TO LUBRICATE SPROCKET TIP: WARNING Wear heavy duty work gloves when performing this application to reduce risk of personal injury. 1, Unplug the chain saw from the power source. NOTE: It is not necessary to remove the saw chain to lubricate the guide bar sprocket tip. Lubrication can be done on the job. 2. Clean the guide bar sprocket tip. 3. Using disposable Lube gun, insert tip of lube gun into the lubrication hole and inject grease until it appears at the outside edge of the sprocket tip (Figure 6-1A). 4. Make sure that the CHAIN BRAKED is deactivated. Rotate the saw chain by hand. Repeat the lubrication procedure until the entire sprocket tip has been greased. -Or OIL PASSAGES - Oil passages at bar pad should be cleaned to ensure proper lubrication of the bar and chain during operation. This can be done using a soft wire small enough to insert into the oil discharge hole. NOTE: The condition of the oil passages can be easily checked. If the passages are clear, the chain will automatically give off a spray of oil within seconds of starting the saw,Your saw is equipped with an automatic oiler system. TO CLEAN GUIDE BAR RAILS: 1. Remove sprocket cover, bar and chain. (see Section 3.3) 2. Using a screwdriver, putty knife, wire brush or other similar instrument, clear residue from the rails on the guide bar. This will keep the oil passages open to provide proper lubrication to the bar and chain (Figure 6-16). 3. Reinstall the bar, chain, sprocket cover and bar bolt knob. (See Section 3-3). 6-1A 6-1B GUIDE BAR MAINTENANCE Most guide bar problems can be prevented merely by keeping the chain saw well maintained. Incorrect filing and non-uniform cutter and depth gauge settings cause most guide bar problems, primarily resulting in uneven bar wear. As the bar wears unevenly, the rails widen, which may cause chain clatter and difficulty in making straight cuts. Insufficient guide bar lubrication and operating the saw with a chain that is TOO TIGHT will contribute to rapid bar wear (see Section 6.2). To help minimize bar wear, the following guide bar maintenance is recommended. BAR WEAR - Turn guide bar frequently at regular intervals (for example, after 5 hours of use), to ensure even wear on top and bottom of bar. BAR GROOVES - Bar grooves (or rails which support and carry the chain) should be cleaned if the saw has been heavily used or if the saw chain appears dirty. Rails should always be cleaned every time the saw chain is removed. 6-2. CHAIN MAINTENANCE INSTRUCTIONS WARNING Unless you have experience and specialized training for dealing with kickback (see Safety Precautions), always use a lowkickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not completely eliminate kickback. A low-kickback or "safety chain", should never be regarded as total protection against injury. A low-kickback saw chain should always be used in conjunction with other kickback protection devices such as the CHAIN BRAKEVHand Guard furnished with your unit. Always use a replacement saw chain designed as "low-kickback" or a saw chain which meets the low-kickback performance requirements of ANSI (American National Standards Institute). A standard saw chain (a chain which does not have the kickback reducing guard links) should only be used by an experienced professional chain saw operator. 16
