4-2. TO STOP MOTOR The saw motor will automatically stop when the trigger is released. The LOCK/ OFF button will have to be depressed and the trigger squeezed to restart the motor. 4.3. CHAIN AND BAR LUBRICATION Adequate lubrication of the saw chain during cutting operations is essential to minimize friction with the guide bar. Your chain saw is equipped with an automatic oiler system. The oiler automatically delivers the proper amount of oil to the bar and chain. There is no flow adjustment. The oil tank level can be checked in the inspection slot (A) provided on the right side of the saw. Tank is full when oil is at the top of the slot (Figure 4.3A). CAUTION Never starve the bar and chain of lubrication oil. Running the saw DRY or with TOO LITTLE OIL will decrease cutting efficiency, shorten chain saw life, and cause rapid dulling of the chain and excessive wear of the bar from overheating. Too little is evidenced by smoke or bar discoloration. NOTE: The saw chain stretches during use, particularly when it is new, and occasional adjustment will be needed. A new chain requires more frequent adjustment during the break-in period. This is normal. See Section 3.4, Saw Chain Tension Adjustment instructions. WARNING / CAUTION A loose chain can jump off the bar while you are cutting, as well as wear the bar and chain. A chain that is too tight can damage the saw. Either situation, chain too loose or too tight, could cause serious personal injury. against the guard or when, in the event of kickback, the operator's hand strikes the lever. When the CHAIN BRAKE® is activated, chain movement abruptly stops and the power supply to the motor is immediately cut off. The purpose of the CHAIN BRAKE® is to reduce the possibility of injury due to kickback. The CHAIN BRAKE® cannot, however, provide the measure of intended protection if the saw is carelessly operated. The CHAIN BRAKE® is disengaged (chain can move) when the brake is pulled back and locked. This is the normal running position (Figure 4-4A). The CHAIN BRAKE® is engaged (chain cannot move) when the brake is in forward position (Figure 4-4B). NOTE: The motor will not start if the CHAIN BRAKE® is in the engaged position. CAUTION The CHAIN BRAKE® should not be used for starting and stopping the saw during normal operation. 4-4A 4-4B 4-3A 4-4. CHAIN BRAKE® I HAND GUARD This Poulan chain saw is equipped with chain brake/hand guard. The Hand Guard protects your left hand in the event it slips off the front handle. The CHAIN BRAKE® is a safety feature which is activated if pressure is applied CHAIN BRAKE® TEST Before cutting with your saw, the CHAIN BRAKE® should be tested as follows: A. Make sure the CHAIN BRAKE® is disengaged (Figure 4-4A). B. Place the saw on a firm, flat, dry surface that is clear of any debris. Do not let the saw come in contact with any objects. C. Plug the unit into the power source. D. Grasp the front handle (not the CHAIN BRAKE®/Hand Guard Lever) with your left hand. Thumb and fingers should encircle the handle. 12
