10. IMPORTANT OPERATING POINTS/STOPPING THE CUTTER/TRIMMER
Observe the applicable accident prevention regulations.
Starting
Move at least 3 m away from the place of refueling. Place the brush cutter on a clean piece of ground taking
care that the cutting tool does not come into contact with the ground or any other objects.
1. First place the machine on the ground.
2. Give a gentle push on the primer pump repeatedly (10 times) until fuel comes into the primer pump.
(Fig.12A)
3. Push the choke lever to the close position. (Fig.12B)
4. Slowly pull the starter grip until resistance is felt and continue with a smart pull. Do not pull out the starter
rope to its full extent and do not allow the starter handle to be retracted without control. Maintain control of the
starter rope and ensure it retracts slowly.(Fig.12C)
5. Repeat the starting operation until you hear the engine’s initial ignitions.
6. When starting cool engine, turn choke lever to “on” position. (Fig.12D)
7. Run the engine for approximately one minute at a moderate speed before applying full throttle.

Fig.12C Fig.12D
Note: If the starter handle is pulled repeatedly when the choke lever remains at “on” position, the engine
will not start easily due to excessive fuel intake.
In case of excessive fuel intake, remove the spark plug and pull the starter handle slowly to remove excess
fuel. Also, dry the electrode section of the spark plug.
CAUTION: Always reduce the engine revolutions when the equipment is not being used for work.
Operating the equipment at high revolutions when not being used for work will shorten the lifespan of the
equipment.
