MAINTENANCE AND REPAIR INSTRUCTIONS

CHAIN MAINTENANCE

WARNING: Unless you have experience and

specialized training for dealing with kickback (see Important Safety Instructions), always use a low-kickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not completely eliminate 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 conjunction with other kickback protection devices such as the hand guard, which is furnished with your unit.

Always use a replacement saw chain designed as “low- kickback” or a saw chain which meets the low-kickback performance.

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.

Low-Kickback Saw Chain

A low-kickback saw chain is a chain which has met the kickback performance requirements of ANSI B175.1. Do not use other replacement chain unless it has met these requirements for your specific model.

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

WARNING: Never remove, modify or make

inoperative any safety device furnished with your unit. The low kick back saw chain is a major safety feature provided for your protection.

WARNING: Ensure that the unit is off and the spark

plug is disconnected (for gas powerheads) when working on the saw chain. Wear heavy duty gloves too.

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. Refer to Saw Chain Tension Adjustment.

Breaking in a New Saw Chain

A new chain and bar will need 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. See your TrimmerPlus Authorized Service Center to have this repair performed.

WARNING: Never use a loop of chain that has more

than 3 links removed from it. This could damage the sprocket.
