1. Oil tank should be filled every time that fuel tank is
filled.
2. Tension chain per instructions in “Maintenance –
Adjusting the Chain Tension” earlier in this manual.
3. Run at half throttle 30 to 45 seconds. Stop saw and
check for oil dripping from SAFE-T-TIP and guide
bar. If oil is present the chain may be dull or bar
may be damaged. If no oil is on the SAFE-T-TIP,
contact a Homelite service dealer.
1. Release chain brake, refer to “Operation – Operating
Chain Brake” earlier in this manual.
2. Tension chain per instructions in “Maintenance –
Adjusting the Chain Tension” earlier in this manual.
3. Refer to “Maintenance – Assembling the Bar and
Chain” earlier in this manual.
4. Inspect guide bar and chain for damage.
NOTE: The carburettor adjustment needles are equipped with
plastic caps which prevent anticlockwise rotation from the
original factory adjustment. If your product exhibits specific
performance problems where the Troubleshooting Section
recommends an anticlockwise needle adjustment and you have
made no adjustments since the original purchase, take the
product to a factory-authorised service dealer for repair. In most
cases, the needed adjustment is a simple task for the factory-
trained service representative.
