Chain Maintenance
Unless you have experience and specialized training for dealing with kick-
back (see Safety Precautions), 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. Always use a replace-
ment 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 perfor-
mance requirements of ANSI B175.1.
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.
Never remove, modify or make inoperative any safety device furnished
with your unit. The low-kickback saw chain and bar are major safety fea-
tures provided for your protection.
Always wear heavy duty protection work gloves and disconnect 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 Assembly)
Breaking in a New Chain Saw
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 adjust-
ments 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, listed under "SAWS" in your Telephone
Directory Yellow Pages, to have this repair performed.
Never have more than 3 links removed from a loop of chain. This could
cause damage to the sprocket.

Maintenance

Chain Lubrication:
Adequate lubrication of the saw chain during cutting operations is essential
to minimize friction with the guide bar. Your chain saw is equipped with a
manual oiler. The oil tank level can be checked in the inspection slot provid-
ed on the left side of the saw. (see chain and bar Lubrication)
CAUTION: Never starve the bar and chain of oil. Running the saw
DRY or with TOO LITTLE OIL will decrease cutting efficiency, shorten
saw chain life and cause rapid dulling of the chain and overheating which
dulls the chain and wears the bar. When this occurs, smoke or bar discol-
oration can be seen.
Never cut tree limbs while standing on tree trunk.
Preventative Maintenance
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 serviceable parts are inside. A double insulated appliance
is marked with the words, "DOUBLE INSULATION" or "DOUBLE INSU-
LATED." The symbol
the appliance.
Servicing a Double Insulated 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 over-
heating 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 frequent-
ly 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 OFF position 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 listed on the back cover of
this manual, for service information. Do not attempt to repair it yourself.
No serviceable parts are inside.
