FUELING & LUBRICATION
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 POULAN/WEED EATERR
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 3.2 ounces of oil with 1
gallon of unleaded gasoline). When mixing
fuel follow the instructions printed on the
container. 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 POULAN or POULAN PRO bar
and chain oil is recommended to protect your
unit against excessive wear from heat and
friction. POULAN or POULAN PRO oil
resists high temperature thinning. If
POULAN or POULAN PRO bar and chain oil
is not available, use a good grade SAE 30 oil.
S
Never use waste oil for bar and chain lubri-
cation.
S Always stop the engine before removing
the oil cap.
MPORTANT
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.
STARTING
WARNING: he chain must not move
when the engine runs at idle speed. If the
chain moves at idle speed refer to CARBU-
RETOR ADJUSTMENT within this manual.
Avoid contact with the muffler. A hot muffler
can cause serious burns.
To stop the engine move the ON/STOP
switch to the STOP position.
To start the engine hold the saw firmly on
the ground as illustrated. Make sure the
chain is free to turn without contacting any
object.
Hold saw firmly while pulling starter rope
Use only 15”---18” of rope per pull.
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
back. Hold the handle and let the rope rewind
slowly.
NOTE: Do not attempt to cut material with
the fast idle lock button in the locked position.
STARTING A COLD ENGINE (or
warm engine after running out of
fuel).
S Move ON/STOP switch to the ON position.
S Pull choke knob out to the full extent.
S Slowly press primer bulb 6 times.
S Squeeze and hold throttle trigger. With
thumb press fast idle lock down; then re-
lease throttle trigger.
S Sharply pull the starter rope handle 5 times
with your right hand.
S Push the choke knob in completely (to the
OFF position); pull the starter rope until the
engine starts.
