STOPPING THE ENGINE
Release the throttle lever and let the engine return to idle.
(B, Fig. 15). Turn off the engine, putting the ON/OFF
switch (A) in the STOP position. Do not put the chain saw
on the ground when the chain is still moving.
BREAKING-IN THE CHAIN
New chains will stretch and must be tightened frequently.
Tension adjustment must only be made when the chain
is cool.
1. Turn the chain and lubricate it with additional oil
(Fig. 16).
2. Start the saw and allow it to run at moderate speed.
Check to make sure that the oil pump is working
properly (Fig. 17).
3. Stop the engine and adjust the chain tension.
4. Start the saw again and make a few cuts in the trunk
of a tree to heat up the chain.
5. Stop the engine and allow the chain to cool and
adjust again.
6. Repeat this process until the chain retains proper
tension.
Do not touch the ground with the chain during this
process.
Never touch or adjust the chain while the engine is
running.
