MAINTENANCE FUEL CAP CHAIN OIL CAP CHAIN BRAKE POST STARTER COVER Fig. 66 CLEAN CYLINDER FINS Fig. 67 CLEAN FLYWHEEL FINS Fig. 68 CHECKING THE FUEL FILTER See Figure 69. Check the fuel filter periodically. If contaminated or damaged, have fuel filter replaced by an authorized service center. REPLACING THE SPARK PLUG See Figure 70. This engine uses a Champion RCJ-6Y with .025 in. electrode gap. Use an exact replacement and replace every 50 hours or more frequently, if necessary. n Loosen the spark plug by turning it counterclockwise with a wrench. n Remove the spark plug. n Hand thread the new spark plug, turning it clockwise. Tighten securely with wrench. NOTE: Be careful not to cross-thread the spark plug. Cross-threading will seriously damage the cylinder. SPARK ARRESTOR The spark arrestor must be cleaned or replaced every 50 hours or yearly to ensure proper performance of your product. Spark arrestors may be in different locations depending on the model purchased. Please contact your nearest authorized service center to have your spark arrestor cleaned or replaced. INSPECTING AND CLEANING CHAIN BRAKE See Figure 71. n Always keep the chain brake mechanism clean and lightly brush the linkage. n Always test the chain brake performance after cleaning. Refer to Operating Chain Brake for additional information. WARNING: Even with daily cleaning of the mechanism, the dependability of a chain brake to perform under field conditions cannot be certified. Keep the SAFE-T-TIP® nose guard on the saw’s guide bar and use proper cutting techniques. MAINTENANCE FUEL FILTER Fig. 69 Fig. 70 CLEAN THE CHAIN BRAKE Fig. 71 STORING THE PRODUCT n Clean all foreign material from the product. Store it in a well-ventilated place that is inaccessible to children. Keep away from corrosive agents such as garden chemicals and de-icing salts. n Abide by all Federal and local regulations for the safe storage and handling of gasoline. When storing 1 month or longer: n Drain all fuel from tank into a container approved for gasoline. n Run the engine until it stops. This will remove all fuel-lubricant mix that could become stale and leave varnish and gum in the fuel system. n Squeeze primer bulb several times to purge fuel from carburetor. n Drain all bar and chain lubricant from tank into a container approved for oil. n Always place the scabbard over the guide bar and chain before transporting or storing the unit. MAINTENANCE HIGH ALTITUDE ENGINE OPERATION Please have an authorized service center adjust this engine if it is to be run above 2000 feet. Failure to do so may result in poor engine performance, spark plug fouling, hard starting, and increased emissions. Carburetor adjustment by an authorized service center will improve performance and allow that this engine meets EPA (Environmental Protection Agency) and California ARB (Air Resources Board) emission standards. An engine adjusted for high altitudes can not be run at 2000 feet or lower. In doing so, the engine will overheat and cause serious engine damage. Please have an authorized service center restore high altitude modified engines to the original factory specification before operating below 2000 feet.
