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

A

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

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.
