Ensure that the WARNING: power cord is disconnected before performing any maintenance on your saw. Sprocket Tip Lubrication The sprocket tip on CAUTION: your new saw has been pre-lubricated at the factory. Failure to lubricate the guide bar sprocket tip as explained below will result in poor performance and seizure, voiding the manufacturer’s warranty. Lubrication of the sprocket tip is recommended after each saw use. Always thoroughly clean guide bar sprocket tip before lubrication. The Lube Gun (optional) is recommended for applying grease to the guide bar sprocket tip. The Lube Gun is equipped with a needle nose tip which is necessary for the efficient application of grease to the sprocket tip. Fig. 28 To lubricate the sprocket tip: 1.Unplug the chain saw from the power source. NOTE: It is not necessary to remove the saw chain tolubricate the guide bar sprocket tip. Lubricationcan be done on the job. Always use WARNING: protective gloves when handling the saw chain. 2. Clean the guide bar sprocket tip. 3. Using the Lube Gun (optional), insert tip of lube gun into the lubrication hole and inject grease until it appears at outside edge of sprocket tip (Fig. 28). 4. Make sure that the Chain Brake® is deactivated. Rotate saw chain by hand. Repeat lubrication procedure until the entire sprocket tip has been greased. Maintenance Procedures 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 chain that is too tight will contribute to rapid bar wear. To help minimize bar wear, the following guide bar maintenance procedures are 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 saw has been used heavily or if saw chain appears dirty. Rails should always be cleaned every time saw chain is removed. OIL PASSAGES - Oil passages on the bar 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. Cleaning Bar Rails 1. Remove sprocket cover, bar and chain. Refer to the Install the Guide Bar/Saw Chain section. 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 (Fig. 29). 3. Reinstall the bar, chain, sprocket cover and bar bolt knob. See Section Install the Guide Bar / Saw Chain for more information. Fig. 29 MAINTENANCE AND REPAIR INSTRUCTIONS MAINTENANCE AND REPAIR INSTRUCTIONS CHAIN MAINTENANCE Unless you have WARNING: experience and specialized training for dealing with kickback (see Safety Precautions), always use a low-kickback 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 Brake®/Hand Guard furnished with your unit. Always use a replacement saw chain designed as “lowkickback” 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. What is a Low-Kickback Saw Chain? A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1. By keeping the Chain Brake® and saw chain in good working condition and correctly serviced as recommended in this manual, you will be able to maintain the safety system of your chain saw over the life of the product. Chain Tension Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand. Breaking in a New Saw Chain A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly. Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. T...
