FUELING ENGINE
_h',WARNING:
Removefuel
capslowly
when refueling.
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 designed to be
mixed at a ratio of 50:1.
(A 50:1 ratio is
obtained by mixing 2.5 ounces ofoil with 1
gallon of unleaded gasoline). DO NOT USE
automotive or boat oil. These oils will cause
enginedamage.
When mixing fuel followthe
instructions printed on the containe_ 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.
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.
• Never use waste oil for bar and chain lu-
brication.
• 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.
A
4_, WARNING:
The chain must not move
when the engine runs at idle speed, if the chain
moves at idle speed refer to CARBURETOR
ADJUSTMENT within this manual. Avoid con-
tact with the muffler. A hot muffler can cause
serious bums.
To stop the engine move the switch to the
STOP position.
To start the engine hold the saw firmly on
the ground as illustrated below. Make sure
the chain is free to turn without contacting
any object.
Use only 15"- 18" of rope per pull.
Hold saw firmly while pulling starter rope.
Important
points
to remember
When pulling the starter rope, do not use the
full extent of the rope as this can cause the
rope to break. Do not let starter rope snap
