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

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 (4 - 8") from
the extension cord connector. This helps prevent
unintentional disconnection.

Reclaimend
oil
006921
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.
