6-2. CHAIN MAINTENANCE INSTRUCTIONS

WARNING

Unless you have experience and specialized training for dealing with kickback (see Safety Precautions), always use a low-kickback saw chain, which significantly reduces the danger of kickback. Low-kickback saw chain does not com- pletely eliminate kickback. A low-kickback or “safety chain”, should never be regarded as total protection against injury. A low kick saw chain should always be used in combination with other kickback protection devises such as a hand guard and reduced kickback guide bar supplied with the your unit.

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

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 kick- back 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 hand guard, reduced kickback guide bar and low kick back saw chain are major safety features provided for your protection.

WARNING

Always wear heavy duty protection work gloves and discon- nect the extension cord when working on the saw chain.

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. (See Section 3-5, Saw Chain Tension Adjustment).

BREAKING IN A NEW SAW CHAIN

A new chain and bar will need readjustment after as few as five (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 McCulloch Authorized Service Center to have this repair performed.

WARNING / CAUTION

Never have more than three (3) links removed from a loop of chain this could cause damage to the sprocket.

WARNING

SERVICING A DOUBLE INSULATED CHAIN SAW

In this double insulated chain saw, 2 systems of insulation, instead of grounding, are provided. No grounding means is provided on a double insulated chain saw, nor should a means for grounding be added to the chain saw. No serv- iceable parts are inside. A double insulated chain saw is marked with the words, “DOUBLE INSULATION” or “DOU-

BLE INSULATED”. The symbol (square within a square) may also be marked on the chain saw.

1.Place switch in OFF position and unplug the power supply before the chain saw is serviced, cleaned, or maintenance is performed.

2.Keep the air intake clean and air vents free of debris to avoid overheating the motor.

3.Clean with a damp sponge and mild soap. Do not squirt with a water hose or douse with water or other liquids.

4.Inspect the saw chain for proper tension before each use and frequently during cutting. Sharpen as required.

5.Clean the guide bar and bar pad to ensure free path for oil.

6.Turn the bar over after each use to achieve even wear.

7.No motor lubrication is necessary. The motor is equipped with lifetime lubricated bearings.

8.If the saw does not operate, turn switch to OFF posi- tion and disconnect the extension cord, first from the power supply, then from the saw. Check the power supply for blown fuses or tripped circuit breakers. If it still does not operate, contact the McCulloch Product Service Department, through the toll-free number list- ed on the back cover of this manual, for service infor- mation. Do not attempt to repair it yourself. No serv- iceable parts are inside.
