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. ( 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 MTD Authorized
Service Center to have this repair performed.
PREVENTATIVE MAINTENANCE
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 sup-
ply before the appliance is serviced, cleaned, or mainte-
nance 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 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 MTD 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.
Never have more than 3
links removed from a
loop of chain this could
cause damage to the sprocket.
WARNING/
CAUTION:
Never remove, modify
or make inoperative
any safety device furnished with your unit.
The Hand Guard and low-kickback saw
chain are major safety features provided for
your protection.
WARNING:
Always wear heavy
duty protection work
gloves and disconnect the extension cord
when working on the saw chain.
