OPERATION
• Push the choke lever, (C, Fig. 47) fully down (1).
• Pull the starter rope a few times until the first kick over of the
engine is heard (no more than five (5) pulls). A new unit may
require additional pulls.
• Move the choke lever, (C, Fig. 48) to the intermediate position (2).
• Pull the starter rope to start the engine.
• Once the engine is going release the chain brake and wait for
a few seconds. Place chain brake lever / hand guard into the
run position as shown in Fig. 46. Refer to Safety-Chain Brake
and Operation-Chain Brake Sections for additional information.

• Then accelerate with the throttle (B, Fig. 49) to fire the half
throttle-blocking device.
WARNING: Do not cut material with the choke/fast
idle lever at the FULL CHOKE position. Do not ope-
rate your chainsaw with the starting throttle lock
engaged. Cutting with the starting throttle lock enga-
ged does not permit the operator proper control of
the saw or chain speed.
NOTE - STARTING WARM ENGINE:

Follow above starting instructions, but do not use the Full
Choke position for start up again. To set fast idle for warm
engine starting, pull choke out completely and push back in
to the original Run Position.
WARNING: Weather conditions and altitude may
affect carburetion. Do not allow bystanders close to
the chain saw while adjusting the carburetor.
WARNING: Never attempt to start the chainsaw when
the guide bar is in a cut or kerf.

WARNING: Never start the saw engine without the
bar, chain and clutch cover (chain brake) assembled
- or else the clutch can come loose and cause
personal injuries.

49A
In the event of temperatures below 0°C, move the cursor (A, Fig.
49A) to the winter position. The winter symbol (Fig. 49 A) must be
indicated by the arrow stamped on the slide. In this way heated air
from the cylinder is also taken in, preventing thus the formation of ice
inside the carburettor.
When the temperature rises above +10°C, move the cursor (A,
Fig. 49 B) to the summer position. Failure to reset this parame-
ter could impair motor performance due to overheating.
