in cold weather. To prevent possible
freeze-up of recoil starter and engine
controls, proceed as follows after each
snow removal job.
1. With engine off, allow engine to cool
for several minutes.
2. Pull starter rope very slowly until re
sistance is felt, then stop. Allow the
starter rope to recoil. Repeat three
times.
3. With the engine not running, wipe all
snow and moisture from the carbu
retor cover in area of controls and
levers. Also, move the choke control
and starter handle several times.
WARNING; Never run en
gine indoors or in enclosed,
A
gine exhaust contains CARBON
MONOXIDE, AN ODORLESS AND
DEADLY GAS. Keep hands, feet,
hair and ioose clothing away from
any moving parts on engine and
snow thrower.
• Engine parts, especiaily the muf
fler, become extremely hot. Se
vere thermal burns can occur on
contact. Allow the engine to cool
before touching.
• Never allow children to operate
the snow thrower. Never allow
adults to operate the snow throw
er without proper instruction.
• Keep the area of operation ciear
of ail persons, particularly small
children and pets.
• Never leave the snowthrower un
attended while the engine is run
ning. Anyone operating the en
gine or equipment must carefuily
poorly ventilated areas. En
read and understand the operat

OPERATION
TO REMOVE SNOW FROM AUGER
WARNING: Do not attempt
to remove snow or debris
A
auger with your hands. Use the
cleaning stick to remove snow or
debris.
A cleaning stick is attached to the top of
the auger housing. Use the cleaning
that may become lodged in
SNOW THROWING TIPS
1. For maximum snow thrower efficien
cy in removing snow, adjust ground
speed. Go slower in deep, freezing
or wet snow. If the wheels slips, re
duce forward speed.
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 hardpacked snow surfaces, adjust the
skids upward so that the scraper
bar touches the ground.
6. On gravel or crushed rock surfaces,
stick to remove snow from the auger
housing.
• Release auger drive lever.
• Remove (do not turn) safety key.
• Disconnect spark plug wire.
• Do not place your hands in the au
ger or discharge chute. Use the
cleaning stick to remove snow.
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.
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.

GENERAL RECOMMENDATIONS
The warranty on this snow thrower does
not cover items that have been subjected
to operator abuse or negligence. To re
ceive tuli vaiue from the warranty, frie op
erator must maintain the snow thrower as
instructed in this manuai.
Some adjustments wiil need to be made
periodically to properly maintain your
snow thrower.
Maintenance, replacement, or repair of the
emission controi devices and systems can
be performed by any non-road engine re
pair estefoli^ment or individual. Regular
maintenance will improve the performance
and extend the life of the engine.
WARNING: Do not strike the
flywheel with a hammer or a
A
hard opject. If done, the fly
wheel can shatter during operation.
Do not tamper with the governor
spring, links or other parts to in
crease engine speed.
1
AFTER EACH USE
• Run the machine to clear the auger
of snow.
• To prevent freezing of the auger or
controls, remove all snow and slush
from the snow thrower.
• Check for any loose or damaged
parts.
• Tighten any loose fasteners.
• Check and maintain the auger.
• Check controls to make sure they
are fonctioning properly.
• If any parts are worn or damaged,
replace immediately.

POWER RATINGS
The power ratings for an individual
engine model are initially developed by
starting with SAE (Society of Automo
tive Engineers) code J1940 (Small
Engine Power & Torque Rating Proce
dure) (Revision 2002-05). Given both
the wide array of products on which our
engines are placed, and the variety of
environmental issues applicable to
operating the equipment, it may be that
the engine you have purchased will not
develop the rated horsepower when
used in a piece of power equipment
(actual “on-site” power). This difference
is due to a variety of factors including,
but not limited to, the following: differ
ences in altitude, temperature, baro
metric pressure, humidity, fuel, engine
lubrication, maximum governed engine
speed, individual engine to engine
variability, design of the particular piece
of power equipment, the manner in
which the engine is operated, engine
run-in to reduce friction and clean out of
combustion chambers, adjustments to
the valves and carburetor, and other
factors. The power ratings may also be
adjusted based on comparisons to
other similar engines utilized in similar
applications, and will therefore not
necessarily match the values derived
using the foregoing codes.
