OPERATION
Before Starting The Engine
Check for loose screws and nuts and fill with properly mixed fuel. Place the
engine on stable ground with the engine stand (fuel tank) and the guard
resting on the ground.
To Start A Cold Engine
1. Push the priming pump 5 times.
2. Fully close the choke lever.
3. Set the switch to the
I
position.
4. Hold the trimmer shaft near the engine firmly and pull the starter strongly.
5. When ignition is heard, reset the choke and pull the starter.
6. Warm up the engine for about 3 minutes.
7. When the engine has started at the initial ignition open the choke lever
gradually.
To Start A Warm Engine
1. Fully open the choke lever.
2. Push the priming pump 5 times.
3. Hold the handle and depress the throttle trigger. Release the throttle
trigger while pushing the throttle lock button on the handle.
4. Set the switch to the
I
position.
5. Hold the trimmer shaft near the engine firmly and pull the starter strongly.
6. If the engine does not start, repeat 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 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.
Stopping
Do not suddenly stop the engine when operating the machine at high speeds.
Gradually release 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.
Attaching the Harness
Attach the clip on the harness to the loop on the control handle and adjust to
suit the operator.
