Operation
STARTING & STOPPING THE SAW
Failure to break-in an engine may result in piston seizure.
It is very important to break-in a new engine to “seat” all moving parts, especially
the piston rings. To break-in the engine, run one full tank of 4% (25:1) fuel at idle,
cycling the throttle every 5 to 10 minutes to prevent loading.
Do not obstruct air intake
.
Loose clothing can inadvertently be drawn into air intake and obstruct air flow
which may result in engine stall.
Be sure that no part of the cutting system is contacting a solid object when
starting the saw.
When the multifunction lever is set to the choke and/or throttle advance position
for starting, the chain may move and cause the saw to react if the chain contacts a
solid object.
Move the saw at least 3 m (10 ft) from the fueling area before starting it.
Assure that secure footing is established and chain is not contacting any
objects.
When starting the saw, place the saw on clear and level ground.
IMPORTANT
WARNING
CAUTION
STOPPING THE SAW
To turn the engine off, push the multi-function lever down until engine stops. The
multi-function lever will then remain in the “STOP” position and prevent starting.
Close water valve completely.
