of the branch.

Cutting From a Lift Bucket:
The unit’s long reach enables cutting to be performed next to the trunk without the risk of the lift bucket damaging other branches. The tool angle in this case depends on the position of the branch.

Mounting the Bar and Chain

  • Removing the Chain Sprocket Cover
    • Unscrew the cover and remove the cover(1).
    • Turn the screw (2)counterclockwise until the tensioner slide butts against the left end of the housing slot, then back it off 5 full turns.
      WARNING Guide-bar and chain adjustments can only be made with the engine stopped.

Fitting The Chain
WARNING Wear work gloves to protect your hands from the sharp cutters.

  • Fit the chain – start at the bar nose.

  • Fit the guide bar over the screw hole(3) and engage peg of tensioner slide in the hole (4) –place the chain over the sprocket (5) at the same time.

  • Turn the tensioning screw (1) clockwise until there is very little chain sag on the underside of the bar and the drive link tangs are engaged in the bar groove.

  • Refit the cover and screw on the nut finger tight.
    Retensioning during cutting work:

  • Stopping the engine.

  • Loosen the nut.

  • Hold the bar nose up.

  • Use a screwdriver to turn the tensioning screw (1) clockwise until the chain fits snugly against the underside of the bar.

  • While still holding the bar nose up, tighten down the nut firmly.

  • A new chain has to be retensioned more often than one that has been in use for some time.

  • Check chain tension frequently.

Checking Chain Tension

  • Shut off the engine.
  • Wear work gloves to protect hands.
  • The chain must fit snugly against the underside of the bar and it must still be possible to pull the chain along the bar by hand.

Adjusting the Throttle Cable

  • A properly adjusted throttle cable is the precondition for correct operation in the full throttle, starting throttle and idle positions.
  • Adjust the throttle cable only when the unit is completely and properly assembled.
  • Press down the throttle trigger lockout (1) and squeeze the throttle trigger (2) (full throttle) – this sets the throttle cable correctly.

Chain Lubricant
Only use recommended lubricant. A full chain oil tank is sufficient for only half a tankful of fuel. Check the oil level regularly during cutting work. Never allow the oil tank to run dry.

Preparations

  • Thoroughly clean the oil filler cap and the area around it to ensure that no dirt falls into the tank.
  • Position the machine so that the filler cap is facing up.

Opening the Filler Cap

  • The bayonet-type oil tank filler cap with hinged grip can be opened and closed without tools.
  • To open the tank, swing the grip to the vertical position.
  • Turn the filler cap counterclockwise as far as stop and remove.

Filling up with Chain Oil

  • Filling up with chain oil.
  • Take care not to spill chain oil while refilling and do not overfill the tank.

Closing the Filler Cap

  • To close the oil tank, place the filler cap in position with the grip upright, making sure the recesses are in alignment.
  • Turn the filler cap clockwise as far as stop.
  • Fold the grip down so that it is flush with the top of the cap.
    If the oil level in the tank does not go down, the reason may be a fault in the oil supply system: Check chain lubrication, clean the oilways.

Checking Chain Lubrication

  • The saw chain must always throw off a small amount of oil
  • Never operate your saw without chain lubrication. If the chain runs dry, the whole cutting attachment will be irretrievably damaged within a very short time. Always check chain lubrication and the oil level in the tank before starting work. Every new chain has to be broken in for about 2 to 3 minutes.After breaking in the chain, check chain tension and adjust if necessary – see “Checking Chain Tension”.

PREPARING FOR OPERATIONS

Adjusting the Telescoping Shaft
WARNING Always shut off the engine to fit the chain guard.

  • Loosen the screw.
  • Adjust shaft to the required length.
  • Tighten down the screw firmly.

Fitting the Harness
The type and style of the harness depend on the market.

  • Put on the shoulder strap.
  • Adjust the length of the strap.
  • With the power tool attached, the carabiner must be at about the same height as the right hip.
    WARNING To quickly detach the pole saw from the shoulder strap ,pull the quick-release latch tab upward.DAYLIFF-B25-Shamba-Tool-Trimmers-

Controls

  1. Throttle trigger lockout
  2. Throttle lever
  3. Slide switch

Starting
Press down the trigger lockout lever and squeeze the throttle lever and hold them in that position. Move the slide switch to START and hold it there. Now release the throttle lever, slide switch and trigger lockout in order. This is the starting throttle position. Set the choke knob: if the engine is cold for warm start – also use this position if the engine has been running but is still cold. Press the fuel pump bulb at least five times – even if the bulb is already filled with fuel.

  • Starting Method 1:

    • Remove the blade scabbard. Check that the chain is not touching the ground or any other obstacles.
    • Place the unit on the ground: It must rest securely on the engine support and the hook. If necessary, rest the hook on a raised support (e.g. a branch, mound or something.
    • Make sure there is safe and secure footing.
    • Hold the unit with the left hand on the fan housing and press down firmly – the operators thumb should be under the fan housing.
      WARNING Check that nobody is standing within the working range of the pruner.
      WARNING  Do not stand or kneel on the drive tube. This will bend the drive tube and may result in permanent damage.
  • Starting Method 2:

    • Remove the chain guard. Position the shaft on a branch so that it is held by the hook.
    • Hold the unit firmly with the left hand on the fan housing – the thumb should be under the fan housing.
    • Hold the starter grip with the right hand.
    • Pull the starter grip slowly until it engages and then give it a brisk strong pull.
    • Do not let the starter grip snap back. Guide it slowly back into the housing so that the starter rope can rewind properly.
    • Crank the engine until it begins to fire. After no more than five attempts, turn the choke knob to continue cranking.
      WARNING Do not pull out the starter rope all the way – it might otherwise break.
      WARNING Make sure the carburetor is correctly adjusted. The saw chain must not rotate when the engine is idling.

As soon as the engine runs:

  • Slip the throttle trigger to disengage the starting throttle position. The slide switch moves to the normal run position and the engine settles down to idle speed.
  • Open the throttle slightly.
  • Warm up the engine for a short period.

If the Engine does not start:
If the choke knob is not turned quickly enough after the engine begins to fire, the combustion chamber may become flooded.

  • Turn the choke knob to set the slide switch, lockout lever and throttle lever to the starting throttle position.
  • Start the engine by pulling the starter rope briskly – 10 to 20 pulls may be necessary.

Fuel Tank run until completely dry:

  • After refueling, press the fuel pump bulb at least five times – even if the bulb is filled with fuel.
  • Set the choke knob according to engine temperature.
  • Start the engine.

Shut off the Engine:
WARNING: Push the slide switch to the stop position to shut down the engine

Operating Instructions

During Break-in Period
A factory-new machine should not be run at high revs (full throttle off load) for the first three tank fillings.

This avoids unnecessary high loads during the break-in period. As all moving parts have to bed in during the break-in period, the frictional resistance in the engine are greater during this period. The engine develops its maximum power after about 5 to 15 tank fillings.

WARNING: Do not make the mixture leaner to achieve an apparent increase in power – this could damage the engine.

  • Check chain tension frequently: A new chain has to be retensioned more often than one that has been in use for some time.
  • Chain cold: Tension is correct when the chain fits snugly against the underside of the bar and can still be pulled along the bar by hand. Retension if necessary –see”Tensioning the Saw Chain”.
  • Chain at operating temperature: The chain stretches and begins to sag. The drive links must not come out of the bar groove – the chain may otherwise jump off the bar.
  • After long period of full-throttle operation: Allow engine to run for a short while at idle speed so that engine heat can be dissipated by the flow of cooling air. This protects engine-mounted components (ignition, carburetor) from thermal overload

WARNING The chain contracts as it cools down. If it is not slackened off, it can damage the gear shaft and bearings.

After Finishing Work

  • Slacken off the chain if retensioned at operating temperature during cutting work.
  • Storing for a short period Wait for the engine to cool down. Drain the fuel tank. Store the machine in a dry location. Check the tightness of all accessible screws and nuts (not adjusting screws) at regular intervals and retighten if necessary.

Taking Care of the Guide

  • Turn the bar over – every time the chain is sharpened and every time it is replaced – this helps avoid one-sided wear, especially at the nose and underside of the bar.
  • Regularly clean the oil inlet hole, the oilway and the bar. If groove depth is less than specified: Replace the guide bar.The drive link tangs will otherwise scrape along the bottom of the groove –the cutters and tie straps will not ride on the bar rails groove.
  • Measure the groove depth – with the scale on the filing gauge (special accessory) – in the area used most for cutting.

WARNING: Before every cut, mark sure that the cutting attachment stops turning when the engine idles.

Checking and Replacing the Chain Sprocket

  • Remove the chain sprocket cover, chain and guide bar.

Replace the Chain Sprocket

  • After using two saw chains or sooner.
  • If the wear marks (a) are deeper than 0.02 in (0.5 mm) since this would reduce the life of the chain. Use a gauge (special accessory) to check the depth of the wear marks. It is best to use two saw chains in rotation with one sprocket.

Maintaining and Sharpening the Saw Chain

  • Cutting effortlessly with a correctly sharpened chain
    A properly sharpened chain slices through wood effortlessly and requires very little feed pressure.Do not work with a dull or damaged chain as it will increase the physical effort required, produce unsatisfactory results and a higher rate of wear.

    • Clean the chain.
    • Check the chain for cracks in the links and damaged rivets.
    • Replace any damaged or worn parts of the chain and match the new parts to the shape and size of the original parts. Carbide-tipped saw chains are particularly wear resistant. The saw chain cannot be locked in place on the guide bar. Therefore, it is best to remove the chain from the bar and resharpen it on a workshop sharpening tool (FG 2, HOS, USG)DAYLIFF-B25-Shamba-Tool-Trimmers- \(33\)
      WARNING It is absolutely essential to comply with the angles and dimensions specified below. If the saw chain is incorrectly sharpened – and in particular if the depth gauge is set too low – there is an increased risk of kickback, with resulting risk of injury.

Use only special saw chain sharpening files. Other files have the wrong shape and cut. Select file diameter according to chain pitch. Ensure to observe certain angles when resharpening the chain cutter.

The specified angles A and B are obtained automatically if the recommended files or sharpening tools and correct settings are used. The angles must be the same on all cutters. If the angles are uneven: Chain will run roughly, not in a straight line, wear quickly and finally break. As these requirements can be met only after sufficient and constant practice:

  • Use a file holder: A file holder must be used for manual resharpening. The correct filing angles are marked on the file holder.

ENGINE MANAGEMENT

Cleaning the Air Filter

  • Accumulated dust in the air filter will reduce engine efficiency, increase fuel consumption and allow abrasive particles to pass into the engine. Remove the air filter as often as necessary to maintain a clean condition.
  • Light surface dust can readily be removed by tapping the filter. Heavy deposits should be washed out in suitable solvent.
  • Remove filter cover by loosening air filter cover knob.

Spark Plug
If engine is down on power, difficult to start or runs poorly at idling speed, first check the spark plug. Fit a new spark plug after approximately every 100 operating hours or earlier if the electrodes are badly eroded. Wrong fuel mix (too much engine oil in the gasoline), a dirty air filter and unfavorable running conditions (mostly at part throttle etc.) affect the condition of the spark plug. These factors cause deposits to form on the insulator nose which may result in trouble in operation.

Removing the Spark Plug

  • Move the slide switch to STOP.
  • Pull off the spark plug boot.
  • Unscrew the spark plug.

Checking the Spark Plug

  • Clean dirty spark plug.

  • Check electrode gap (A) and readjust if necessary see”Specifications”.

  • Use only resistor type spark plugs of the approved range. Rectify problems which have caused fouling of spark plug:– Too much oil in fuel mix.– Dirty air filter.–Unfavorable running conditions, e.g. operating at part load.
    WARNING To reduce the risk of fire and burn injury, use genuine spark plugs.

  • Always press spark plug boot (1) snugly onto spark plug terminal (2) of the proper size. (No t e: If terminal has detachable SAE adapter nut, it must be attached.) A loose connection between spark plug boot and ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire.

Installing the Spark Plug

  • Screw the spark plug (2) into the cylinder and fit the boot (1) (press it down firmly)

Storage
For periods of 3 months or longer

  • Drain and clean the fuel tank in a well ventilated area.
  • Dispose of fuel properly in accordance with local environmental requirements.
  • Run the engine until the carburetor is dry – this helps prevent the carburetor diaphragms sticking together.
  • Remove the saw chain and guide bar, clean them and spray with corrosion inhibiting oil.
  • Thoroughly clean the machine –pay special attention to the cylinder fins and air filter.
  • If using a biological chain and bar lubricant, completely fill the chain oil tank.
  • Store the machine in a dry, high or locked location, out of the reach of children and other unauthorized persons.

EXHAUST PORT AND SILENCER

  • Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and silencer may become blocked with carbon deposits. If there is power loss with the trimmer a qualified service technician will need to remove these deposits to restore performance.

ADJUSTING CARBURETOR

  • NOTE
    • Do not adjust carburetor unless necessary. If there is trouble with the carburetor, contact D&S appointed retailer or outlet. Improper adjustment may cause engine damage and void warranty.

FUEL FILTER

  • Fuel tank is fitted with a filter. Filter is situated at the free end of fuel pipe and can be picked out through fuel port with a piece of hooked wire or the like.
  • Check the fuel filter periodically. Do not allow dust to enter into fuel tank. Clogged filter will cause difficulty in starting engine or abnormalities in engine performance.
  • When filter is dirty, replace the filter.
  • When the inside of the fuel tank is dirty, it can be cleaned by rinsing the tank out with gasoline.

CHECK SPARK PLUG

  • Do not attempt to remove the plug from a hot engine in order to avoid possible damage to the threads.
  • Clean or replace the plug if fouled with heavy oily deposits.
  • Replace the plug if the center electrode is worn rounded at the end.
  • Spark gap 0.6-0.7mm (.023″.028″)
  • Fastening torque =145-155kg.cm(125-135in.lb)
