MAINTENANCE

Use the following instructions to tighten the mount- ing screw of the nose guard. These are specially hardened screws. If you cannot install the screw tightly, replace both the screw and the SAFE-T-TIP®before further operation.

NOTE:  Do not replace the screw with an ordinary screw. Use only identical replacement parts from the manufacturer when replacing parts.

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 where it will be between the chain and the ground during flush with ground cutting.

The mounting screw requires a 5/16 in. wrench (or adjustable wrench) to achieve the recommended torque of 35 to 45 in.lb. A torque within this range can be achieved by using the following method.

nTighten the screw with wrench until snug.

nFrom the snug position, tighten the screw an additional 3/4 of a turn using a wrench.
