WARNING Replacement parts for double-insulated appliance must be identical to the parts they replace. WARNING Use only STIHL replacement parts for maintenance and repair. Use of parts manufactured by others may cause serious or fatal injury. WARNING Never operate a chain saw that is damaged, improperly adjusted or not completely or securely assembled. Follow the maintenance and repair instructions in the appropriate section of your instruction manual, especially those in the chapters "Mounting the Bar and Chain", "Maintaining and Sharpening" and "Chain Brake". WARNING Always stop the motor, disconnect the plug from the power supply and ensure that the chain is stopped before making any adjustments, maintenance or repair work, changing the saw chain or cleaning the saw. Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed at your STIHL service shop only. Keep the chain, bar and sprocket clean; replace worn sprockets or chains. Keep the chain sharp. You can spot a dull chain when easy-to-cut wood becomes hard to cut and burn marks appear on the wood. Keep the chain at proper tension. Tighten all nuts, bolts and screws before each use. Only authorized personnel may replace the power supply cord. A damaged power supply cord must be replaced by an identical STIHL replacement part. WARNING In order for the chain brake on your STIHL chain saw to properly perform its function of reducing the risk of kickback and other injuries, it must be properly maintained. Like an automobile brake, a chain saw 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 drum must be kept free of dirt, grease and other foreign matter which may reduce friction of the band on the drum. English For these reasons, each STIHL chain saw 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 chain saw should also be returned immediately for maintenance whenever the brake system cannot be thoroughly cleaned or there is a change in its operating characteristics. Additionally, the daily maintenance schedule for your chain saw set forth in your instruction manual should be strictly followed. Store chain saw in a dry place and away from children. It should have the scabbard mounted or be in a carrying case. MSE 170 C, MSE 210 C 21
