Stihl HT 101 Product Instruction Manual - Page 15

B = Pushback B Pushback occurs when the chain on the top of the bar is suddenly stopped when it is pinched, caught or encounters a foreign object in the wood. The reaction of the chain may drive the saw rapidly straight back toward the operator. Pushback frequently occurs when the top of the bar is used for cutting. To Avoid Pushback 1. Be alert to forces or situations that may cause material to pinch the chain at the top of the bar. 2. Do not cut more than one limb at a time. 3. Do not twist the bar when withdrawing it from an underbuck cut because the chain can pinch. MAINTENANCE, REPAIR AND STORING Maintenance, replacement, or repair of the emission control devices and systems may be performed by any nonroad engine repair establishment or individual. However, if you make a warranty claim for a component which has not been serviced or 001BA038 KN maintained properly or if nonapproved replacement parts were used, STIHL may deny coverage. Warning! Use only identical STIHL replacement parts for maintenance and repair. Use of non-STIHL parts may cause serious or fatal injury. Strictly follow the maintenance and repair instructions in the appropriate sections of your instruction manual. Please refer to the maintenance chart in this manual. Warning! Always stop the engine and make sure that the chain is stopped before doing any maintenance or repair work or cleaning the power tool. Do not attempt any maintenance or repair work not described in your instruction manual. Have such work performed by your STIHL servicing dealer only. Wear gloves when handling or performing maintenance on the cutting attachment. English Warning! Use the specified spark plug and make sure it and the ignition lead are always clean and in good condition. Always press spark plug boot snugly onto spark plug terminal of the proper size. (Note: If terminal has detachable SAE adapter nut, it must be securely attached.) A loose connection between spark plug terminal and the ignition wire connector in the boot may create arcing that could ignite combustible fumes and cause a fire. Warning! Never test the ignition system with the ignition wire boot removed from the spark plug or with a removed spark plug, since uncontained sparking may cause a fire. Warning! Do not operate your power tool if the muffler is damaged, missing or modified. An improperly maintained muffler will increase the risk of fire and hearing loss. If your muffler was equipped with a spark-arresting screen to reduce the risk of fire, never operate your power tool if the screen is missing or damaged. Remember that the risk of forest fires is greater in hot or dry weather. HT 100, HT 101, HT 130, HT 131 13
