Adjusting the tension:
Chain tension is very important.
Chain
stretches during use. This is especially true
during the first few times you use your saw.
Always check chain tension each time you
use and refuel your saw.
You can adjust the chain tension by loosening
the bar clamp nuts and turning the adjusting
screw 1/4 of a turn while lifting up on the bar.
S
If chain is too tight, turn adjusting
screw 1/4 turn counterclockwise.
S
If chain is too loose, turn adjusting
screw 1/4 turn clockwise.

FUELING & LUBRICATION
FUELING ENGINE
WARNING:
Remove fuel cap slowly
when refueling.
This engine is certified to operate on
unleaded
gasoline.
Before
operation,
gasoline must be mixed with a good quality
synthetic 2-cycle air-cooled engine oil
designed to be mixed at a ratio of 40:1. A
40:1 ratio is obtained by mixing 3.2 ounces of
oil with 1 gallon of unleaded gasoline. DO
NOT USE automotive oil or boat oil. These
oils will cause engine damage. When mixing
fuel, follow instructions printed on container.
Once oil is added to gasoline, shake
container momentarily to assure that the fuel
is thoroughly mixed. Always read and follow
the safety rules relating to fuel before fueling
your unit.
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 little 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
Husqvarna
bar and chain oil is rec-
ommended to protect your unit against exces-
sive wear from heat and friction.
Husqvarna
oil
resists high temperature thinning.
If
Husqvarna
bar oil is not available, use a good
grade SAE 30 oil.
S
Never use waste oil for bar and chain lu-
brication.
S
Always stop the engine before removing
the oil cap.
IMPORTANT
Experience indicates that alcohol--blended
fuels (called gasohol or using ethanol or
methanol) can attract moisture which leads
to separation and formation of acids during
storage. Acidic gas can damage the fuel
system of an engine while in storage. To
avoid engine problems, the fuel system
should be emptied before storage for 30
days or longer. Drain the gas tank, start the
engine and let it run until the fuel lines and
carburetor are empty. Use fresh fuel next
season. See STORAGE section for addi-
tional information.
