sion.”

—Proper lubrication. See “Bar and Chain Lubricant.”

— Regular maintenance as described in this sec

tion.

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.

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.
