BEFORE STARTING ENGINE
WARNING; Experience indicates that
alcohol blended fuels (called gasohol or
those 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. Start engine and let it run until fuel
lines and carburetor are empty. Use
carburetor bowl drain to empty residual
gasoline from float chamber (See figure in
Storage section, page 16). Use fresh fuel
next season, (See Storage Instructions on
page t6 for additional information).
TO USE AUGER PROPEL ACTION
, Squeeze the auger control bar down
against the upper handle to al!ow the
auger to turn.
• To propel forward, raise the handle to
allow the rubber auger blades to contact
the ground (See figure below).

FILL GAS
The two cycle engine used on this snow
thrower requires a mixture of gasoline and
oil for lubrication of the bearings and other
moving parts. The correct fuel mixture ratio
is 40:1 (3.2 oz. oil per gallon of gas - see
Fuel Mixture Chart). Gasoline and oil must
be pre-mixed in a clean gasoline container,
Always use fresh, clean, unleaded gasoline.

WARNING: Gasoline is flammable and
caution must be used when handling or
storing it. Do not fill fuel tank while snow
thrower is running, hot, or when snow
thrower is in an enclosed area. Keep away
from open flame, electrical spark, and do
not smoke while filling the fuel tank. Never
fill fuel tank completely; but fill the tank to
within 1t4-1/2 inch from the top to provide
space for expansion of fue!. Always fill fuel
tank outdoors and use a funnel or spout to
prevent spilling. Make sure to wipe up any
spilled fuel before starting the engine. Store
gasoline in a clean, approved container,
and keep the cap in place on the container.
Keep gasoline in a cool, well ventilated
place; never in the house. Never buy more
than a 30 day supply of gasoline to ensure
volatility. Gasoline is intended to be used as
a fuel for internal combustion engines;
therefore, do not use gasoline for any other
purpose. Since many children like the smell
of gasoline, keep it out of their reach
because the fumes are dangerous to
inhale, as well as being explosive.

SNOW THROWING TIPS
, This snow thrower will propel itself
for._ard when the handle is raised
enough to cause the auger blades to
contact the ground. The auger should
stop when auger control bar is released.
If it does not, refer to Adjust Auger
Control Cable paragraph on page !2.
• For most efficient snow throwing, turn the
discharge chute deflector to throw snow
downwind, and slightly overlap each
swath. In light snow take up to a full cut
and in heavy snow take less than a full
cut.
o The distance snow will be discharged can
be adjusted by moving the discharge
chute deflector. Raise the deflector for
more distance or lower the deflector for
less distance.
should go. When it appears that the wet,
packed snow is causing the auger to slow
down and the chute to clog, back off and
begin a series of short jabs into the snow,
These short back and forth, 4 to 6 inch,
jabbing motions wilt "belch" the snow
from the chute°
SNOW BANKS AND DRIFTS
• In snow of greater depth than the unit,
use the jabbing technique described
above. Turn the discharge chute away
from the snow bank. More time will be
required to remove snow of this type than
level snow.
PRODUCT SPECIFICATIONS
HORSE POWER: 5HP
DISPLACEMENT: 8.46 cuein.
• In windy conditions, lower the chute
deflector to direct discharged snow close
to the ground where it is less likely to
blow into unwanted areas.
o Keep the area to be cleared free of
stones, toys and other foreign objects for
safety and to prevent damage to the
snow thrower.
Do not use the auger propelling feature
when clearing gravel or crushed rock
driveways. Move the handle down to
raise the auger slightly.
The allowable forward speed of the snow
thrower is dependent on the depth and
weight of the snow. Experience wilt
establish the most effective method of
using the snow thrower under different
conditions.
DRY AND AVERAGE SNOW
• Snow up to eight inch depth can be
removed rapidly and easily by walking at
a moderate rate. For snow or drifts of a
greater depth you may find it desirable to
slow your pace to allow the discharge
chute to dispose of the snow as rapidly
as the auger receives the snow.
• Plan to have the snow discharged in the
direction the wind is blowing_
WET PACKED SNOW
• Move slowly into snow of this condition.
