Poulan 3300 - Manual (Page 16)

MAINTENANCE
A good maintenance program of regular inspection
and care will increase the service life and help to main­
tain the safety and performance of your saw.
• Check the saw for loose bolts, screws, nuts and fit­
tings regularly. Lxxjse fasteners can cause an unsafe
condition as well as damage to your saw. Tools required
are described in "Preparing Your Saw For Use.’’
• Make all adjustments or repairs (except car­
buretor adjustments) with:
— spark plug wire disconnected
—engine cool as opposed to a unit that has Just
been run.
A
WARNING
Have all chain saw service performed by a qualified
service dealer with the exception of the items listed
In the maintenance section of this manual.
Increase the service life of your Guide Bar and
Chain by:
—Using the saw properly and as recommended
in this manual.
—Maintaining correct chain tension. See “Chain Ten­
sion.”
—Proper lubrication. See “Bar and Chain Lubricant.”
— Regular maintenance as described in this sec­
tion.
1 CHAIN MAINTENANCE
• Sharpen the chain when:
— Wood chips are small and powdery. Wood
chips made by the saw chain should be
about the size of the teeth of the chain.
— Saw has to be forced through the cut.
— Saw cuts to one side.
ICAUTIOI^ Always wear gloves when hand­
ling the chain. The chain can be sharp enough to
cut you even though it may be too dull to cut
wood.
