BEFORE STARTING ENGINE

WARNING: Experience indicates that

alcohol blended fuels (called gasohot 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 15). Use fresh fuel
next season.= (See Storage Instructions on
page 15 for additional information).

Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.

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.

GASOLINE AND OIL MIXTURE

Mix gasoline and oil as follows:

• Pour 1 U.S. quart of fresh, clean,

unleaded automotive gasoline to a gallon
gasoline container.

o Add 3.2 oz of clean, high quality,

Craftsman two-cycle oil into the gasotine
container (One 3.2 ounces of oil pro-
vided).

DO NOT FILL THE FUEL TANK WITH GASOLINE THAT DOES NOT HAVE OIL MIXED IN IT.

IMPORTANT: Do not use outboard motor
oil or automobile oils, such as SAE 30 oil,
or multi-viscosity oits, such as 10W-30 or

1oW-40.

• Reinstall the cap on the gasoline
container and shake conlainer vigorously

so the oil mixes with the gasoline

° Add an additional 3 U.S. quarts of

gasoline to the gallon container and
shake the container again.

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 1/4-1/2 inch from the top to provide
space for expansion of tuel. Always flit 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 1obe used as
a fuel for internal combustion engines;
therefore, do not use gasoline for any other
purpose. Since many children like the small
of gasoline, keep it out of their reach
because the fumes are dangerous to
inhale, as well as being explosive.

TO STOP ENGINE

• To stop the engine, turn the key to OFF
and remove key. Keep key in a safe

place. The engine will not start without the
key. See figure on next page.

TO START ENGINE (RECOIL START)

Before starting the engine, be certain that

you have read and understood all the
instructions on the preceding pages.

COLD START

Insert the key and turn ON.
Move the choke control to the FULL
position.

Push the primer button while covering the
vent holes as follows: (Remove finger
from primer button between primes).

Do not prime if temperature is above

50°F.

Two times iftemperature is 50 ° F to t5°F.
Four times if temperature is below 15°Fo

• Pull the starter handle with a smooth rapid
movement. Do not allow the starter rope

to snap back. Rewind smoothly while

holding the starter handle. If the engine

fires but does not start, pull the starter

handle until the engine starts_

• After three pulls, repeat the priming and
pulling steps again.

• As the engine warms up and begins to

operate evenly, move the choke control
slowly to the OFF position. If the engine

falters, return to i/2 choke until it runs
smoothly, then move to OFF position.

NOTE: Allow engine to warm up for a few
minutes before using snow thrower, as the
engine will not develop full power until it
reaches operating temperature_

WARM START

o Be sure the choke is in the OFF poSi-

tion and pull the siarter handle until the

engine starts.

./_ CAUTION Never run engine indoors
or in enclosed, poorly ventilated areas.
Engine exhaust contains carbon monoxide,
an odorless and a deadly gas. Always stand

behind snow thrower(operator's position)

when starting engine. Do not put hands,
feet, hair or loose clothing in or near the
discharge chute deflector or auger housing
while the engine is running. The tempera-
ture of the muffler and neaby areas may

exceed 150_F.; avoid these areas also.

Z_ WARNING: Objects such as gravel,

rocks or other debris, if struck by the auger,
may be thrown with sufficient force to cause
personal injury or property damager

We recommend standard safety glasses or
Wide Vision Safety Mask for over your
glasses.

SNow THROWING TIPS
, This snow thrower will propel itself

forward 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.
tf it does not, refer to Adjust Auger
Control Cable paragraph on page 11.

• 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.

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.

• 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.

, 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 cleating 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 will
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 1o
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.
The greater the depth, the slower you
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 jobs into the snow.
These short back and forth, 4 to 6 inch,

jabbing motions will "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 wil! be

required to remove snow of this type than
level snow.
