8
General operation
Do not run the engine indoors, or where there is poor ventilation.
Engine fumes contain deadly poisonous carbon monoxide.
Do not operate with a worn or damaged cutting attachment.
Do not run engine at full throttle without a load.
Do not hit rocks, stones, tree stumps, and other foreign objects with the cutting attachment.
If cutting attachment strikes an obstruction, stop engine immediately and inspect cutting
attachment for damage.
Start on ground with cutting attachment in the clear.
Lay the unit down on a clear area and set the controls for starting.
Be sure the cutting attachment cannot contact the ground or any obstruction.
Hold the unit firmly down so you will not lose control during starting.
Do not start the unit in the air, or from the harness.
The unit could swing into your leg or an obstruction if you lose control.
Do not raise the cutting attachment above knee height.
If raised higher, the cutting attachment will be more directly in line with your face.
Thrown objects may hit your face and eyes.
Wear the recommended protectiive gear.
Never operate the unit without the proper guards, shoulder harnes and other protective
devices.
Never operate the unit without good visibility and light.
Do not allow anyone to enter the operating danger zone with you.
The danger zone is an area of 15 m in radius.
Insist that persons in the risk zone beyond the danger zone wear eye protection to protect
them from thrown objects.
If the unit must be used where there are unprotected people, operate at a low throttle speed
to reduce the risk.
Ensure that there are no children, bystanders, and pets in the work area.
Keep all children, bystanders and fellow workers outside 15 m radius for grass trimmers /
brushcutters.
WARNING
Eye protection should be considered for everyone in the zone of risk.
Risk of eye injury diminishes with distance.
9
Stop the engine before leaving the machine, children are not allowed to use the machine, stop
the machine between different working places.
If you are approached, stop the engine and cutting attachment immediately.
Keep your hands and body away from silencer to prevent heat injury while the engine is hot.
Sudden vibration?
Shut down immediately!
Shut down immediately if the unit starts to shake or vibrate.
A sudden vibration is a sign there may be dangerous trouble, such as a broken flywheel, clutch
or cutting attachment, or loose parts.
Do not use the unit until the problem has been properly diagnosed and corrected.
Keep feet and hands away until rotation stops.
When the unit is turned off, make sure the cutting attachment stops before the unit is set down.
If the cutting attachment rotates after throttle is returned to idle, carburettor adjustment is
required.
Follow instruction on this Manual to make the adjustment yourself, or have the carburettor
adjusted by your shindaiwa dealer.
All maintenance and adjustments given in this Manual should be performed by you or your
shindaiwa servicing dealer on a timely basis.
All required service or repair must be done only by shindaiwa servicing dealer.
Never attempt to use an incomplete or one fitted with unauthorized modification.
Do not operate one-handed.
Always use both hands on the handles.
Always hold the unit with the fingers and thumbs encircling the handles.
10
Vibration and cold
It is believed that a condition called Raynaud's Phenomenon, which affects the fingers of
certain individuals, may be brought about by exposure to cold and vibration.
Exposure to cold and vibration may cause tingling and burning followed by loss of color 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 further exposing yourself to cold and vibration.
Repetitive stress injuries
Painful or numb fingers?
See your doctor immediately!
It 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 repetitive stress injury, 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 the hand and arm muscles.
See a doctor if you feel tingling, numbness or pain in the fingers, hands, wrists or arms.
The sooner RSI is diagnosed, the more likely permanent nerve and muscle damage can be
prevented.
11
Rules for safe operation with metal blade
Use correct blade
1. Blade. 2. Safety clip. 3. Lower blade retainer. 4. Bolt guard. 5. Bolt.
Inspect blades before use.
Wires can catch and flap around
Always use the blade suited for the job.
Do not hit rocks, stones, tree stumps, and other foreign objects with the blade.
Do not cut into the ground with the blade.
If blade strikes an obstruction, stop engine immediately and inspect blade for damage.
Do not operate with a dull, bent, fractured or discoloured blade and worn or damaged nut.
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.
Scything weeds
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.
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.
Injury can occur if a jam is removed and the cutting attachment suddenly starts.
WARNING
Serious injury may result from the improper use of blades.
Read and comply with all safety instructions listed in this Manual.
The metal blade is designed especially to cut weeds and grass.
To avoid injury due to kickback or blade fracture, do not use the metal blade to cut
brush or trees.
Use only cutting attachments recommended by shindaiwa.
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 misuse or improper sharpening.
12
Reaction forces
1. 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.
2. 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.
Kickback
This may occur when the moving blade at the front of the blade circle contacts strong brush or
trees.
The force that occurs pushes the entire unit and blade violently away in an arc.
Kickback is a danger to a bystander and also a jolting force to the operator.
Blade selection
Plastic grass / weed blade may be used wherever the nylon line head is used.
Do not use this blade for heavy weeds or brush!
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, 2 cm diameter or larger.
80 tooth brush blade is designed for cutting brush and woody growth up to 2 cm diameter.
22 tooth clearing blade is designed for dense thickets and saplings up to 6.5 cm diameter.
WARNING
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.
WARNING
Use only shindaiwa approved attachments.
Serious injury may result form the use of a non-approved attachment combination.
shindaiwa will not be responsible for the failure of cutting devices, attachments or
accessories which have not been tested and approved by shindaiwa.
Read and comply with all safety instructions listed in this manual.
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.
13
Rules for safe operation with nylon line cutting head
Use correct cutting attachment
Operate the machine with its throttle trigger fully grasped for higher engine speed.
Do not give an excessive load to the spinning cutting head to stop.
In case of cutting the thick grass, cut the grass little by little so as to maintain engine speed.
When the rotation of the cutting head stops during operation, immediately release the
throttle trigger to lower the engine speed, pull the machine away from the grass, and fully
grasp the throttle trigger and rotate the cutting head to continue cutting.
Stop the engine immediately when grass or cord / string like object wound around the
cutting head, and take them off before starting the engine.
The basic cutting actions pictured are: Trimming, scything, scalping and lawn edging.
These actions are as follows:
Trimming
1. Angle to wall. 2. Debris. 3. Knife side raised. 4. Angle to ground.
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 line 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 to 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 cutter 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 line 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.
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.
Injury can occur if a jam is removed and the cutting attachment suddenly starts.
WARNING
Serious injury may result from the improper use of cutting attachment.
Read and comply with all safety instructions listed in this Manual.
Use only flexible, non-metallic line recommended by shindaiwa.
Use only cutting attachments recommended by shindaiwa.
Excessive nylon line beyond cut off knife could fly off when the nylon line cutter
starts rotating after adjustment of nylon line length.
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.
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.
14
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 bare.
Edging is trimming the grass back where it has spread over a pavement or driveway.
During both edging and scalping, 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.
Nylon line head or disc rotates anticlockwise.
The knife will be on the left side of the shield.
1. Cut on this side. 2. Debris.
For nearly all cutting, it is good to tilt the nylon cutter 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 cutter 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.

Maintenance and care
If you have any questions or problems, please contact your shindaiwa dealer.
Cleaning air filter
1. Three screws. 2. Air cleaner cover. 3. Air filter.
Close choke.
Loosen three screws and remove air cleaner cover first, and then air filter.
Brush dirt from filter or wash it in a suitable cleaner.
Dry it completely before installation.
Reinstall the air filter and air cleaner cover, and then tighten three screws.
Check fuel system
Check before every use.
After refuelling, make sure fuel does not leak or exude from around fuel pipe, fuel grommet
or fuel tank cap.
In case of fuel leakage or exudation there is a danger of fire.
Stop using he machine immediately and request your dealer to inspect or replace.
Replacing fuel filter
1. Fuel tube. 2. Fuel filter.
Drain all the fuel from the fuel tank.
Pull apart the fuel tube at the joint and remove the fuel filter to clean or replace as
necessary.
Check spark plug
∗ Spark plug gap: 0.6 to 0.7 mm
Check plug gap.
Correct gap is 0.6 to 0.7 mm.
Inspect electrode for wear.
Inspect insulator for oil or other deposits.
Replace plug if needed and tighten to 15 - 17 N•m (150 to 170 kgf•cm).
Cooling system maintenance
1. Cylinder fins. 2. Air intake.
Remove dust and dirt from between fins.
Before each use, remove accumulated debris from bottom engine intake grille.
NOTE
If filter is excessive dirty or no longer fits properly, replace it.
IMPORTANT
To maintain proper engine operating temperature, cooling air must pass freely through the
cylinder fin area.
This flow of air carries combustion heat away from the engine.
Overheating and engine seizure can occur when:
Air intakes are blocked, preventing cooling air from reaching the cylinder,
or
Dust and grass build up on the out side of the cylinder.
This build-up insulates the engine and prevents the heat from leaving.
Removal of cooling passage blockages or cleaning of cylinder fins is considered "Normal
Maintenance".
Any resultant failure attributed to lack of maintenance is not warranted.
