Useful Information - Oregon CHAINSAW Maintenance And Safety Manual

Cutting frozen wood will cause rapid wear and
possible breakage around the rear rivet hole of
cutters. Follow the steps below to keep cold-weather
wear to a minimum.
OIL
Dilute bar-chain oil 25 percent with clean kerosene or diesel oil. Use
twice as much of this diluted oil during operation, and be certain your
chain is receiving oil from the saw.
TENSION
Keep your chain correctly tensioned.
Check and adjust often.
CUTTERS
Keep cutters sharp. Touch up every hour, more often if needed.
Do not force dull chain to cut.
DEPTH GAUGES
Check and adjust your cutter's depth gauges at every sharpening.
BAR
Keep the bar groove clean and the oil hole open.
Turn symmetrical* bars over to equalize rail wear.
*Do not turn Guard Tip® bars over.
DRIVE SPROCKET
Replace the sprocket after every three chains, or sooner.
