Chain Maintenance

MAINTENANCE AND REPAIR INSTRUCTIONS

WARNING: Unless you have experience and spe-

cialized training for dealing with kickback (see Safety Precautions), always use a low- kickback saw chain, which significantly reduces the danger of kickback. Low-kick- back saw chain does not completely elimi- nate kickback. A low-kickback or “safety chain”, should never be regarded as total protection against injury.

A low-kickback saw chain should always be used in con- junction with other kickback protection devices such as the Chain Brake®/Hand Guard furnished with your unit.

Always use a replacement saw chain designed as “low- kickback” or a saw chain which meets the low-kickback performance requirements of ANSI (American National Standards Institute).

A standard saw chain (a chain which does not have the kickback reducing guard links) should only be used by an experienced professional chain saw operator.

What is a Low-Kickback Saw Chain?

A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1.

By keeping the Chain Brake® and saw chain in good working condition and correctly serviced as recommended in this manual, you will be able to maintain the safety sys- tem of your chain saw over the life of the product.

Chain Tension

Check the chain tension frequently and adjust as often as necessary to keep the chain snug on the bar, but loose enough to be pulled around by hand.

Breaking in a New Saw Chain

A new chain and bar will need chain readjustment after as few as 5 cuts. This is normal during the break-in period, and the interval between future adjustments will begin to lengthen quickly.

Over a period of time, however, the moving parts of the saw chain will become worn, resulting in what is called CHAIN STRETCH. This is normal. When it is no longer possible to obtain correct chain tension adjustment, a link will have to be removed to shorten the chain. Take the

saw to a Sears or other qualified service dealer.

WARNING: Never have more than 3 links

removed from a loop of chain. This could cause damage to the sprocket.

Chain Lubrication

Always make sure the automatic oiler system is working properly. Keep the oil reservoir filled with a high quality Chain, Bar and Sprocket Oil.

Adequate lubrication of the bar and chain during cutting oper- ations is essential to minimize friction with the guide bar.

Never starve the bar and chain of lubricating oil. Running the saw dry or with too little oil will decrease cutting effi- ciency, shorten saw chain life, cause rapid dulling of chain, and lead to excessive wear of bar from overheating. Too little oil is evidenced by smoke or bar discoloration.

Chain Sharpening

Chain sharpening requires special tools to ensure that cut- ters are sharpened at the correct angle and depth. For the inexperienced chain saw user, we recommend that the saw chain be professionally sharpened by the nearest Authorized Service Center. If you feel comfortable sharp- ening your own saw chain, special tools are available from your Authorized Service Center.

WARNING: Never remove, mod- ify or make inopera-

tive any safety device furnished with your unit. The Chain Brake® / Hand Guard and low-kickback saw chain are major safety features provided for your protection.
