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-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 per- formance 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.

WARNING / CAUTION

Never have more than three (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 tank filled with Genuine Factory Parts Chain, Bar and Sprocket Oil.

Adequate lubrication of the bar and chain during cutting operations 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 rapid cutting efficiency, shorten saw chain life, cause rapid dulling of the chain, and lead to excessive wear of the bar from overheat- ing. Too little oil is evidenced by smoke or bar discoloration.

WARNING

SERVICING A DOUBLE INSULATED APPLIANCE

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

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

1.	Place switch in OFF position and unplug the power
	supply before the appliance 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

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.

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.

WARNING

Never remove, modify or make inoperative any safety device furnished with your unit. The CHAIN BRAKE®/Hand Guard and low-kickback saw chain are major safety fea- tures 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 3-4, 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 len- gthen 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 nearest Authorized Service Center to have this repair performed.

	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.
