The choke lever is mechanically connected to the carbure-
tor’s choke valve. The choke valve is closed when the choke
lever is on I and open when the choke lever is moved away
from I.
When starting a cold engine only keep the choke slide in the
I position until the engine begins to fire. Even if you do not
hear the engine firing, always open the choke after pulling
the starter rope three or four times. If you leave the choke
slide in the I position, the combustion chamber will flood
and stall the engine.
If you have moved the choke slide away from I after the
engine has fired or after three or four pulls on the starter
rope and the engine still refuses to start, you can assume
that the combustion chamber is already flooded. In such a
case, remove and dry off the spark plug. With the spark plug
still removed and the stop switch on G, clear the combus-
tion chamber by cranking the engine several times on the
starter. When you now try to start, move the choke lever
away from I and set the throttle trigger to the start position.
The stop switch should again be moved away from G.
In very cold weather only open the choke partially after the
engine begins to fire – move choke lever to about the center
position. Allow engine to warm up for a brief period with the
throttle in the start position. Then move choke lever com-
pletely away from I and disengage the starting throttle
lock.
A new engine or one which has been run until the fuel tank
is dry will not start first time after fueling because the fuel
pump only begins to deliver sufficient fuel of the carburetor
after the engine has been turned over a few times on the
starter.
8. Disengage the chain brake before starting cutting work
by pulling the hand guard back toward the handle-
bar .
9. The engine is shut down by sliding the stop switch
to G.
