○ If the oil is not ejected after rotating the chain for two
or three minutes, check to make sure that sawdust
has not collected around the oil outlet.
○ The amount of chain oil ejected can be adjusted with
the oil adjustment screw. (Fig. 13)
Cutting thick pieces of wood places a heavy load on
the saw chain, so make sure the amount of oil ejected
is increased at these times.

CAUTION
A soft-start function is activated when the chain
saw is switched on and the saw chain rotations
start off slowly.
Wait until the rotations have built up before
starting work.

PROTECTION CIRCUIT

The chain saw is equipped with a protection circuit
to prevent it from being damaged. The motor will
automatically stop if excessive load is placed on the chain
saw, such as when forcing it to cut through hard wood, etc.

In this event, switch the chain saw off , isolate the reason
for the motor stopping, and then switch it on again and
resume work once the cause of the problem has been
completely eradicated.
Wait for at least two seconds after switching the chain saw
off following an automatic halt before switching it on again.

CUTTING PROCEDURES

CAUTION
● Please note the position of the cord so that it will
not be caught on branches and the like, during
cutting.
● The fi rst-time user should, as a minimum
practice, cut logs on a saw-horse or cradle fi rst.
General cutting procedures:
1. Switch ON the power while keeping the saw slightly
away from the wood to be cut.
Start sawing only after the unit has reached full speed.
2. When sawing a slender piece of wood, press the base
section of the guide bar against the wood and saw
downward as shown in Fig. 14.
