CHAIN TENSION
(including units with chain already installed)
NOTE: When adjusting chain tension,
make sure the chain brake nuts are finger
tight only. Attempting to tension the chain
when the chain brake nuts are tight can
cause damage.
Checking the tension:
Use the screwdriver end of the bar tool to
move the chain around the bar. If the chain
does not rotate, it is too tight. If too loose, the
chain will sag below the bar.

Adjusting the tension:
Chah_ 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 loosen-
ing the chain brake nuts and turning the ad-
justing screw t/4 of a turn while lifting up on
the bar.
• If chain is too tight, turn adjusflng screw 1/4
turn counterclockwise.
• If chain is too loose, turn adjusting screw
1/4 turn clockwise.

FUELING ENGINE
_, WARNIN G: Remove fuel cap slowly
when refueling.
This engine is certified to operate on unleaded
gasoline. Before operation, gasoline should be
mixed with a good quality synthetic 2-cycle
air-cooled engine oil designed to be mixed at a
ratio of 50:1, (A 50:1 ratio is obtained by mixing
2.6 ounces of oil with 1 gaflon of unleaded
gasoline). DO NOT USE automotive or boat
oil. These oils will cause engine damage.
When mixing fuel follow the instructions printed
on the container, Always read and follow the
safety rules listed under HANDLE FUELWITH
CAUTION,
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 oii will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar. Infreezing 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 lu-
brication.
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.
• Never use waste oil for bar and chain lu-
brication.
• Always stop the engine before removing
the oil cap.
