For safe use of your product

WARNING

Vibration and coldIt is believed that a condition called Raynaud's Phenomenon which affects the fingers of certain individuals may be brought about by exposure to vibration and cold. Exposure to vibration and cold may cause tingling and burning, followed by loss of colour and numbness in the fingers. The following precautions are strongly recommended because the minimum exposure which might trigger the ailment is unknown.○ Keep your body warm, especially the head and neck, feet and ankles, and hands and wrists.○ Maintain good blood circulation by performing vigorous arm exercises during frequent work breaks, and also by not smoking.○ Limit the number of hours of operation. Try to fill each day with jobs where operating the trimmer or other hand-held power equipment is not required.○ If you experience discomfort redness and swelling of the fingers, followed by whitening and loss of feeling, consult your physician before exposing yourself further to cold and vibration.Failure to observe these instructions could result in damage to your health.

Repetitive stress injuriesIt is believed that over-using the muscles and tendons of the fingers, hands, arms and shoulders may cause soreness, swelling, numbness, weakness and extreme pain to the areas just mentioned. Certain repetitive hand activities may put you at a high risk for developing a repetitive stress injury (RSI). To reduce the risk of RSI, do the following:○ Avoid using your wrist in a bent, extended or twisted position.○ Take periodic breaks to minimize repetition and rest your hands. Reduce the speed and force in which you do the repetitive movement.○ Do exercises to strengthen hand and arm muscles.○ See a doctor if you feel tingling, numbness or pain in your fingers, hands, wrists or arms. The sooner RSI is diagnosed, the more likely permanent nerve and muscle damage can be prevented.Failure to observe these instructions could result in damage to your health.

Proper training

Do not permit operation without proper training and protective equipment.

Be thoroughly familiar with the controls and proper use of unit.

Know how to stop the unit and shut off the engine.

Know how to unhook a harnessed unit quickly.

Never allow anyone to use the unit without proper instruction.

WARNING

Remove foreign objects and obstructions before working with the product ○ Before starting work, check the area where you will be working and remove any small stones and empty cans likely to ricochet off the cutting attachment, as well as any pieces of string or wire that might become twisted around the cutting attachment. ◆ An accident or serious injury can occur if foreign objects ricochet off the cutting attachment or wire and other materials twisted round the product spring off it.

Do not hold the cutting attachment up when working with the product ○ Do not hold the cutting attachment up while you work. You must not work with the cutting attachments raised above knee level. ◆ Raising the cutting attachment above knee level brings the plane of rotation closer to the face, and any objects that fly off the cutting attachments could cause an accident or serious injury.

Turn off the engine immediately if anything goes wrong In the following situations, turn off the engine immediately and ensure that the cutting attachments have stopped before checking each area of the product. Replace any damaged parts. ○ If the cutting attachment hits a rock, tree, post, or other such obstruction while you work. ○ If the product suddenly starts to vibrate abnormally. ◆ Continuing to use parts when they are damaged could lead to an accident or serious injury.

WARNING

Kickback

The phenomenon that occurs if the trimmer blade comes into contact with a tree, post, rock or other hard object while rotating at high speed and reacts by recoiling powerfully and instantaneously is known as kickback.
Causing kickback can result in a loss of control over the product and is highly dangerous.
In particular, if the front-right quadrant of the trimmer blade (B) strikes a shrub or other such object, the trimmer blade will cause the product to recoil sharply backwards to the right.
To prevent kickback, do not trim from left to right. Be careful to ensure that the trimmer blade does not strike any hard objects.
- When trimming, ensure that the object you are cutting meets the portion of the blade 1/3 in from the front edge on the left-hand side (A).
Failure to do so could cause an injury or fatal accident.

Precautions concerning the cutting attachment

DANGER

Always stop the engine when a cutting attachment jam occurs. Do not attempt to remove an object causing a jam if the engine is running. Severe injury can occur if a jam is removed and the cutting attachment suddenly starts.

1.With metal blade

WARNING

Use correct blades

Serious injury may result from the improper use of blades. Read and comply with all safety instructions listed in this manual.
Use only cutting attachments recommended by YAMABIKO Corporation.
The type of blade used must be matched to the type and size of material cut. An improper or dull blade can cause serious personal injury. Blades must be sharp. Dull blades increase the chance of kick-out and injury to yourself and bystanders.

• Plastic/Nylon Grass/Weed Blades may be used where ever the nylon line head is used. Do not use this blade for heavy weeds or brush.
• The 3 cutter blade is designed especially to cut weeds and grass. To avoid injury due to kickback or blade fracture, do not use the 3 cutter blade to cut brush or trees.
• 8 Tooth Weed/Grass Blade is designed for grass, garden debris and thick weeds. Do not use this blade for brush or heavy woody growth, 19mm diameter or larger.
• 80 Tooth Brush Blade is designed for cutting brush and woody growth up to 13mm diameter.
  22 Tooth Clearing Blade is designed for dense thickets and saplings up to 64mm diameter.

Damaged or shattered blades can cause accidents and serious injury.

Inspect blade before use

Pieces from a cracked metal blade can fly off during operation. Inspect metal blades for cracks before each use. Discard cracked blades no matter how small the crack. Cracked blades can be the result of the misuse or improper sharpening.
Damaged or shattered blades can cause accidents and serious injury.

Reaction forces

Be sure you understand the reaction forces of push and pull, and kickback described in this manual, and how these forces may affect your balance in the operation of a unit.

Failure to do so could cause an injury or fatal accident.

For safe use of your product

2.With nylon line cutting head

WARNING

Use correct cutting attachment ○ Serious injury may result from the improper use of cutting attachment. Read and comply with all safety instructions listed in this manual. ○ Use only cutting attachments recommended by YAMABIKO Corporation. ○ Use only nylon line cutting head. Do not use any type of metal blade. ◆ Failure to do so could lead to an accident or serious injury.

Excessive nylon line beyond cut off knife could fly off when the nylon line cutting head starts rotating after adjustment of nylon line length. ◆ Failure to do so could lead to an accident or injury.

Do not trim near cars or pedestrians Use extreme caution when operating over bare spots and gravel, because the line can throw small rock particles at high speeds. The shield on the unit cannot stop objects which bounce or ricochet off hard surfaces. ◆ Failure to do so could lead to an accident or serious injury.

Avoid wire Do not trim in any area where there are broken strands of fencing wire. Remove the broken pieces of wire, or give the area wide berth. Wear proper safety protection. Do not cut where you cannot see what the cutting device is cutting. ◆ Failure to do so could lead to an accident or serious injury.

1. Emergency tab

2. Never attempt to operate the product with one hand.

3. Ensure that you hook your thumbs around the grips, wrapping them in your thumb and remaining fingers.

Always mount the trimmer correctly using the shoulder harness.
- The shoulder harness is fitted with an emergency release function. In case of emergency, strongly pull the emergency tab at the hook. The machine will be released from the strap.

Basic trimming operation with nylon line cutting head Adjusting nylon line

Engine operating speeds

• Cut off knife on the shield adjusts cutting swath automatically by cutting nylon lines evenly when attachment starts rotating.
• When operating with less than maximum cutting swath, cut two nylon lines in equal lengths.
• To advance trimmer line, tap the nylon line cutting head (A) against the ground while the head is turning at normal operating speed.

Operate the unit at full throttle while cutting grass.

CAUTION

Operation of trimmer without a cutting attachment shield and using excessive line length can lead to premature clutch failure.
Operation at low speeds can lead to premature clutch failure.

The basic cutting actions

The basic cutting actions pictured are: Trimming, scything, scalping and lawn edg These actions are as follows:

1. Angle to wall

2. Knife side raised

3. Debris

4. Angle to ground

A: Scalping B: Edging

Nylon line cutting head rotates anticlockwise.

The knife will be on the left side of the shield.

1. Debris
2. Cut on this side

Trimming

This is feeding the trimmer carefully into the material you wish to cut. Tilt the head slightly to direct the debris away from you. If cutting up to a barrier such as a fence, wall or tree, approach from an angle where any debris ricocheting off the barrier will fly away from you.

Move the nylon line cutting head slowly until the grass is cut right up to the barrier, but do not jam (overfeed) the line into the barrier. If trimming up wire mesh or chain link fencing, be careful to feed only up to the wire. If you go too far, the line will snap off around the wire.

Trimming can be done to cut through weed stems one at a time. Place the nylon line cutting 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, just use the very end of the line to wear through the stem slowly.

Scything

This is the cutting or mowing of large grassy areas by sweeping or swinging the trimmer in a level arc. Use a smooth, easy motion. Do not try to hack or chop down the grass. Tilt the nylon line cutting head to direct the debris away from you on the scything stroke. Then return without cutting grass for another stroke. If you are well protected and do not care whether some debris is thrown in your direction, you may scythe in both directions.

Scalping and edging

Both of these are done with the nylon line cutting head tilted at a steep angle. Scalping is removing top growth, leaving the earth bare. Edging is trimming the grass back where it has spread over a pavement or driveway. During both edging and scaling, hold the unit at a steep angle in a position where the debris, and any dislodged dirt and stone, will not come back towards you even if it ricochets off the hard surface.

Although the pictures show how to edge and scalp, every operator must find for himself the angles which suit his body size and cutting situation.

For nearly all cutting, it is good to tilt the nylon line cutting head so that contact is made on the part of line circle where the line is moving away from you and the shield (See appropriate picture). This results in the debris being thrown away from you.

Tilting the head to the wrong side will shoot the debris toward you. If the nylon line cutting head is held flat to the ground so that cutting occurs on the whole line circle, debris will be thrown at you, drag will slow the engine, and you will use up a lot of line.

Do not trim near cars or pedestrians.

Always wear proper eye protection against thrown objects. Objects can bounce up at you from the ground under the shield, or ricochet off any nearby hard surface.

Do not trim at high speed near roadways when there is traffic, or in places where there are pedestrians. If you must trim where people are in the zone of risk use a much lower or reduced speed, by using a partial trigger setting. Do not use full throttle.

Line pushed into wire fencing will snap off.

Do not push the line into tough weeds, trees, or wire fences. Pushing the line into chicken wire, chain link fencing or thick brush can result in snapped-off line ends being hurled back at the operator. The proper way is to cut right up to a barrier, such as any of those mentioned, but never run the line into or through the obstruction. Do not cut closely to obstruction or barrier.

Avoid wire

Avoid nylon line contact with broken wire fencing. Pieces of wire broken off by the trimmer can be hurled at high speeds.

Basic trimming operation with metal blade

WARNING

Please observe the following instructions when trimming.

Ensure that the trimmer blade does not come into contact with hard obstructions such as stone, metal, or concrete.
If the blade hits an obstruction, turn off the engine immediately and ensure that the blade has stopped before checking the blade and shield for damage.
Never use cracked blades, as they could fly off while you are working.
Check to ensure that the trimmer blade has been tightened securely in place.
Replace the shield if it is damaged or cracked.
Replace the trimmer blade nut when it becomes worn.
Failure to do so could lead to an accident or serious injury.

Engine operating speeds

Operate the engine at full throttle while cutting. Best fuel efficiency is obtained by releasing the throttle when swinging back after a cut.

• To prevent possible engine damage, do not allow the trimmer or brushcutter to run at high speeds without a load.
• Avoid operating the attachment at low speeds. Doing so can lead to rapid clutch wear. In addition, slow-speed operation tends to cause grass and debris to wrap around the cutting attachment.

Use correct blade

Inspect blades before use
Wires can catch and flap around

Scything weeds

Reaction forces

Anticlockwise rotation

1. Push
2.Pull

Always use the blade suited for the job.
- Do not allow the trimmer blade to come into contact with hard obstructions such as stone, concrete or metal.
- Do not cut into the ground with the blade.
- If the blade hits an obstruction, turn the engine off immediately and ensure that the trimmer blade has stopped rotating before checking the blade and shield for damage.
- Do not operate with a dull, bent, fractured or discoloured blade and worn or damaged nut.
- Never use a cracked trimmer blade as it could shatter off while you are working.
- Do not run engine at full throttle without a load.
- Remove all foreign objects from work area.
- Do not operate brushcutter without shoulder harness and shield.

This is cutting by swinging the cutting attachment in a level arc. It can quickly clear areas of field grass and weeds. Scything should not be used to cut large, tough weeds or woody growths.

If a sapling or shrub binds the cutting attachment, do not use the cutting attachment as a lever to free the bind, because this will cause cutting attachment failure.

Instead, shut off the engine and push the sapling or shrub to free the blades.

Do not use a cracked or damaged blade.

Push.

The operator may feel the unit push toward him when he tries to cut the object on right. If he cannot hold the blade in the cut, a kickback may occur when the blade is pushed out to where the teeth at the outside furthest point from the operator are cutting. The blade will "kickback" sideways.

Pull.

The opposite of push. When object on left, the operator may feel the unit pull away. Although this pull type of cutting may cause sawdust to be thrown back at the operator, it is recommended for sawing off heavy brush because the cutting is smoother and more stable than when the unit pushes.

Trimming operation

Kickback

Precautions to observe when working

Kickback.

If you hit a hard object with the front-right of the trimmer blade, such as when trimming in both directions, the blade will kick sharply back to the right. This is a phenomenon known as "kick back", and can cause a serious accident due to the operator losing control over the product. Take particular care to ensure that you do not strike any hard object with the front-right of the trimmer blade.

• The area within a radius of 15m of the product is a danger zone. Make sure that there are no children, onlookers, or pets in this zone. If anyone comes within 15m , turn off the engine immediately to stop the blade from rotating.

• If someone is helping you with the work or you are working together, identify the way in which you will signal to each other and work at least 15m apart. You are advised to carry a whistle in case you need to communicate.

• Turn off the engine immediately if the product suddenly starts to vibrate abnormally. Sudden vibration may be caused by a problem with a component such as the flywheel, clutch, or trimmer blade, or by a loose screw or other such factor. Do not use the product until you have identified the cause of the problem and the repair has been completed.

• The trimmer blade could fly off unless tightened securely. Ensure that it is fitted securely in place.

• Replace the shield if it is damaged or cracked.

• If you work with the angle transmission in contact with the surface of the ground, the trimmer blade nut and cup can easily become worn. Replace them with new parts if this happens.

• When you turn off the engine, check to ensure that the trimmer blade has stopped rotating before you lower the product to the ground. Even if the engine has been turned off, the blade can still cause an injury while free-wheeling.

• The silencer will remain hot for some time after the engine has been turned off. Carry the product with the silencer away from you to avoid touching it with your body.

• When carrying the product, always turn the engine off and fit the trimmer blade cover over the trimmer blade.

WARNING

Before performing any maintenance, repair, or cleaning work on your unit, make sure the engine and cutting attachment are completely stopped. Disconnect the spark plug wire before performing service or maintenance work.
Never repair a damaged blade by welding, straightening, or by modifying its shape. An altered blade may break during operation, resulting in serious personal injury.

CAUTION

Make sure you do not pierce the fuel line with the end of the hooked wire. The line is delicate and can be damaged easily.

WARNING

Never operate the unit with a damaged or missing silencer or spark arrester! Operating with a missing or damaged spark arrester is a fire hazard and could also damage your hearing.

• Carbon deposits in silencer will cause a drop in engine output and overheating. Spark arrester screen must be checked periodically. Clean deposits from silencer.

IMPORTANT

Do not remove the silencer cover. If necessary, Please consult your dealer.

Carburettor adjustment

WARNING

YOU MAY ADJUST THE IDLE SPEED ONLY by turning the idle speed adjustment screw (T).
During carburettor adjustment, the cutting attachment may move. Pay utmost attention and care to the cutting attachment so as not to get injured by the moving cutter.
- When carburettor adjustment is completed, the cutting attachment should not move at idle speed, otherwise serious personal injury may result.
You must NOT carry out any Carburettor adjustment, other than the idle speed. All other adjustments MUST be performed by an authorized service dealer, or serious personal injury may result due to malfunction of the engine.

CAUTION

• When there is trouble with the carburettor, contact an authorized service dealer.

T: Idle speed adjustment screw

Every unit is test run at the factory and the carburettor is fine tuned for maximum performance.

Before adjusting carburettor, clean or replace air filter, start engine and run several minutes to bring it to operating temperature. The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment.

To adjust the carburettor proceed as follow:

1. Place the unit on the ground, then start the engine, and then allow it to idle 2-3 minutes until warm.
2. If the attachment moves when the engine is at idle, reduce the idle speed by turning the idle adjustment screw(T) counter-clockwise.
3. Repeat the process of accelerating to full throttle and return to idle a few times. Check that the cutting attachment stops moving at idle.
4. If a tachometer is available, the engine idle speed should be final adjusted to the settings recommended in the Specifications section.

NOTE

When the carburettor cannot be adjusted properly with the idle speed adjustment screw (T), you must contact an authorized service dealer.

Checking the blade

• Use only blade designated for this model by the manufacturer.
• When a crack is noticed on the blade, do not use it but replace with a new one.
• Ensure that the blade is correctly fitted in accordance with the instructions.

Loading nylon line

1. Wear Indicators

Long term storage

• When the cutting blade becomes dull due to wear, reverse it for further use.
• When chip or bend occurs on the blade, vibration will increase. Replace with new one.

• When filing the blade file 3 cutting edges evenly using a flat file as shown in the illustration. Otherwise, the balance will be lost and vibration will increase.

• Cut one piece of line to recommended length.
  2.4 mm dia. -6 m

• Align arrows on top of knob with openings in eyelets.
• Insert one end of nylon line into an eyelet, and push line equal distance through nylon line cutting head.
• Hold nylon line cutting head while turning knob clockwise to wind line onto spool until about 13cm of each line remains exposed.

IMPORTANT

When the wear indicators located at the bottom of the nylon line cutting head are worn smooth, replacement of the cover or the entire nylon line cutting head is required.

Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage.

• Clean external parts thoroughly and apply a light coating of oil to all metal surfaces.
• Drain all the fuel from the carburettor and the fuel tank.

To remove the remaining fuel from the fuel lines and carburettor and with the fuel drained from the fuel tank.

1. Prime the primer bulb until no more fuel is passing through.
2. Start and run the engine until stops running.
3. Repeat steps 1 and 2 until the engine will no longer start.

NOTE

All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL.
Gasoline stored in the carburettor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs.

• Remove the spark plug and pour about 7 grams of 2-stroke engine oil into the cylinder through the spark plug hole. Place a clean cloth over the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug. (Do not connect the spark plug cap.)
• Before storing the unit, repair or replace any worn or damaged parts.
• Remove the air cleaner element from the carburettor and clean it thoroughly with soap and water. Let dry and reassemble the element.
• Store the unit in a clean, dust free area.
