To
optimize the life and reliability of your chain saw, it's
important to service it regularly. Here are a few points that
will help you bring order to your product service.
- Check the
throttle trigger for smooth operation. If any binding
occurs, or if engine fails to return to idle, the saw should
be taken to your dealer before it is used again. Also, be
sure that the trigger cannot be pulled until the throttle
trigger lockout is depressed.
- Clean the
chain brake and check its function according to the
instructions. Make sure that the chain catcher is undamaged.
Otherwise replace it immediately.
- Clean or
replace the air filter as necessary. Check for damage or
holes.
- The bar
should be turned daily for more even wear. Check the
lubrication hole in the bar, to be sure it is not clogged.
Clean the bar groove, if the bar has a sprocket tip, this
should be lubricated.
- Check the
function of the oiler to be sure the bar and chain receive
proper lubrication.
- Sharpen
the chain and check its tension and condition. Check the
drive sprocket for wear. Replace if necessary.
- Check the
starter and starter cord for wear or damage. Clean the air
intake slots on the starter housing.
- Check for
any loose nuts and screws and retighten if necessary.
- Test the
stop switch to be sure it shuts off the engine.
- Check the
cooling system of a saw fitted with a catalytic converter.
- Check
that the AV elements are not soft or torn.
- Lubricate
the clutch drum bearing.
- File off
burrs, if any, on the sides of the bar.
- Clean the
spark plug and check the gap. The correct gap is 0.5 mm
(0.020).
- Check the
starter and the recoil spring. Clean the fins on the
flywheel.
- Clean the
cooling fins on the cylinder.
- Clean or
change the screen in the muffler.
- Clean the
carburetor body and air box.

brake band on the chain brake for wear.
