OPERATION

Breaking-in the Engine

The engine reaches the maximum power after 5-8 hours of activity.
During this period of breaking-in do not make the machine
function idly at full throttle, to avoid excessive functioning
stress.
CAUTION! – During the braking-in period do not vary
the carburetion to obtain a presumed power
increment; the engine can be damaged.

Difficult Starting (or starting a flooded engine)
The engine may be flooded with too much fuel if it has not started
after 10 pulls. Flooded engines can be cleared of excess fuel by
following the warm engine starting procedure listed above.
Ensure the ON/STOP switch is in the ON position. Starting could
require pulling the starter rope handle many times depending on
how badly the unit is flooded. If engine fails to start refer to the
TROUBLESHOOTING TABLE (page 30).
Engine is Flooded
If you did not move the choke lever to warm start, quickly enough

Stopping The Engine

Release the throttle trigger (B, Fig. 52) and let the engine return
to idle.
To stop the engine, move the on/off switch (A) to the "STOP"
position. Do not put the pole pruner on the ground when the saw
chain is still moving.
In the event that the "STOP" position of the switch will not
function, pull the choke lever in the CLOSE position
(Fig.48, page 19) to stop the engine.
CAUTION: The chain contracts as it cools down. If it
is not slackened, it could damage the sprocket shaft
and bearings.
Pre-operation checking
WARNING: THE SAW CHAIN SHOULD NEVER TURN
AT IDLE.
counterclockwise to reduce the idle RPM and stop
the chain, or contact a Servicing Dealer for
adjustment and discontinue use until the repair is
made. Serious personal injury may result from the
pole pruner chain turning at idle.
