6. If the engine does not start repeat 9-2, the procedure for starting a cool 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 carburetor 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.
8-4. Before operation
After starting the engine, warm it up for about 3 minutes and increase the speed gradually.
8-5. Stop the engine
Do not suddenly stop the engine when operating at high speeds.
Gradually return the throttle trigger and idle the engine before setting the switch to STOP.
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.
8-6. When the engine does not start
If the engine does not start or flames flow back through the muffler even though you have pulled the starter many times, remove and check the
spark plugs.
1.
If the spark plugs are dry, no fuel has been fed into the cylinder. Check the fuel pipe and carburetor.
2.
Clean or replace the spark plugs if they are wet or dirty.
3.
If fuel has overflowed into the crank case, remove the spark plugs, open throttle and pull the starter 2 or 3 times
to remove excess fuel from the crank case.
