MAINTENANCE Installing the Safe-T-Tip® Nose Guard CAUTION: Check that the switch is in the ” stop position before you do any work on the saw. Air Filter Loosen the two air filter screws ( G ) by turning counterclockwise, remove air filter cover ( H ) and check the air filter ( I ) each day; shake the filter and clean with a soft brush. If heavily contami- nated, clean with soapy water, rinse, and dry thoroughly prior to installing. Reinstall the air filter. Place the air filter cover onto the chain saw. Tighten the two air filter cover screws securely.
WARNING Although the guide bar comes with a SAFE-T-TIP® anti- kickback device already installed, you need to check the tightness of the mounting screw (A) before each use. WARNING Never run the engine without the air filter, serious damage could result. Tighten the mounting screw ( A ) of the nose guard as instructed below. These are specially hardened screws. If the screw cannot be installed tightly, replace both the screw and the SAFE- T-TIP® before further operation. Do not replace with an ordinary screw. 1. In addition to preventing chain contact with solid objects at the nose of the bar, the SAFE-T-TIP® also helps keep the chain away from abrasive surfaces such as the ground.
Keep it on the right hand side of the bar ( B ), where it will be between the chain and the ground during flush-with-ground cutting. 2. The mounting screw requires a 3/8" wrench (or adjustable wrench) to achieve the recommended tightness of 70-100 inch-pounds (8-11 Nm). A tightness within this range can be achieved by the following method. a) Mount the SAFE-T-TIP® on the bar nose. (See illustration for details.) Locking rivet or tab fits in square hole in guide bar ( C ). Tighten the screw with your finger. b) From the finger-tight position ( D ), tighten the screw an additional 1/2 - 3/4 of a turn using a wrench ( E ).
