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 chain adjust-
ment tool (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.

Chain tension is very important. Chain
stretches during use. This is especially true
during the first few times you use your saw.

the adjusting screw 1/4 of a turn while lifting

FUELING & LUBRICATION
WARNING:
Remove fuel cap slow-
ly when refueling.
FUELING ENGINE
This engine is certified to operate on
unleaded gasoline. Before operation,
gasoline must be mixed with a good quality
2-cycle air-cooled engine oil. We
recommend Husqvarna
R
brand oil. If you do
not use this oil, use a good quality 2-cycle
air-cooled oil designed to be mixed at a ratio
of 40:1. A 40:1 ratio is obtained by mixing
0,125 liter of oil with 5 liters 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
FUEL WITH 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 oil will cause overheating
shown by smoke coming from the chain and/
or discoloration of the bar.
Only use Bar and Chain Oil for bar and chain
lubrication.
