of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment.
The triangle in text signifies important cautions or warnings which must be followed.
SLOPE OPERATION
Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death.
All slopes require extra caution. If you cannot back up the
slope or if you feel uneasy on it, do not operate on it.
Do
• See your authorized dealer for recommendations
counterweights to improve stability.
• Travel up and down slopes, not across.
• Remove obstacles such as rocks, tree limbs, etc.
• Watch for holes, ruts, or bumps. Uneven terrain could
overturn the unit. Snow can hide obstacles.
• Use slow speed. Tires may lose traction on slopes.
Choose a low gear so that you will not have to stop or
shift while on the slope.
• Keep all movement on the slopes slow and gradual.
Do not make sudden changes in speed or direction.
• Always keep unit in gear especially when traveling
downhill.
Do Not
• Do not start or stop on a slope. If tires lose traction,
disengage the auger and proceed slowly straight
down the slope.
• Do not turn on slopes unless necessary, and then,
turn slowly and gradually downhill, if possible.
• Do not operate near drop-offs, ditches, or embankments. The unit could suddenly turn over if a wheel is
over the edge of a cliff or ditch, or if an edge caves in.
• Do not operate on wet surfaces. Reduced traction
could cause sliding.
• Do not shift to neutral and coast down hills.
WARNING
Never operate on slopes greater than 17.6 percent (10°) which
is a rise of 3-1/2 feet (106 cm) vertically in 20 feet (607 cm)
horizontally.
When operating on slopes use additional wheel weights or
counterweights. See your dealer to determine which weights
are available and appropriate for your unit.
Select slow ground speed before driving onto slope. Travel
UP and DOWN the slope, never across the face, use caution
when changing directions and DO NOT START OR STOP ON
SLOPE.
• Data indicates that operators, age 60 years and
above, are involved in a large percentage of power
equipment-related injuries. These operators should
evaluate their ability to operate the unit safely enough
to protect themselves and others from injury.
• All operators should seek and obtain professional
and practical instruction.
• Always wear substantial footwear and appropriate
winter clothing. Wear foot-ware that improves traction on slippery slopes. DO NOT wear long scarves
or loose clothing that could become entangled in
moving parts.
• Before using, always visually check that all hardware
is present, in-tact, and secure. Replace worn or
damaged parts.
• Never operate the machine with defective guards, or
without safety protective devises in place.
• Stop engine before: refuelling, removing an attachment, making adjustments (unless the adjustment

• Gasoline and oil must be premixed in a clean fuel
container.
• Always use fresh, unleaded, winter grade fuel
• Never put plain, unmixed fuel into fuel tank. Shake
fuel container each time before filling fuel tank.
• Never use “stale” fuel left over from last season or
stored for long periods.
• DO NOT USE MULTI VISCOSITY OILS, SUCH AS
10W-30 or 10W-40.
WARNING
Gasoline is highly flammable and must be handled
with care. Never fill the tank when the engine is hot or
running. Always move outdoors to fill the tank. Keep
snowthrower and gasoline away from open flame or
spark.
PROPER FUEL MIXING PROCEDURE
1. Fill approved clean fuel container one quarter full with
fresh unleaded fuel - one quart (one liter) in a one
gallon (4 liter) container.
2. Pour recommended amount of high quality two
cycle oil — 2.5 ounces (80 ml) into fuel container for
one gallon (4 liters) of fuel. (NOTE: DO NOT USE
MULTI VISCOSITY OILS, SUCH AS 10W-30 or
10W-40.)
3. Reinstall cap on the fuel container and shake container vigorously so oil mixes with gasoline.

OPERATING THE SNOWTHROWER
Before operating snowthrower, review the
Checks Before
Each Use
under General Operation on page 8 of this
manual.
1. Rotate the discharge chute to the desired direction.
2. Pull the Auger Control back against the handle to
engage the auger.
NOTE: The snow thrower will be pulled forward by
the auger when the auger contacts the ground or with
the snow to be thrown.
3. Begin snow removal by clearing a path down the center of walk or driveway, then gradually widen path,
throwing snow off to both sides.
4. Release the Auger Control to stop both the auger
and the forward motion of the snowthrower.
SNOWTHROWING TIPS
Discharge chute icing may occur as the result of snow
build up around the base of the discharge chute. If the
chute does freeze up, DO NOT force the control: control
linkage damage may result. Put the unit indoors and
allow the ice to melt, or pour hot water around the inside
and outside base of the discharge chute.
Varying snow conditions will affect performance of
snow thrower. The snow thrower should be allowed to
move into the snow at it's own pace.
Wet, heavy snow — When clearing wet, heavy snow,
the forward movement of the snowthrower may have to
be slowed by pushing down on handle while allowing
engine to operate at full throttle.
Do not operate on gravel or crushed rock surfaces.
Avoid picking up this type of material with auger since
damage to unit could result and particles can be discharged with considerable force that could cause serious
injury.
Always be alert to hidden hazards that might be struck
by the auger. Should a foreign object be struck by the
auger, immediately stop the engine and inspect machine
for any damage. Repair damage before continuing operation.
Controls & Operation
WARNING
Do not use snow thrower on surfaces above ground
level, such as the roof of a building.
AFTER EACH USE
Allow snow thrower to run a few minutes after clearing
snow to reduce the likelihood of parts freezing while
machine is not is use.
If you will be storing the unit for the season, see the
STORAGE section for instructions on properly preparing
the unit for long-term storage.
OFF-SEASON STORAGE
Before you store your snowthrower for the off-season,
read the Maintenance and Storage instructions in the
Safety Rules section and take the following precautions:
NOTE: Gasoline, if permitted to stand unused for extended periods (30 days or longer), may develop gummy
deposits which can adversely affect the engine carburetor and cause engine malfunction. To avoid this condition, add Simplicity Gasoline Stabilizer to the fuel tank, or
drain all fuel from the system before placing unit in storage.
1. Prepare your snowthrower engine for storage as
instructed in the Engine Owner’s Manual.
2. Lubricate the snowthrower as described in the
LUBRICATION section of this manual.
3. Clean the snowthrower thoroughly. Coat exposed
bare metal parts with a quality paint (available from
you dealer) or a light film of grease, oil or automotive
wax.
4. Store snowthrower in the wheels down, operating
position.
Note: If the unit is stored in any other posi-
tion, fluids may leak.
5. Store the unit in a protected area and cover.
STARTING AFTER STORAGE
1. Remove the spark plug and wipe dry. Then reinstall
plug.
2. Fill fuel tank with fresh gasoline (unless a fuel stabilizer was used).
3. Check to be sure engine fins are clean and air flow is
unobstructed.
4. Start the engine outdoors. Warm up engine by running at SLOW speed for a a few minutes before running at FAST speed, or blowing snow.
5. Check the operation of all the controls. If necessary,
lubricate the snowthrower to improve operation of the
chute control.

LUBRICATION
Note: The drive pulley end of auger shaft is supported by
a sealed ball bearing and requires no lubrication. The
ball bearing on other end of auger shaft is also sealed,
and will not require lubrication.
Lightly Oil
• A few drops of oil should be placed on wheel
hubs occasionally to keep wheels turning
freely.
• Apply oil to pivot points of auger control periodically, wiping off any excess oil.
• A couple of drops of light machine oil applied to
upper end of auger control cable will assure free
movement of cable through outside casing. Wipe off
any excess oil.
• Remove belt cover and lightly apply oil to the pivot
point for idler pulley arm. BE CAREFUL NOT TO
GET OIL ON BELT OR PULLEYS.
Grease
• At the beginning of each snow throwing season, remove discharge chute and generously
lubricate steel flange at back of rotating ring
with light grease. Rotate ring with crank to distribute grease.
Engine Lubrication
The two cycle engine used in this snow thrower is lubricated by the fuel and oil mixture. Observe recommended
fuel to oil mixture ratio shown on page 9.

Troubleshooting & Service
Adjusting the Cable
1. Remove the engine cover.
2. Locate and loosen the lower locknut securing the
auger control cable (shown in Figure 14).
3. To change the slack in the cable, turn the upper locknut slightly just until the slack between the spring
and the exposed cable has been eliminated.
4. Tighten the lower locknut.
5. Test the units to make certain that the cable has
been adjusted properly.
Testing the Auger Control Cable
Start the snow thrower engine and pull back on auger
control to operate auger. Release auger control and
check to be sure auger stops turning.
If auger continues to turn after auger control is
released, cable is too tight and will have to be adjusted to make it longer. Cable must be slightly slack
when auger control is released (away from handle).
CARBURETOR ADJUSTMENT
The carburetor is properly calibrated and preset at the
factory for efficient cold weather operation. There are no
adjusting screws on the carburetor.
If it is apparent that the carburetor is not providing satisfactory fuel supply to engine, contact your nearest
Authorized Tecumseh Service Outlet for service.
AUGER CONTROL
CABLE ADJUSTMENT
The length of the auger control cable is adjustable.
However, it will seldom be necessary to change the
cable length since the operating tension on the drive belt
is maintained by the spring on the end of the cable.
If the auger turns too slowly under heavy load or
momentary squealing of drive belt is heard when entering heavy snow, pressure applied to drive belt by idler
pulley must be increased by reducing the slack in the
cable.
If the auger continues to turn when the auger control
is released, the cable is too tight. The pressure applied
to the drive belt must be eliminated by increasing the
amount of slack to the cable adjustment.
WARNING
Use extreme care when making adjustments that
require engine to be running. Keep hands, feet, hair
and loose clothing away from any moving parts.
Figure 14. Auger Control Cable
Locknuts
Spring
WARNING
Make certain the cable is NOT placing any tension on
the spring.
If the cable places tension on the spring,
the auger may turn when the control has not been
engaged.
Checking the Adjustment.
1. Remove the Cover. (See page 13.)
2. Measure the spring while the auger control on the
handle is disengaged. Record this measurement.
3. Pull the auger control against the handle and again
measure the spring. Record this measurement.
4. Compare the two measurements. The measurement
obtained with the spring extended should be 7/16
inch (11 mm) greater than with the spring at rest.
