Lubrication
006921
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 pre-
006922
vent any dirt from entering the oil tank.
1
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
006935
2-4mm
WARNING:
• Always withdraw the mains plug before checking the chain tension, and
wear safety gloves.
5
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.
4
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 acci-
dent risk.
If the chain is too slack: Refer to the section titled " Adjusting saw chain tension
" and adjust the saw chain tension again.
