Checking Your Chainsaw

Make these checks - which only take a minute or two - part of your routine whenever you get your chainsaw out.

• Check that your chainbrake is in working order or you have a rigid-type hand guard fitted or a mitt securely laced to the front handle.
• Check that the lubrication system is working - rev the engine and operate for a few seconds before switching off. Check the chain to ensure it is properly lubricated.
• Alternatively, activate the oiler while pointing the bar towards an object such as a stump and wait for the oil to show up.
• Check that the throttle control lockout, throttle control trigger and the on/off switch are operating correctly.
• Check that the chain is sharpened and tensioned to the manufacturer's instructions. When the cutters are sharp, with correct angle and depth gauge settings, the chain will do the work. When the chain is incorrectly sharpened and maintained, you work harder by having to force the chainsaw into the cut.
• Check that the chain stops moving when the throttle control trigger is released.
• Check that all external fittings are secure - check nuts, bolts, etc.
• Check that the high-tension lead does not show signs of wear, especially where it passes through the body of the chainsaw.

Pay particular attention to these checks if you've lent your chainsaw to anyone -they may not have taken the same care that you do!

Some Do's and Don'ts

• Never operate a chainsaw that is damaged, not properly adjusted to the manufacturer's recommendations, incorrectly assembled or with parts missing, especially safety devices.
• Except for fine-tuning the carburettor, never adjust chainsaw parts while the motor is running.
• Always turn your chainsaw off when handling the chain, guide bar or sprocket.
