Engaging extension cord
CAUTION:
• Make sure that the extension cord is unplugged
to the mains outlet.

cord 4. Plug and socket (the shape may
differ from country to country)
When engaging the extension cord, secure it to the
chain saw's cord with the cord hook.
Attach the cord hook about 100 - 200 mm from the
extension cord connector. This helps prevent uninten-
tional disconnection.

OPERATION

CAUTION:
• Hold the tool firmly with right hand on the rear
handle and left hand on the front handle when
performing the tool.
Switch action
► Fig.13: 1. Lock-off button 2. Switch trigger
CAUTION:
• Always be sure that the tool is switched off and
unplugged before checking function on the
switch trigger.
• 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.
Lubrication
CAUTION:
• Always be sure that the tool is switched off and
unplugged before lubricating the saw chain.
► Fig.14
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 carcino-
genic 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.
► Fig.15: 1. Oil filler cap 2. Strap
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 check-
ing the chain tension, and wear safety gloves.

4. Guide bar 5. Saw chain
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.
