SAFETY

■■

■ Inspect the unit before each use for loose fasteners, fuel

leaks etc. Replace any damaged parts before use.

■■

■ The string head or blade will rotate during carburettor

adjustments.

■■

■ It has been reported that vibrations from hand-held tools

may contribute to a condition called Raynaud’s Syn-

drome 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 not known at

present 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:

a) Keep your body warm in cold weather. When operat-

ing 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.

b) After each period of operation, exercise to increase

blood circulation.

c) Take frequent work breaks. Limit the amount of

exposure per day.

d) Keep the tool well maintained, fasteners tightened

and worn parts replaced.

If you experience any of the symptoms of this condition,

immediately discontinue use and see your doctor about

these symptoms.

■■

■ Mix and store fuel in a container approved for petrol.

■■

■ Mix fuel outdoors where there are no sparks or flames.

Wipe up any fuel spillage. Move 9 m (30 ft) away from

refuelling site before starting engine.

■■

■ Stop the engine and allow to cool before refuelling or

storing the unit.

■■

■ Allow the engine to cool; empty the fuel tank and secure

the unit from moving before transporting in a vehicle.

SPECIFIC SAFETY RULES FOR TRIMMER USE

■■

■ 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 string 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 over 76 cm (30 in) or more above

the ground.

SPECIFIC SAFETY RULES FOR BRUSHCUTTER AND

BLADE USE

■■

■ 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 sparking plug

wire before attempting to remove any obstruction caught

or jammed in the blade or before removing and install-

ing 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 damaged blade. Always make sure blade

is installed correctly and securely fastened before each

use. Failure to do so may cause serious injury.

■■

■ Use only the manufacturer’s replacement TRI-ARC

blade intended for use on this brushcutter. Do not use

any other blade.

■■

■ The TRI-ARC blade is suited for cutting pulpy weeds

and vines only. Do not use for any other purpose. Never

use the TRI-ARC blade to cut woody brush.

■■

■ Exercise extreme caution when using the blade with this

unit. Blade thrust is the reaction which 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 may

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 cutting ease and safety,

approach the weeds being cut from the right to the left.

In the event that an unexpected object or woody stock is

encountered, this could minimise the blade thrust

reaction.

■■

■ Never cut any material over 13 mm (1/2 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 body

and below waist. Never use the brushcutter with the

blade located 76 cm (30 in) or more above the

ground level.

■■

■ Cover the blade with the blade protector before storing

the unit or during transport. 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.
