NOTE: Every unit is run at the factory and the carburetor is set in compliance with emission regulations. Carburetor adjustments, other than idle speed, must be performed by an authorized Shindaiwa dealer. 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! If the idle speed cannot be adjusted by the procedure described here, return the trimmer to your Shindaiwa dealer for inspection. Idle Speed Adjustment 1. Place the unit on the ground, then start the engine, and then allow it to idle 2-3 minutes until warm. 2. If the attachment rotates when the engine is at idle, reduce the idle speed by turning the idle adjustment screw counter-clockwise. 3. If a tachometer is available, adjust idle. Check Specifications page for correct idle speed NOTE: Carburetor fuel mixture adjustments are preset at factory and cannot be serviced in the field. Idle adjustment screw Adjusting engine idle Loading Trimmer Line 1. Cut one piece of line to recommended length. 2. Align arrows on top of knob with openings in eyelets. 3. Insert one end of trimmer line into an eyelet, and push line equal distance through trimmer head. 4.

Stored fuel ages. Do not mix more fuel than you expect to use in thirty (30) days, ninety (90) days when a fuel stabilizer is added. Whenever the unit will not be used for 30 days or longer, use the following procedures to prepare it for storage: ¦ Clean external parts thoroughly. ¦ Drain all the fuel from the fuel tank. ¦ Remove the remaining fuel from the fuel lines and carburetor. 1. 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. CAUTION! Gasoline stored in the carburetor for extended periods can cause hard starting, and could also lead to increased service and maintenance costs. IMPORTANT! All stored fuels should be stabilized with a fuel stabilizer such as STA-BIL™. NOTE: Damage resulting from stale or contaminated fuel is not covered by the Shindaiwa warranty policy. ¦ Remove the spark plug and pour about 1/4 oz. of 2-cycle mixing oil into the cylinder through the spark plug hole. Slowly pull the recoil starter 2 or 3 times so oil will evenly coat the interior of the engine. Reinstall the spark plug. ¦ Before storing the unit, repair or replace any worn or damaged parts. ¦ Remove the air cleaner element from the carburetor and clean it thoroughly with soap and water. Let dry and reassemble the element. ¦ Store the unit in a clean, dust-free area.
