10 /CUTTERS EDGE FIRE RESCUE SAWS
NOTE
Note that you must depress the safety lock on top
of the handle to be able to pull the trigger (Fig. 14).
The trigger cannot be pulled without depressing
this safety lock.

You may stop the saw with the momentary contact switch
or you may continue on to the chain run-in procedure.
RUNNING-IN THE CHAIN
The next step is running-in the chain. This important proce-
dure stretches and fully lubricates the chain.
Start the saw and run it at one-half to three-quarter speed
for approximately 10 minutes or until the bar and chain
begin to smoke.
Now turn off the saw. The chain has reached its operating
temperature. You will notice that the chain has sagged (Fig.
14).
Before readjusting, allow the chain to cool down for
three to five minutes, or until it is cool enough to touch with-
out discomfort.
Fig. 14. The chain will sag when hot.
Once it is cool enough to handle, readjust the chain to the
proper tension.
NOTE
Repeat this entire chain adjusting procedure once
more.
Running-in the chain will remove approximately 75% of
chain stretch. However, under normal use the chain will
continue to stretch throughout its life. Re-check the chain
tension during prolonged use and after each use.
BREAKING IN THE ENGINE
Proper breaking-in of the engine is a crucial step
in the set-up of your saw. This procedure allows
the cylinder to coat with oil and seat the piston
ring properly. If you skip this procedure and run
the saw at full throttle, severe damage to the
engine can occur.
NOTE:
Even though the chain will not turn at idle and no
bar and chain oil will be pumped, this break-in
procedure must be performed with the bar and
chain installed and with the bar and chain oil tank
filled.
Also be sure the chain brake remains disen-
gaged throughout the procedure.
To perform the initial engine break-in, start the saw and let
it idle through a complete tank of fuel. It is advisable to
briefly operate the saw at full throttle periodically during this
procedure to avoid "loading up". (Do not run the engine at
full throttle,
with "no load," for more than 2 seconds or
engine damage may occur!)
This is an initial engine break-in only. The engine will not be
completely broken-in until it has been operated through
several tanks of fuel.
