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)
50
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 35).
Engine is Flooded
If you did not move the choke lever to warm start, quickly enough
after the engine began to fire, the combustion chamber is flooded.
• Set the on/off swich to STOP.
• Open the twist lock (1, Fig. 50) in the direction of the arrow.
• Remove the filter cover (2).
• Engage a suitable tool in the spark plug boot (3, Fig. 51).
• Pry off the spark plug boot.
• Unscrew and dry off the spark plug.
• Open the throttle wide.
• Pull the starter rope several times to clear the combustion
51
chamber.
• Refit the spark plug and connect the spark plug boot, press it
down firmly – reassemble the other parts.
• Set the on/off swich to I, the starting position.
• Set the choke lever to warm start – even if engine is cold.
• Now start the engine.
Stopping The Engine
Release the throttle trigger (B, Fig. 52) and let the engine return
to idle.
Switch off the engine, returning the choke lever (C) to the fully up
position (3). Do not put the chain saw on the ground when the
chain is still moving. For additional safety, set the chain brake
when the saw is not in use.
In the event that the "STOP" position of the switch will not
function, pull the choke lever out to the fully extended position
/ Full Choke, refer to Fig. 52 to stop the engine.
52
CAUTION: The chain contracts as it cools down. If it
is not slackened, it could damage the crankshaft
and bearings.
Pre-operation checking
WARNING: THE SAW CHAIN SHOULD NEVER TURN
AT IDLE. Turn the idle speed screw "T" 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 saw
chain turning at idle.
