Craftsman 316.79246 - Manual (Page 8)

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, it is recommended
to purchase a replacement chain at Sears or other qualified service
dealer have this repair performed.
CLEANING
• 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.
STORAGE
Wait for the engine to cool down. Drain the oil 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.
4. On the bar pad use a soft
wire small enough to
insert into the oil
discharge hole, scrape
any saw dust or debri
away. (Fig. 14)
5. Reinstall the bar, chain,
chainguard, screw, and
bar retaining nuts. Refer
to Saw Chain
Replacement /
Installation.
CHAIN MAINTENANCE
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 pole saw over the life of the product.
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.
MAINTENANCE AND REPAIR INSTRUCTIONS
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.
WARNING: Never remove, modify or make inoperative any
safety device furnished with your unit. The low-kickback saw
chain is a major safety feature 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.
WARNING: Never use a loop of chain that has more than
3 links removed from it. This could damage the sprocket.
