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.
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.
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
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.

There may be other quality equivalent replacement compo-
nents for achieving kickback protection.
