BAR
AND
CHAIN
LUBRICATION
The bar and chain require continuous
lubri-
cation.
Lubrication
is provided
by the auto-
matic oiler system when the oil tank is kept
filled. Lack of oil will quickly
ruin the bar and
chain.
Too littIe oil will cause
overheating
shown by smoke coming from the chain and/
or discoloration
of the bar.
In freezing
weather oil will thicken,
making it
necessary
to thin bar and chain
oil with a
small amount (5 to 10%) of #1 Diesel Fuel or
kerosene.
Bar and chain
oil must be free
flowing for the oil system to pump enough oil
for adequate
lubrication.
Genuine
Pou]an _; barand
chain oil is recom-
mended
to protect
your unit against
exces-
sive wear from heat and friction.
Poulan
n;
oil resists high temperature
thinning.
If Poulae _; bar and chain oil is not availaMe,
use a good grade SAE 30 oil.
• Never use waste oil for bar and chain lubri-
cation.
• Always
stop the engine
before removing
the oil cap,
