Resumen del manual
See Figure 68. The bar should be cleaned every day of use and checked for wear and damage. Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur. A bar with any of the following faults should be replaced: Q Wear inside the bar rails that permits the chain to lie over sideways Q Bent guide bar Q Cracked or broken rails Q Spread rails In addition, lubricate guide bars with a sprocket at their tip weekly. Using a grease syringe, lubricate weekly in the lubricating hole. See Figure 68. Turn the guide bar and check that the lubrication holes and chain groove are free from impurities. MAINTAINING THE SAFE-T-TIP® NOSE GUARD CAUTION: Make sure the chain has stopped before you do any work on the saw. WARNING: Although the guide bar comes with a SAFE-T-TIP® anti- kick-back device already installed, be sure to check the tightness of the mounting screw before each use. Tighten the mounting screw of the nose guard as instructed below.These are specially hardened screws. If you cannot install the screw tightly, replace both the screw and the SAFE-T-TIP® before further operation. Do not replace the screw with an ordinary screw. In addition to preventing chain contact with solid objects at the nose of the bar, the SAFE-T-TIP® also helps keep the chain away from abrasive surfaces, such as the ground. Keep it on the right-hand side of the bar where it will be between the chain and the ground during flush with ground cutting. The mounting screw requires a 5/16 in. spanner or adjustable spanner to achieve the recommended tightness of 4-5 Nm (35 to 45 in. lb.). A tightness within this range can be achieved by using the following method. See Figure 69. 1. Tighten the screw with your finger. 2. Tighten the screw an additional three-quarters of a turn using a spanner. Fig. 68 LUBRICATING HOLE MOUNTING SCREW SAFE-T-TIP® Fig. 69 UK - Page 33 UK - Page 34 STOP STOP MOUNTING THE SAFE-T-TIP® NOSE GUARD See Figure 70. 1. Mount the SAFE-T-TIP® on the bar nose. See Figure 70. 2. Fit the locking rivet or tab in the recessed hole in the guide bar. 3. Tighten the screw with your finger. 4. From the finger tight position, tighten the screw an additional three-quarters of a turn using a spanner. CLEANING THE AIR FILTER NOTE: Always clean the air filter before making any mixture adjustments of the carburettor. 1. For access to the air filter and carburettor 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 carburettor, blow or brush as much loose dirt and sawdust from around the carburettor and chamber as possible. NOTE: Make sure to pull the choke rod out to keep the carburettor from being contaminated. 6. Remove the screw securing the air filter. 7. Position a flat screw driver between the tabs and twist as shown in the illustration. 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 alternative 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. TIGHTEN 3/4 OF A TURN Fig. 70 CAUTION: Never run the engine without the air filter; serious damage could result. Make sure the air filter is correctly placed in the air filter cover before reassembly. SCREW AIR FILTER RETAINING SCREW AIR FILTER CYLINDER COVER PRE-FILTER STARTER ASSEMBLY FAN HOUSING BAFFLE Fig. 71 Fig. 72 Fig. 73 .. Clean the pre-filter every 25 tanks of fuel or sooner, if required. Remove the cylinder cover, starter assembly and the fan housing baffle for access to the pre-filter in the engine housing. NOTE: If you use an air hose for drying, blow through both sides of filter. SCREWS MAINTENANCE UK - Page 35 STOP CLEANING THE ENGINE 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 drive case 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 dealer personnel. CLEANING THE STARTER UNIT Use a brush or compressed air to keep the cooling vents of the starter assembly free and clean of debris. CHECKING THE FUEL FILTER Check the fuel filter periodically. Replace it if contaminated or Fig. 74 damaged. CLEAN CYLINDER FINS CLEAN FLYWHEEL FINS Fig. 75 Fig....
