Stihl MSA 200 C-BQ Instruction Manual - Page 24

English WARNING In order to reduce the risk of personal injury, never stand directly behind the tree when it is about to fall, since part of the trunk may split and come back towards the operator (barber-chairing), or the tree may jump backwards off the stump. Always keep to the side of the falling tree. When the tree starts to fall, withdraw the bar, shut off the engine and walk away on the preplanned escape path. Watch out for falling limbs. WARNING Be extremely careful with partially fallen trees which are poorly supported. When the tree hangs or for some other reason does not fall completely, set the saw aside and pull the tree down with a cable winch, block and tackle or tractor. If you try to cut it down with your saw, you may be injured. MAINTENANCE, REPAIR AND STORING If you make a warranty claim for a component which has not been serviced or 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 section of your instruction manual. Please also refer to the maintenance chart in this manual. Always switch off the motor, move front hand guard to ƒ, remove the battery from the power tool and make sure that the cutting tool is stopped before carrying out any maintenance or repair work, such as replacing the cutting attachment, or cleaning the power tool. This avoids the risk of the motor starting unintentionally. WARNING 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 saw chains. 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. Always replace the chain, guide bar and sprocket as necessary. Tighten all nuts, bolts and screws after each use. 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 chain sprocket 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 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. Regularly check the electrical contacts and ensure that the insulation of the power cord and plug of the charger is in good condition and shows no sign of aging (brittleness). 22 MSA 160 C, MSA 200 C
