CAUTION:
•
Always be sure that the tool is switched off and
unplugged before lubricating the saw chain.
Lubricate the saw chain and bar using a 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.
Clean the area around the oil filler cap shown in the figure
thoroughly to prevent any dirt from entering the oil tank.

Unscrew the oil filler cap and add oil up to the lower
edge of the filler neck.
Screw the oil filler cap firmly back in place.
Wipe away any spilt chain oil carefully.
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. A chain which is too slack can
jump off the bar, and therefore presents an accident risk.
If the chain is too slack: Refer to the section titled "
Adjusting saw chain tension " and adjust the saw chain
tension again.
Checking the switch action
CAUTION:
Always unplug the tool before testing the switch trigger.
Locking the switch trigger in the ON position is
prohibited.
