designed for use when the tem-
perature is below 32 degrees.
BEFORE STARTING THE ENGINE
1. Before you service or start the en-
gine, familiarize yourself with the
snow thrower. Be sure you under-
stand the function and location of all
controls.
2. Check the tension of clutch cable
before starting the engine. See To
Adjust The Control Cable para-
graph in the Service & Adjust-
ments section of this manual.
3. Be sure that all fasteners are tight.
4. Make sure the height adjust skids
are properly adjusted. See To Ad-
just Skid Height paragraph in the
Service & Adjustments section of
this manual.
5. Checktire pressure (14-17
pounds). Do not exceed maximum
amount of pressure.
CHECK THE OIL:
NOTE: The engine was shipped from
the factory filled with oil. Check the lev-
el of the oil. Add oil as needed.
F-031068L
When the temperature falls below 32 de-
grees, use the heated grips to keep your
hands warm. Move the heated grip switch
to the ON position (see Figure 14). It will
take a couple of minutes for the grips to be-
come warm. Because heated grips can be-
come very warm, we recommend that you
wear gloves. If you notice that the grips are
too warm, turn off heated grips.
TO Add Oil
1. Make sure the unit is level.
NOTE: Do not check the level of the
oil while the engine runs.
2. Remove the oil fill cap/dipstick.
Check the oil.
3. If necessary, add oil untilthe oil
reaches the FULL mark on the oil fill
cap/dipstick (see Figure 16). Do not
add too much oil.
OII Fill Cap/Dipstick

FILL GAS:
The engine is certified to comply with
California and US EPA emission regula-
tions for ULGE (Utility or Lawn and Gar-
den Equipment) engines. ULGE
engines are certified to operate on reg-
ular unleaded gasoline.
_lb ARNING: 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 sys-
tem of an engine while in storage.
NOTE: To avoid engine problems, the
fuel system must be emptied before
storage for 30 days or longer. Start the
engine and let it run until the fuel lines
and carburetor are empty. Use fresh
fuel next season. See the Storage sec-
tion in this manual for additional infor-
mation.
Never use engine or carburetor cleaner
products in the fuel tank or permanent
damage may occur.
Fill the fuel tank only with a fresh,
clean, unleaded regular, unleaded pre-
mium, or reformulated automotive gas-
oline. DO NOT use leaded gasoline.
Make sure that the container you pour
the gasoline from is clean and free from
rust or other foreign particles. Never
use gasoline that may be stale from
long periods of storage in the container.
Fuel Tank
Figure 17
_lb ARNING: Gasoline is flam-
mable. Always use caution
when handling or storing
gasoline.
• Do not fill fuel tank while snow
thrower is running, when it is hot,
or when snow thrower is in an en-
closed area.
• Keep away from open flame or an
electrical spark and do not smoke
while filling the fuel tank.
• Never fill the tank completely. Fill
the tank to within 1/4"-1/2" from
the top to provide space for ex-
pansion of fuel.
• Always fill fuel tank outdoors and
use a funnel or spout to prevent
spilling.
• Make sure to wipe up any spilled
fuel before stating the engine.
• Store gasoline in a clean, ap-
proved container and keep the
cap in place on the container.

Figure 18
2. Pull out and remove the ON/OFF
key (see Figure 19). Keep the
ON/OFF key in a safe place. The
engine will not start without the
ON/OFF key.
_lb ARNING: The starter is
equipped with a three-wire
power cord and plug and is
designed to operate on 120 volt AC
household current. It must be prop-
erly grounded at all times to avoid
the possibility of electrical shock
which may be injurious to operator.
• Follow all instructions carefully
as set forth in the "To Start En-
gine" section.
• Determine that your house wiring
is a three-wire grounded system.
Ask a licensed electrician if you
are not sure. If your house wire
system is not a three-wire system,
do not use this electric starter un-
der any conditions.
• If your system is grounded and a
three-hole receptacle is not avail-
able at the point your starter will
normally be used, one should be
installed by a licensed electrician.
• When connecting 120 volt AC
"Power Cord", always connect the
cord to the Switch Box on the en-
gine first, then plug the other end
into the three-hole grounded re-
ceptacle. When disconnecting
"Power Cord", always unplug the
end in the three-hole grounded re-
ceptacle first.

SNOW THROWING TIPS
1. For maximum snow thrower efficien-
cy in removing snow, adjust ground
speed, NEVER the throttle. Go
slower in deep, freezing or wet
snow. If the wheels slips, reduce
forward speed. The engine is de-
signed to deliver maximum perfor-
mance at full throttle and should be
run at this power setting at all times.
2. Most efficient snow throwing is ac-
complished when the snow is re-
moved immediately after if falls.
3. For complete snow removal, slightly
overlap each path previously taken.
4. The snow should be discharged
down wind whenever possible.
5. For normal usage, set the skids so
that the scraper bar is 1/8" above
the skids. For extremely hard-
packed snow surfaces, adjust the
F-031068L

Move throttle lever to stop position.
Remove (do not turn) ignition key.
Disconnect spark plug wire.
Do not place your hands in the au-
ger or discharge chute. Use a pry

skids upward so that the scraper
bar touches the ground.
6. On gravel or crushed rock surfaces,
set the skids at 1-1/4" below the
scraper bar. See To Adjust Skid
Height paragraph in the Service &
Adjustments section of this manu-
al. Rocks and gravel must not be
picked up and thrown by the ma-
chine.
7. After the snow throwing job has
been completed, allow the engine to
idle for a few minutes, which will
melt snow and accumulated ice off
the engine.
8. Clean the snow thrower thoroughly
after each use.
9. Remove ice and snow accumulation
and all debris from the entire snow
thrower, and flush with water (if pos-
sible) to remove all salt or other
chemicals. Wipe snow thrower dry.
