Carburetor adjustments, other than idle speed, must be performed by an authorized Shindaiwa dealer.. Maintenance (continued) Adjusting Engine Idle The engine must return to idle speed whenever the throttle lever is released. Idle speed is adjustable, and must be set low enough to permit the engine clutch to disengage the cutting attachment. WARNING! The cutting attachment must NEVER rotate at engine idle!

Check Specifications page for correct idle speed NOTE: Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field. Blade Sharpening WARNING! Wear protective gloves when handling or performing maintenance on the blade. When the cutting edges of the blade become dull, they can be resharpened with a few strokes of a file. In order to keep the blade in balance, all cutting edges must be sharpened equally. WARNING! Sharpen only the cutting teeth of a blade. DO NOT alter the contour of the blade in any way. Multiple-tooth Circular Blade Use a round file to maintain a radius of 0.04 to 1 to 1.5 mm (0.06”) at the base of each tooth. Cutting edges must be offset equally on each side.

Prime the primer bulb until no more fuel is passing through. 2. Start and run the engine until it stops running. 3. Repeat steps 1 and 2 until the engine will no longer start. ¦ Remove the spark plug and pour about 1/4 ounce of 2-cycle mixing oil into the cylinder through the spark plug hole.
