Lubricate the saw chain and bar using biologically
degradable saw chain oil with an adhesion agent. The
adhesion agent in the saw chain oil prevents the oil from
being thrown off the saw excessively quickly. Mineral oils
must not be used, as they are harmful to the environment.
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 oil. Waste oil contains 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.

To fill the oil, perform the following steps:
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.
NOTE:
When the chain saw is used for the first time, it
may take up to two minutes for the saw chain oil to
begin its lubricating effect upon the saw
mechanism. Run the saw without load until it does
so (see "CHECKS ").
CHECKS
Before starting work, carry out the following checks:
Checking the chain tension
WARNING:
Always withdraw the mains plug before checking
the chain tension, and wear safety gloves.

The saw chain is correctly tensioned when it is in contact
with the underside of the bar and can be raised
approximately 2 - 4 mm from the bar by light finger pressure.
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.
