BAR AND CHAIN LUBRICATION
The bar and chain require continuous lubri-
cation. Lubrication is provided by the auto-
matic oiler system when the oiltank is kept
filled. Lack of oil will quickly ruin the bar and
chain. Too little oil will cause overheating
shownby smokecomingfromthechainand/
or discoloration of the bar.
In freezing weather oil will thicken, making it
necessary to thin bar and chain oil with a
small am ount(5 to10%) of#1Diesel Fuelor
kerosene. Bar a nd chain oil must be free
