The information in this note has been prepared to raise awareness of the potential injuries and
hazards associated with the use of a chainsaw for general cross-cutting activities. Chainsaw users are encouraged to pursue training in this area through an accredited training organisation.
General safety precautions
o Read the owners manual for your chainsaw model. It will tell you the safety features for
your chainsaw and the correct way of operating it.
o Check your chainsaw thoroughly before use.Make sure your chain and sprocket are in
good condition and that all safety devices are operating correctly. If you are not sure, take it
to a service agent.
o Always wear suitable protective clothing (see below).
o Keep other people and animals away from the work area. Do not become distracted. Stop
the chainsaw if somebody starts speaking to you.
o If tired, take a rest. Chainsaw operation requires constant attention and tired operators have more accidents.
Regularly:
o Sharpen your saw chain;
o Check the guide bar for burring; and
o Service your chainsaw.
Before you start cutting, check that:
o The machine is in good repair (no wear, damage or leaks);
o The chain brake is working
o The throttle trigger, safety throttle lock and stop switch work correctly;
o The chain is lubricated, sharp and tension is correct; and
o The carburettor idle is adjusted correctly.
After using your chainsaw:
o Clean the chainsaw (particularly the air filter, cooling inlets and sprocket cover).
Preventing hearing loss
o Most chainsaws emit noise levels that can cause permanent damage to your hearing if used for long periods at a time.
o Always use safety standards approved earmuffs or plugs.
o Ensure your muffler is in good condition.
o Ensure your engine is tuned to manufacturer specifications.
Preventing exhaust poisoning
o The exhaust gasses from your chainsaw contain poisonous elements such as carbon monoxide.
o Ensure your muffler is in good condition.
o Do not work in confined spaces.
Preventing fires
o Refuel in an area clear of flammable material.
o Refuel the chainsaw only after the engine has been turned off and allowed to cool down.
o Do not smoke while operating or filling the chainsaw.
o Move at least 10 feet away from the refuelling area before starting.
o Make sure caps are screwed on tightly and any fuel spillage is wiped off.
o Only use safety approved fuel containers.
o Keep a fire extinguisher or knapsack nearby when fire restrictions are in force or there is a
reasonable chance of a fire starting.
Personal safety equipment
Approved safety helmets with visor or goggles, earmuffs, protective leggings, steel capped safety
boots and gloves should be worn to protect you from chainsaw injury
Using your chainsaw
o Do not operate your chainsaw with the throttle lock engaged. Engine speed cannot be controlled with the throttle trigger in this position.
o Always hold your chainsaw firmly with both hands.
o Position your chainsaw so that your body is clear of the cutting bar.
o Make sure your chainsaw does not touch any foreign materials. Stones, nails etc. may be flung off, damage the saw chain or cause the saw to kick back unexpectedly.
o Take special care when cutting shatter wood - sharp slithers of wood may be caught and flung in your direction.
o If on a slope, stand on the uphill side or to one side of the log. Watch out for rolling logs.
Preventing kickback
Kickback occurs when the chainsaw bar is flung upwards uncontrollably during crosscutting,
usually striking the operator in the head at speed causing serious injury or death. This is caused by the chain on the top quarter of the nose bar, hitting a solid object or being pinched during
sawing. The force of the chain (travelling at up to 60kph at full throttle) flings the tip of the bar in an
arc at the operator quicker than the operator can react.
To prevent injury from kickback:
o Ensure your machine is fitted with a chain brake (preferably inertia activated);
o Ensure the brake mechanism is clean and operates effectively;
o Use low kick back type chain and avoid lowering the depth gauges too much when sharpening;
o Hold the chainsaw firmly, making sure the left hand encircles the top handle with the thumb
underneath;
o Avoid bringing the upper quadrant of the guide bar into contact with any foreign object;
o Do not cut above shoulder height; and
o Always begin your cut at peak revs.
Logs under tension
o Always start first cut on the compression side to a third of the diameter, then perform the second cut at the tension side - otherwise the saw will become jammed.
o For logs touching the ground cut three quarters of the way through the log then roll over to complete the cut - this will avoid damaging the chain.
