3 - ASSEMBLY INSTRUCTIONS

CAUTION

A new saw chain stretches, requiring adjustment after as few as 5 cuts. This is normal with a new chain, and the interval between future adjustments will lengthen quickly.

CAUTION

If saw chain is TOO LOOSE or TOO TIGHT, the sprocket, bar, chain, and crankshaft bearings will wear more rapidly. Study Figure 3-4B for information concerning correct cold tension (A), correct warm tension (B), and as a guide for when saw chain needs adjustment (C).

To Test CHAIN BRAKE®:

1.The CHAIN BRAKE® is DISENGAGED (chain can move) when BRAKE LEVER IS PULLED BACK AND LOCKED. Be sure the chain brake latch is in the OFF position. (Figure 3-5A).

2.The CHAIN BRAKE® is ENGAGED (chain is stopped) when brake lever is in forward position and the chain brake latch is in the ON position. You should not be able to move chain (Figure 3-5B).

NOTE: The brake lever should snap into both positions. If strong resistance is felt, or lever does not move into either position, do not use your saw. Take it immediately to an Authorized Service Center for repair.

3-5. CHAIN BRAKE® MECHANICAL TEST

Your chain saw is equipped with a CHAIN BRAKE® that reduces possibility of injury due to kickback. The brake is activated if pressure is applied against brake lever when, as in the event of kickback, operator’s hand strikes the lever. When the brake is actuated, chain movement stops abruptly.

WARNING

The purpose of the CHAIN BRAKE® is to reduce the possi- bility of injury due to kickback; however, it cannot provide the intended measure of protection if the saw is operated carelessly.

Always test the CHAIN BRAKE® before using your saw and periodically while on the job.
