MAINTAINING THE GUIDE BAR

See Figure 58.

CAUTION:

Make sure the chain has stopped before you do any work on the saw.

Every week of use, reverse the guide bar on the saw to distribute the wear for maximum bar life. The bar should be cleaned every day of use and checked for wear and damage.

Feathering or burring of the bar rails is a normal process of bar wear. Such faults should be smoothed with a file as soon as they occur.

A bar with any of the following faults should be replaced:

nWear inside the bar rails that permits the chain to lay over sideways

nBent guide bar

nCracked or broken rails

nSpread rails

Lubricate guide bars weekly with a sprocket at their tip. Using a grease syringe, lubricate weekly in the lubricating hole. Turn the guide bar and check that the lubrication holes and chain groove are free from impurities.

MOUNTING THE SAFE-T-TIP NOSE GUARD

See Figures 59 - 60.

nStop the engine and disconnect the spark plug wire.

nMount the SAFE-T-TIP on the bar nose.

nFit the locking rivet or tab in the recessed hole in the guide bar.

nTighten the screw with wrench until snug.

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

MAINTAINING THE SAFE-T-TIP NOSE GUARD

See Figures 59 - 60.

CAUTION:

Make sure the chain has stopped before you do any work on the saw.

WARNING:

Although the guide bar comes with a SAFE-T-TIP anti- kickback device already installed, check the tightness of the mounting screw before each use.

Use the following instructions to tighten the mounting 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.
