CHAIN MAINTENANCE
WARNING:
Unless you have experience and
specialized training for dealing with kickback (see
Important Safety Instructions), 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 in conjunction
with other kickback protection devices such as the hand guard,
which is furnished with your unit.
Always use a replacement saw chain designed as "low-kickback"
or a saw chain which meets the low-kickback performance.
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.
Low-Kickback Saw Chain
A low-kickback saw chain is a chain which has met the kickback
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 polesaw over the life of the
product.
WARNING:
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:
Ensure that the unit is off and the spark
plug is disconnected (for gas powerheads) when
working on the saw chain. Wear heavy duty gloves too.

MAINTENANCE AND REPAIR INSTRUCTIONS

SPECIFICATIONS

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. Refer to 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.
WARNING:
Never use a loop of chain that has more
than 3 links removed from it. This could damage the
sprocket.

CLEANING AND STORAGE

• Slacken the chain if you have retensioned it at operating
temperature during cutting work.
• The chain contracts as it cools down. If it is not slackened, it
may damage the gearbox and bearings.
Storing the Machine for a Short Period
Wait for the engine to cool down. Drain the fuel tank and store the
machine in a dry place well away from sources of ignition until you
need it again.
• Attach the transport guard to the bar/chain before storing the
unit.
• Store the unit in a dry, high and/or locked location, out of the
reach of children and other unauthorized persons.
Long-Term Storage
• Remove the saw chain and guide bar, clean them, and spray
them with corrosion inhibiting oil.
• Attach the transport guard to the bar/chain before storing.
