Replacing the spark plug Caution: Do not touch the spark plug or plug cap if the engine is running (high voltage). Switch off the engine before starting any maintenance work. A hot engine can cause burns. Wear protective gloves! The spark plug (Order No. 965 603 021) must be replaced in case of damage to the insulator, electrode erosion (burn) or if the electrodes are very dirty or oily. Remove the filter cover and hood. See Cleaning / changing the air filter. Pull the plug cap (7) off the spark plug. Use only the combination wrench supplied with the saw to remove the spark plug. CAUTION: To prevent damage to the decompression valve (8), when unscrewing the spark plug position the combination tool in such a way that it does not impact the valve. Electrode gap The electrode gap must be .020" (0.5 mm). 7 8 CAUTION: Use only BOSCH WSR 6F spark plug, CHAMPION RCJ-6Y or NGK BPMR 7A. 0,5 mm Checking the ignition spark Insert the combination tool (9) between the ventilation hood and cylinder only as shown in the illustration. CAUTION! Do not insert the combination tool into the spark plug hole, but make contact only with the cylinder (otherwise you may damage the engine). Using insulated pliers, hold the spark plug (10) (unscrewed but with the plug cap on) against the combination tool (away from the spark plug hole!). Switch the combination switch (11) to "I". Pull the starter cable hard. If the function is correct, an ignition spark must be visible near the electrodes. Replacing the suction head The felt filter (13) of the suction head can become clogged. It is recommended to replace the suction head once every three months in order to ensure unimpeded fuel flow to the carburetor. Unscrew the tank cap (12), pull the retainer out of the opening. Empty fuel tank. Use a wire hook to pull the suction out of the tank opening for replacement. Caution: Do not allow fuel to come into contact with skin! 24 12 13
