For safe use of your product
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 vibration and cold. Exposure to vibration and cold may cause tingling and burning, fol-
lowed 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 injuries
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 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 diag-
nosed, the more likely permanent nerve and muscle damage can be prevented.
Failure to observe these instructions could result in damage to your health.
WARNING
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.
11
For safe use of your product
Precautions concerning the cutting attachment
1.With metal blade
2.With nylon line cutting head
Kickback
The phenomenon that occurs if the trimmer blade comes into con-
tact 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 en-
sure 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.
WARNING
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.
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.
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.
Use only cutting attachments recommended by YAMABIKO CORPORATION.
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.
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 adjust-
ment of nylon line length.
Failure to do so could lead to an accident or injury.
12
For safe use of your product
Protective gear
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.
WARNING
CAUTION
Use only flexible, non-metallic line recommended by YAMABIKO CORPORATION.
WARNING
Wear protective gear
Always wear the following protective gear when working with the trimmer.
1. Head protection (helmet): Protects the head
2. Ear muffs or ear plugs: Protect the hearing
3. Safety goggles: Protect the eyes
4. Face shield: Protects the face
5. Safety gloves: Protect the hands from cold and vibration
6. Work clothes that fit (long sleeves, long trousers): Protect the body
7. Heavy duty, non-slip protective boots (with toecaps) or non-slip work shoes
(with toecaps): Protect the feet
8. Shin guards: Protect the legs
Failure to observe these precautions could result in damage to your sight or hearing, or
lead to a serious injury.
When necessary, please use the protective gear below.
Dust mask: Protects the breathing apparatus
Bee net: To deal with attacks by bees
Wear proper clothing.
Do not wear ties, jewellery, or loose, dangling clothing which could be caught in the unit.
Do not wear open toed footwear, or go bare-foot or barelegged. In certain situations, total
face and head protection may be required. For heavy brush cutting with metal blade, log-
ger's trousers or leg chaps with protective inserts are added considerations.
Failure to observe these precautions could result in damage to your sight or hearing, or lead
to a serious injury.

WARNING
Do not attempt to fit the trimmer blade with one hand or without using the socket spanner. Fit the trimmer blade ac-
curately using the supplied socket spanner and tighten firmly in position.
The trimmer must not be used if the blade vibrates or is loose.
Wear heavy duty gloves when working with the trimmer blade. When replacing the trimmer blade during a trimming
task, ensure that the engine is switched off and that the blades have stopped.
Do not use any tools other than the proved socket spanner to tighten the blade, a pneumatic or electric tool may
tighten the blade more than necessary and cause the nut or the output shaft to break.
When turning the product over to replace the trimmer blade, ensure that the fuel tank cap is securely in place.
Failure to do so could lead to an injury or serious accident, or cause a fire.
