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,
followed by loss of colour and numbness in the fingers. The following precautions are strongly recommended be-
cause 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, con-
sult 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 sore-
ness, 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
If the cutting attachment rotates even though the throttle trigger is in the idle speed position when the engine is start-
ed, adjust the carburettor before using the product.
Do not start or operate unit unless all guards and protective covers are properly assembled to unit.
Never reach into any opening while the engine is running. Moving parts may not be visible through openings.
Moving parts can amputate fingers or cause severe injuries. Keep hands, clothing and loose objects away from all
openings.
Always stop engine, disconnect spark plug, and make sure all moving parts have come to a complete stop before
removing obstructions, clearing debris, or servicing unit.
Keep a solid stance
Maintain footing and balance at all times. Do not stand on slippery, uneven or unstable surfac-
es. Do not work in odd positions or on ladders. Do not overreach.
Operate the product only from the ground or out of an approved bucket lift.
Always evaluate the branches to be pruned for hazards such as loose dead branches which
may fall and strike the operator or helpers. Remove hazards before pruning.
Plan retreat path from falling objects.
Cut branches bounce when striking ground.
Check that shoulder harness is adjusted for safe, comfortable operation.
Turn the product off when moving from tree to tree.
Avoid any contact with saw chain.
Failure to observe these precautions could cause serious injury.
When transporting the unit, empty the fuel tank, install the guide bar cover, put the unit in an upright position, and
secure it firmly.
Failure to do so could result in damage or injury.
Never attempt to operate the product with one hand.
Ensure that you hook your thumbs around the grips, wrapping them in your
thumb and remaining fingers.
Kickback
Kickback can lead to dangerous loss of control of the product and result in serious in-
jury to the operator or any one standing close by. Hold the product firmly with both
hands with thumbs and fingers encircling the front and rear handles. Be aware of the
down and outward path the pruner will take after the cut is made.
Kickback may occur when the moving saw chain at 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. In some cases
this may cause a lightning-fast reverse action, kicking the guide bar and saw chain up and
back or down and back towards the operator. Either of these reactions may cause the oper-
ator to lose control of the product which could result in serious personal injury.
With a basic understanding of kickback, you can reduce or eliminate the element of surprise
which contributes to accidents.
Avoid contact of the guide bar tip with any object while the saw chain is moving.
Cut only wood. Avoid striking concrete, metal, wire, or other obstructions which could cause kickback or damage to the
saw chain.
If the saw chain does strike a foreign object, immediately stop the engine, inspect and repair the product if necessary.

17
Pruning operation
Pruning techniques
Plan cut carefully. Check direction branch will fall.
Plan retreat path from falling branch. Cut branches bounce
when striking ground.
Long branches should be removed in several pieces.
Do not stand directly beneath branch being cut.
When ready to cut: Hold "cutting shoe" against branch. This
will prevent whipping of the branch. Do not use back and forth
sawing action.
Look out for branch immediately behind the branch being cut.
If saw chain hits rear branch damage to saw chain may occur.
Accelerate to full throttle.
Apply cutting pressure.
Ease cutting pressure when nearing end of cut to maintain
control.
When pruning a limb 102 mm diameter or larger cut as follows:
(1) Under cut 1/4 limb diameter near tree trunk.
(2) Finish top cut slightly farther out on limb.
(3) Flush cut stub at trunk.
Do not use for felling or bucking.
Check that the cutting attachment, guide bar, and saw chain is firmly attached and in safe operating condition.
Use only one YAMABIKO-approved extension on the pruner.
Do not hit rocks, stones, tree stumps, and other foreign objects with the saw chain.
Do not cut into the ground with the saw chain.
If cutting attachment end strikes an obstruction, stop engine immediately and inspect saw chain for damage.
Do not operate with a dull, fractured, or discolored saw chain.
