Resumen del manual


1. For access to the air filter and carburetor area, loosen the three screws holding the cylinder cover. 2. Activate chain brake. 3. Lift the front of the cylinder cover past chain brake lever. 4. Lift the back of the cylinder cover past the handle. 5. Before removing the air filter from the carburetor, blow or brush as much loose dirt and sawdust from around the carburetor and chamber as possible. Note: Make sure to pull the choke lever out to keep the carburetor from being contaminated. 6. Remove the screw securing the air filter. 7. Position a flat screw driver between the tabs and twist. 8. Lift the air filter off the air filter base. Choose one of the following cleaning options: 9. To lightly clean, tap the filter against a smooth, flat surface to dislodge most saw dust and dirt particles. 10. For a more thorough cleaning, clean in warm soapy water, rinse, and let dry completely. Note: An alternate method is to clean the filter with compressed air (always wear eye protection to avoid eye injury). 11. Reinstall the air filter, making sure that the tabs on the air filter are located in channels on the air filter bottom before tightening filter retainer screw. Page 31 CLEANING THE ENGINE See Figures 74 and 75. Clean the cylinder fins and flywheel fins with compressed air or a brush periodically. Dangerous overheating of the engine may occur due to impurities on the cylinder. WARNING Never run the saw without all the parts, including the drivecase cover and starter housing, securely in place. Because parts can fracture and pose a danger of thrown objects, leave repairs of the flywheel and clutch to trained Homelite Service Center personnel. CLEANING THE STARTER UNIT See Figure 73. Use a brush or compressed air to keep the cooling vents of the starter assembly free and clean of debris. CHECKING THE FUEL FILTER See Figure 76. Check the fuel filter periodically. Replace it if contaminated or damaged. REPLACING THE SPARK PLUG See Figure 77. This engine uses a Champion RCJ-4 with .025 in. (0.63 mm) electrode gap. Use an exact replacement and replace every six months or more frequently, if necessary. 1. Loosen the spark plug by turning it counterclockwise with a wrench. 2. Remove the spark plug. 3. Hand thread the new spark plug, turning it clockwise. Note: Be careful not to cross-thread the spark plug. Cross-threading will seriously damage the product. Note: Depending on the type of fuel used, the type and amount of oil used, and/or your operating conditions, the exhaust port and muffler may become blocked with carbon deposits. If you notice a power loss with your gas powered tool, you may need to remove these deposits to restore performance. We highly recommended that only qualified service technicians perform this service. MAINTENANCE STOP STOP Fig. 73 CLEAN CYLINDER FINS CLEAN FLYWHEEL FINS Fig. 74 Fig. 75 FUEL FILTER Fig. 76 Fig. 77 Page 32 CLEANING THE SPARK ARRESTING MUFFLER See Figure 78. The muffler is equipped with a spark arrestor screen. A faulty spark arrestor screen can create a fire hazard. Through normal use the screen can become dirty and should be inspected weekly and cleaned as required. Always keep the muffler and spark arrestor on your saw in good condition. WARNING Muffler surfaces are very hot during and after operation of the chain saw, keep all body parts away from the muffler. Serious burns may occur if contact is made with the muffler. 1. Allow the muffler to cool. 2. The spark arrestor screen is retained by the deflector. Remove the nuts and screen retainer to access the spark arrestor screen. 3. Replace the spark arrestor screen if it is cracked or otherwise deteriorated. CHAIN BRAKE See Figures 79 and 80. ¦ Remove the clutch cover and clean the chain brake components. Check wear on the brake band and replace if worn or deformed. The band thickness should not be less than 0.024 in. (.60 mm), or worn halfway through. ¦ Always keep the chain brake mechanism clean and lightly lubricate the linkage. ¦ Always test the chain brake performance after servicing or cleaning. Refer to “Operation - Operating Chain Brake” earlier in this manual for additional information. ¦ Check and, if damaged, replace the chain catcher. STORING THE CHAIN SAW (1 MONTH OR LONGER) 1. Drain all fuel from tank into a container approved for gasoline. 2. Run the engine until it stops. This will remove all fuel-oil mix that could become stale and leave varnish and gum in the fuel system. 3. Drain all bar and chain oil from tank into a container approved for oil. 4. Clean all foreign material from the saw. 5. Store it in a well-ventilated place that is inaccessible to children. Note: Keep away from corrosive agents such as garden chemicals and deicing salts. Abide by all federal and local regulations for the safe storage and handling of gasoline. Excess fuel can be used in other 2-cycle engine powered equipment requiring 50:1 ratio.
