MAINTAINING THE GUIDE BAR

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. See Figure 68. 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:

Wear inside the bar rails that permits the chain to lie over sideways

Bent guide bar Cracked or broken rails Spread rails

In addition, lubricate guide bars with a sprocket at their tip weekly. Using a grease syringe, lubricate weekly in the lubricating hole. See Figure 68.

Turn the guide bar and check that the lubrication holes and chain groove are free from impurities.

MAINTAINING THE SAFE-T-TIP®NOSE GUARD

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- kick-back device already installed, be sure to check the tightness of the mounting screw before each use.

Tighten the mounting screw of the nose guard as instructed below. These are specially hardened screws. If you cannot install the screw tightly, replace both the screw and the SAFE-T-TIP®before further operation. Do not replace the screw with an ordinary screw.

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. spanner or adjustable spanner to achieve the recommended tightness of 4-5 Nm (35 to 45 in. lb.). A tightness within this range can be achieved by using the following method. See Figure 69.

1.Tighten the screw with your finger.

2.Tighten the screw an additional three-quarters of a turn using a spanner.
