WARNING!

IT IS VERY IMPORTANT THAT YOU READ THIS
MANUAL BEFORE OPERATING YOUR CHAINSAW

CHAINSAWS CAN BE DANGEROUS

Each year many people are injured in chainsaw
accidents. Most of these accidents can be avoided. The
hands, knees, feet and head are most vulnerable to
being cut by the saw chain.

If you use a chainsaw often, there are also other health
risks. The continual noise of the chainsaw can lead to
permanent hearing loss and vibration can cause
permanent damage to the hands.

These hazards mean that chainsaws are potentially one
of the most dangerous pieces of industrial equipment if
not used correctly.

With the use of the correct protective clothing, and
proper work practices, this equipment can be used
safely.

In the next few pages you’ll read valuable information
concerning safe chainsaw operation. There is a checklist
of the safety instructions. Tips on the protective clothing
you should wear, and suggestions for safe work methods
are provided. Please read on!

GENERAL SAFETY PRECAUTIONS

 This owner’s manual will tell you the safety features of your

chainsaw and the correct way of operating it.

 Check your chainsaw thoroughly before use. Make sure your

bar, chain and sprocket are in top condition and that all safety
devices are working properly.

 Regularly service your chainsaw.
 Always wear protective clothing. Gloves, safety helmet with

visor or goggles, earmuffs, protective leggings and safety
boots should be worn at all times whilst operating your
chainsaw.

 Do not start cutting until you have a clear work area, secure

footing and a planned retreat path from the operating area.

 Keep other people and animals well away from the working

area.

 Make sure there is a second person within calling distance.
 Do not operate a chainsaw that is beyond your ability.
 Use the chainsaw only to cut the correct material with the

correct chain.

 Do not become distracted. Stop the chainsaw if somebody

starts speaking to you.

 If you are tired, rest! Chainsaw operation requires maximum

and constant concentration. Tired operators can have
accidents.

PERSONAL SAFETY EQUIPMENT

Gloves, safety helmet with visor or goggles, earmuffs, protective
leggings and safety boots should be worn at all times whilst
operating your chainsaw to protect you from chain saw injury.

PREVENTING KICKBACK

Kickback is a sudden upward and backward movement of the
saw. It occurs when the tip of the bar nose contacts a log,
branch or nail. It can cause serious injury.

FIGURE 1

TO PREVENT INJURY FROM KICKBACK

 Ensure your chain saw is fitted with a chain protector safety bar

and a bumper spike.

 Use low kickback chain types and avoid lowering the depth

gauges too much when sharpening.

 Hold the chainsaw firmly making sure that the left hand

encircles the top handle with the thumb underneath.

 Avoid bringing the upper quadrant of the guide bar into

contact with any foreign object.

 Wear correct head protection and safety pants at all times.
 Avoid cutting above your shoulder height.
 Never hold the chainsaw in one hand.
 Always begin at peak (rev’s) power.

PREVENTING RAYNAUD’S DISEASE AND OCCUPATIONAL OVERUSE

SYNDROME

The vibration from chainsaws can cause damage to the hands if
used for long periods of time.

 Use the chainsaw with ergonomically angled handles. These

greatly reduce uneven and undue pressure on the hands.

 Take regular rest breaks from continuous operations.
 Wear gloves.
 Sharpen your chain regularly. This will ensure smoother cutting

and less vibration.

MAINTAINING YOUR CHAINSAW

A chainsaw is designed to meet various safety requirements. Use
the diagrams to check and understand the safety features, even
if they may be optional extras when you buy it.

Never operate a chainsaw that is damaged, not properly
adjusted or wrongly assembled. Your chainsaw requires regular
maintenance.

IMPORTANT!
If your chainsaw is used underwater, the motor must be flushed
immediately after use with preservatives such as Valvoline Tectyl

930.

BEFORE YOU START WORK, CHECK THAT…

1. The machine is in good condition (no leaks, wear or damage).

2. The throttle trigger and safety throttle lock operate correctly.

3. The chain is lubricated, sharp and tension is correct.

4. The air pressure is correct. Maximum 7 bar – do not exceed!

AFTER FINISHING YOUR WORK, OR DAILY…

1. Clean the chainsaw, particularly the sprocket guard.

2. Check the chainsaw thoroughly from top to bottom, see that it

is lubricating properly.

REGULARLY…

1. Sharpen your saw chain.

2. Check the guide bar for burring.

3. Check the sprocket for wear. It can clog up with oil and dirt

and may malfunction.

4. Have your chainsaw serviced regularly.

PREVENTING NOISE INDUCED HEARING LOSS

Most chainsaws emit noise levels that can cause permanent
damage to your hearing if used for long periods at a time.

 Always use safety standards approved earmuffs or plugs.
 Ensure your chainsaw is tuned to manufacturers specifications.

PREVENTING FIRES

1. Don’t smoke while operating the chainsaw.

2. Keep a fire extinguisher, spray pump and shovel nearby.

TRAINING AND SUPERVISION

Chainsaw operators should be properly trained. Training may be
on-the-job or through a recognised training course. Training
should include instructions on:

 Safe working techniques.
 Operating conditions, including unusual or dangerous

conditions.

 Basic information about the chainsaw and its controls,

attachments and components, design capacity, stability and
limitations.

 Correct stopping and starting techniques.
 Cleaning and servicing.
 Being alert for the possibility of kickback.
 Chain sharpening techniques.

Less experienced operators should be carefully supervised.

Certain operations are extremely dangerous and should only be
undertaken by professionals. These include the removal of
branches from standing trees, the removal of trees hung up in
wires, cutting trees thicker than the guide bar length, and working
in windblown and foul weather areas.

A REVIEW OF SAFETY PROCEDURES

 Operator should wear dress of close fitting style, safety boots

and leather gloves.

 When carrying the chainsaw about, the chain should be fitted

with a chain guard.

 Chainsaws should never be run without oil.
 Always hold the saw with both hands and keep a firm stance

when working with the chainsaw.

 No other person should stand within the working radius of the

saw.

 Before you start cutting, press the spike bar against the

material being cut.

 When cutting splintered wood, take precaution. Large splinters

can fly towards the operator.

 Only use the underside of the bar when cutting at shoulder

height. T

 he pressure hose should be closed when the chainsaw is set

aside even for a short while or when the chain tension is tested
or adjusted.

 The operator should always work calmly and cautiously and

should also avoid any danger to themselves or other persons.

ASSEMBLING THE GUIDE BAR AND CHAIN

Direction of the chain travel (L), the cutting edges of the chipper
chain on the top edge of the guide bar must face in the direction
of the guide bar nose. Put the pivot of the square nut for chain
tensioning into the tap-hole in the guide bar. Assemble the
sprocket guard and screw the nut finger tight.

TIGHTENING THE CHAIN

Turn the tensioning screw clockwise. The nose of the guide bar
should be lifted slightly. The chain should not sag but should be
easily moved by hand (wear gloves) alongside the guide bar.
Tighten sprocket guard nut. A newly fitted chain should be
allowed to rotate for 5 minutes with good lubrication and then
re-tighten the chain.
