4. Tighten the saw chain until the lower side of the
saw chain fits in the guide bar rail (see circle).
5. Keep holding the guide bar lightly, tighten the
sprocket cover after adjusting the chain tension.
Make sure that the saw chain does not loose at
lower side.
Make sure the saw chain fits snugly against the lower
side of the bar.
CAUTION:
Do not tighten the saw chain too much.
•
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.
Carry out the procedure of installing or removing
•
saw chain in a clean place free from sawdust and
the like.
Engaging extension cord

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

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
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 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.
Fig.15
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.
