The string head or blade will rotate during carburetor adjustments.
It has been reported that vibrations from hand-held tools may contribute to a
condition called Raynaud’s Syndrome in certain individuals. Symptoms may include
tingling, numbness and blanching of the fingers, usually apparent upon exposure
to cold. Hereditary factors, exposure to cold and dampness, diet, smoking and
work practices are all thought to contribute to the development of these symptoms.
It is presently unknown what, if any, vibrations or extent of exposure may contribute
to the condition. There are measures that can be taken by the operator to possibly
reduce the effects of vibration:
Keep your body warm in cold weather. When operating the unit, wear gloves to
keep the hands and wrists warm. It is reported that cold weather is a major factor
contributing to Raynaud’s Syndrome.
After each period of operation, exercise to increase blood circulation.
Take frequent work breaks. Limit the amount of exposure per day.
If you experience any of the symptoms of this condition, immediately discontinue use
and see your doctor about these symptoms.
Keep the tool well maintained, fasteners tightened and worn parts replaced.
Mix and store fuel in a container approved for fuel.
Mix fuel outdoors where there are no sparks or flames. Wipe up any fuel spillage.
Move 9 m away from refueling site before starting engine.
Stop the engine and allow to cool before refueling, performing adjustments or
maintenance or storing the unit.
Allow the engine to cool; empty the fuel tank and secure the unit from moving
before transporting in a vehicle.

FOR TRIMMER
Replace string head if cracked, chipped or damaged in any way. Be sure the string
head or blade is properly installed and securely fastened. Failure to do so can
cause serious injury.
Make sure all guards, straps, deflectors and handles are properly and securely
attached.
Use only the manufacturer's replacement line in the cutting head. Do not use any
other cutting attachment.
Never operate unit without the grass deflector in place and in good condition.
Maintain a firm grip on both handles while trimming. Keep string head below waist
level. Never cut with the string head located more than 76 cm above the ground.
FOR BRUSHCUTTER AND BLADE
After engine stops, keep rotating blade in heavy grass or pulpy weeds until it stops.
Do not operate the brushcutter unless the blade guard is firmly secured in place
and in good condition.
Use heavy gloves while installing or removing blades.
Always stop the engine and remove the spark plug wire before attempting to
remove any obstruction caught or jammed in the blade or before removing and
installing the blade.
Do not attempt to touch or stop the blade when it is rotating.
A coasting blade can cause injury while it continues to spin after the engine is
stopped or throttle trigger released. Maintain proper control until the blade has
completely stopped rotating.
Replace any blade that has been damaged. Always make sure blade is installed
correctly and securely fastened before each use. Failure to do so can cause serious
injury.
Useonlythemanufacturer'sreplacementbladeintendedforuseonthisbrushcutter.
Do not use any other blade.
The blade is suited for cutting pulpy weeds and vines only. Do not use for any other
purpose. Never use the blade to cut woody brush.
Exercise extreme caution when using the blade with this unit. Blade thrust
is the reaction that may occur when the spinning blade contacts anything
it cannot cut. This contact may cause the blade to stop for an instant, and
suddenly “thrust” the unit away from the object that was hit. This reaction

can be violent enough to cause the operator to lose control of the unit.
Blade thrust can occur without warning if the blade snags, stalls or
binds. This is more likely to occur in areas where it is difficult to see the
material being cut. For safety and ease of cutting, approach the weeds
being cut from the right to the left. In the event an
unexpected object or woody stock is encountered,
this could minimize the blade thrust reaction.
Never cut any material over 13 mm in diameter.
Always wear the shoulder strap when using the brushcutter and adjust to a
comfortable operating position. Maintain a firm grip on both handles while cutting
with a blade. Keep the blade away from the body and below waist level. Never use
the brushcutter with the blade located 76 cm or more above ground level.
Cover the blade with the blade protector before storing the unit or during
transportation. Always remove the blade protector before using the unit.
If not removed, the blade protector could become a thrown object as the blade
begins to turn.
