6. If the engine does not start, repeat 9-2, the procedure for starting a cold engine.
CAUTION
1. After starting the engine, accelerate and decelerate the engine several times by opening and
closing the throttle trigger.
2. Air in the carburettor causes poor acceleration or engine stoppage.
3. Re-fuel before the fuel is used up. Starting the engine after using all of the fuel is very difficult.
9-4 Operation
After starting the engine, warm it up for about 3 minutes and gradually increase the speed.
9-5 Stopping
Do not suddenly stop the engine when
operating the machine at high speeds.
See Fig. 18 for the
Double-Handles
or Fig. 18-1
for the
D-Loop Handle
.
Gradually release the throttle trigger and idle
the engine before setting the switch to STOP.
Fig. 18 Fig.18-1
CAUTION
Do not operate the engine at high speeds with no load on the cutting attachment, especially when
the engine is new. When operated at high speeds with no load, it will accelerate to an excessively
high speed that might harm the engine.
