Remember that the risk of forest fires is greater in hot or dry weather. Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-tocut wood becomes hard to cut and burn marks appear on the wood. Keep the chain at proper tension. Tighten all nuts, bolts and screws except the carburetor adjustment screws after each use. ! Warning! In order for the chain brake on your STIHL chainsaw to properly perform its function of reducing the risk of kickback and other injuries, it must be properly maintained. Like an automobile brake, a chainsaw chain brake incurs wear each time it is engaged. The amount of wear will vary depending upon usage, conditions under which the saw is used and other factors. Excessive wear will reduce the effectiveness of the chain brake and can render it inoperable. For the proper and effective operation of the chain brake the brake band and clutch drum must be kept free of dirt, grease and other foreign matter which may reduce friction of the band on the drum. For these reasons, each STIHL chainsaw should be returned to trained personnel such as your STIHL servicing dealer for periodic inspection and servicing of the brake system according to the following schedule: Heavy usage - every three months, Moderate usage - twice a year, Occasional usage - annually. The chainsaw should also be returned immediately for maintenance whenever the brake system cannot be thoroughly cleaned or there is a change in its operating characteristics. For any maintenance please refer to the maintenance chart and to the warranty statement near the end of this manual. Additionally, the daily maintenance schedule for your chainsaw set forth in your STIHL Owner's Manual should be strictly followed. Store chainsaw in a dry place and away from children. Before storing for longer than a few days, always empty the fuel tank (see chapter "Storing the Machine" in this manual). 001BA105 KN 1 2 3 a t = a : 2 You can run chains of different pitches on this chainsaw – depending on the chain sprocket ( see “ Specifications” ) : The chain pitch (1) must match the pitch of the sprocket and the guide bar (for Rollomatic). The drive link gauge (2) must match the bar groove width (3) . The pitch is marked on the chain sprocket and guide bar in inches (e. g. 3/ 8 or .325). The groove width is marked on the guide bar in millimeters (e.g. 1.6) . If non- matching components of the wrong pitch or drive link gauge are run together on the same machine they may be damaged beyond repair after a short period of operation.

This engine is certified to operate on unleaded gasoline and the STIHL two- stroke engine oil at a mix ratio of 50:1. Your two-stroke engine requires a mixture of brand- name gasoline and quality two- stroke air cooled engine oil. Use mid- grade unleaded gasoline with a minimum octane rating of 89 (R+M/ 2). If the octane rating of the mid- grade gasoline in your area is lower, use premium unleaded fuel. Fuel with a lower octane rating may...
