the guide bar horizontal.

4. Grasp the saw chain in the middle of the guide
bar and lift up. The gap between the guide bar
and the tie strap of the saw chain should be
approx. 2 - 4 mm.
5. After adjusting the chain tension, tighten the
sprocket cover.
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.

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 unintentional disconnection.
