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.
