POINTS IN OPERATION AND HOW TO STOP

Follow the applicable accident prevention regulations.

Starting

Move at least 3 m away from the place of refueling. Place the machine on a flat, bare surface so that the cutting blade does not contact the surface of ground or any other objects.

Cold start

For machine with U Handle or Loop Handle

-Move the switch (1) to the “I” position.

-Push gently the primer pump (A) 8 to 10 times.

-Set the choke lever (B) to the “CHOKE” position (C).

Note : Depress the trigger safety lock (E) before squeezing trigger.

-Squeeze the trigger (F) to full throttle position and hold it, and then set the switch (1) to the “START” position and release the trigger (F).

-Pull the starter until the engine tries to run (No more than 6 pulls ).

-Set the choke lever to half choke position.

-Pull the starter until the engine start running.

After the engine runs for 30 to 45 seconds at the “START” position ( for warming up the engine ), move the choke lever to the “RUN” position ( D ).

Warm Start ( Re-starting Engine )

- Set the choke lever (B) to the “RUN” position (D).

Note : You do not need to pull the trigger or set the throttle-lock when the engine is warm.

- Pull the starter rope until the engine runs.

STOPPING

Release the trigger (F) fully, and push the switch (1) to the “O” position that the engine will stop.

Be aware that the cutting blade may not stop immediately and allow it to slow down fully.

IDLE SPEED ADJUSTMENT

Your DOLMAR engine has been adjusted at the factory for optimum performance and fuel consumption, and no fur- ther adjustment is required.

Due to varying atmospheric and climatic conditions, however, you may need some minor adjustment for your area.

Checking the idle-speed

The idle-speed should be set to 2,800 – 3,300 rpm. If necessary, adjust the idle-speed using with a tachometer to insure the proper idle-speed. Note that the cutting blade or the nylon cutting head must not turn when the engine is on idle.

Adjusting the idle rpm. Can be done by turning the idle-speed screw (A) clockwise ( for increasing the engine speed ) or counterclockwise ( for decreasing the engine speed ).

If the engine does not idle properly after the adjustment, contact your nearest Dolmar dealer for service.

RE-SHARPENING THE CUTTING TOOL

CAUTION :

The cutting blades mentioned below should only be re-sharpened by an authorized facility. Manual re-sharpening will result in imbalances of the blade causing abnormal vibrations and damage to the machine.

- Cutter Blade : star blade ( 4 teeth ), eddy blade ( 8 teeth )

An expert service for re-sharpening and balancing is provided by Authorized Service Agents.

NOTE :

To increase the service life of the above cutter blade, it may be turned over once until both cutting edges have become blunt.
