CAUTION:
Prevent the oil from coming into contact with the
•
skin and eyes. Contact with the eyes causes
irritation. In the event of eye contact, flush the
affected eye immediately with clear water, then
consult a doctor at once.
Never use waste
•
carcinogenic substances. The contaminants in
waste oil cause accelerated wear of the oil pump,
the bar and the chain. Waste oil is harmful to the
environment.
When filling the chain saw with chain oil for the
•
first time, or refilling the tank after it has been
completely emptied, add oil up to the bottom edge
of the filler neck. The oil delivery may otherwise be
impaired.

1. Clean the area around the oil filler cap thoroughly
to prevent any dirt from entering the oil tank.
2. Unscrew the oil filler cap and add oil up to the
lower edge of the filler neck.
3. Screw the oil filler cap firmly back in place.
4. Wipe away any spilt chain oil carefully.

may take up to two minutes for the saw chain oil to
begin its lubricating
mechanism. Run the saw without load until it does
so (see "CHECKS ").

Make sure the saw chain fits snugly against the lower
side of the bar (see circle).
Check the chain tension frequently, as new chains are
subject to elongation.
Excessively high tension of saw chain may cause
breakage of saw chain, wear of the guide bar and
breakage of the adjusting dial.
A chain which is too loose can jump off the bar, and
therefore presents an accident risk.
If the chain is too loose: Refer to the section titled
"Adjusting saw chain tension" and adjust the saw chain
tension again.
Checking the switch action
CAUTION:
Before plugging in the tool, always check to see that the
switch trigger actuates properly and returns to the
"OFF" position when released.
To prevent the switch trigger from being accidentally
pulled, a lock-off button is provided.
To start the tool, depress the lock-off button and pull the
switch trigger. Release the switch trigger to stop.
Do not pull the switch trigger hard without depressing
the lock-off button. This may cause switch breakage.
Checking the chain brake
NOTE:
If the chain saw fails to start, check whether the
•
saw
chain brake is released. To release the chain
brake, pull the hand guard backwards firmly until
you feel it engage.
