vapors are explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
a. Use only an approved gasoline container.
b. Extinguish all cigarettes, cigars, pipes and other
sources of ignition.
c. Never fuel machine indoors.
d. Never remove gas cap or add fuel while the engine is
hot or running.
e. Allow engine to cool at least two minutes before
refueling.
f. Never over fill fuel tank. Fill tank to no more than ½
inch below bottom of filler neck to provide space for
fuel expansion.
g. Replace gasoline cap and tighten securely.
h. If gasoline is spilled, wipe it off the engine and
equipment. Move machine to another area. Wait 5
minutes before starting the engine.
i. Never store the machine or fuel container inside

(e.g. furnace, water heater, space heater, clothes
dryer etc.).
j. Allow machine to cool at least 5 minutes before
storing.
k. Never fill containers inside a vehicle or on a truck
or trailer bed with a plastic liner. Always place
containers on the ground away from your vehicle
before filling.
l. If possible, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. If this
is not possible, then refuel such equipment on a
trailer with a portable container, rather than from a
gasoline dispenser nozzle.
m. Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.
Operation
1. Do not put hands or feet near rotating parts, in the auger/
impeller housing or chute assembly. Contact with the
rotating parts can amputate hands and feet.
2. The auger/impeller control lever is a safety device. Never
bypass its operation. Doing so makes the machine unsafe
and may cause personal injury.
3. The control levers must operate easily in both directions
and automatically return to the disengaged position when
released.
4. Never operate with a missing or damaged chute assembly.
Keep all safety devices in place and working.
5. Never run an engine indoors or in a poorly ventilated area.
Engine exhaust contains carbon monoxide, an odorless
and deadly gas.
6. Do not operate machine while under the influence of
alcohol or drugs.
7. Muffler and engine become hot and can cause a burn. Do
not touch. Keep children away.
8. Exercise extreme caution when operating on or crossing
gravel surfaces. Stay alert for hidden hazards or traffic.
9. Exercise caution when changing direction and while
operating on slopes. Do not operate on steep slopes.
10. Plan your snow-throwing pattern to avoid discharge
towards windows, walls, cars etc. Thus, avoiding possible
property damage or personal injury caused by a ricochet.
11. Never direct discharge at children, bystanders and pets or
allow anyone in front of the machine.
12. Do not overload machine capacity by attempting to clear
snow at too fast of a rate.

handles. Walk, never run.
14. Disengage power to the auger/impeller when transporting
or not in use.
15. Never operate machine at high transport speeds on
slippery surfaces. Look down and behind and use care
when backing up.
16. If the machine should start to vibrate abnormally, stop
the engine, disconnect the spark plug wire and ground it
against the engine. Inspect thoroughly for damage. Repair
any damage before starting and operating.
17. Disengage all control levers and stop engine before you
leave the operating position (behind the handles). Wait
until the auger/impeller comes to a complete stop before
unclogging the chute assembly, making any adjustments,
or inspections.
18. Never put your hand in the discharge or collector openings.
Do not unclog chute assembly while engine is running.
Shut off engine and remain behind handles until all moving
parts have stopped before unclogging.
19. Use only attachments and accessories approved by the
manufacturer (e.g. wheel weights, tire chains, cabs etc.).
20. When starting engine, pull cord slowly until resistance
is felt, then pull rapidly. Rapid retraction of starter cord
(kickback) will pull hand and arm toward engine faster than
you can let go. Broken bones, fractures, bruises or sprains
could result.
21. If situations occur which are not covered in this manual, use
care and good judgment. Contact Customer Support for
assistance and the name of your nearest servicing dealer.

manual are applicable to all snow thrower models and the snow
thrower depicted may differ from yours.
Engine Controls
See the Engine Operator’s Manual for the location and function
of the controls on the engine.
Auger
When engaged, the auger rotation draws snow into the auger
housing and throws it out the discharge chute. Rubber paddles
on the auger also aid in propelling the snow thrower as they
come in contact with the pavement.
Auger Control
Located on the upper handle, the auger control is used to
engage and disengage drive to the auger. Squeeze the control
against the upper handle to engage the auger; release it to
disengage.
Chute Assembly
Rotate the discharge chute to the left or right using the chute
handle. The pitch of the discharge chute controls the angle at
which the snow is thrown. Loosen the wing knob on the side of
the discharge chute before pivoting the discharge chute upward
or downward. Retighten the knob once the desired position has
been achieved.
Shave Plate
The shave plate maintains contact with the pavement as
the snow thrower is propelled, allowing snow close to the
pavement’s surface to be discharged.
Recoil Starter Handle
The recoil starter handle is used to manually start the engine.

Operation 5
10
NOTE: Refer to the Engine Operator’s Manual for instruction on
starting, stopping and operating the engine.
Engaging the Auger
1. To engage the auger and start throwing snow, squeeze the
auger control against the handle. Release to stop the auger.
See Fig. 5-1.
Engaging the Drive
Lift up slightly on the handle to allow the rubber paddles on the
auger to contact the pavement and propel the snow thrower
forward. Pushing downward on the handle will raise the auger
off the ground and stop the forward motion.
NOTE: Excessive upward pressure on the handle will result
in premature wear on the rubber auger blades which will
not be covered by the warranty.
Clearing a Clogged Discharge Chute
WARNING! Never use your hands to clear a
clogged chute assembly. Shut off engine and remain
behind handles until all moving parts have stopped
before using a clean-out tool to clear the chute
assembly.
Hand contact with the rotating impeller inside the discharge
chute is the most common cause of injury associated with snow
throwers. Never use your hand to clean out the discharge chute.
To clear the chute:
1. SHUT THE ENGINE OFF!
2. Wait 10 seconds to be sure the impeller blades have
stopped rotating.
3. Always use a clean-out tool, not your hands.
Chute Assembly
The pitch of the chute assembly controls the angle at which the
snow is thrown.
1. Loosen the wing knob found on the left side of the chute
assembly and pivot the upper chute upward or downward
to the desired pitch. Retighten the wing knob before
operating the snow thrower.

Adjustments
WARNING! Before servicing, repairing or
inspecting the snow thrower, disengage the auger
control. Stop the engine and remove the key to
prevent unintended starting.
Shave Plate
To check the adjustment of the shave plate, place the machine
on a level surface. The wheels, shave plate and auger should all
contact the level surface. Note that if the shave plate is adjusted
too high, snow may blow under the housing. If the shave plate
wears out excessively, or the snow thrower does not self-propel,
the shave plate may be too low and needs to be adjusted.
NOTE: On new snow throwers or machines with a new shave
plate installed, the auger may be slightly off the ground.
To adjust the shave plate proceed as follows:
1. Drain the gas from the snow thrower by running the
engine until it is empty.
2. Pull the recoil starter handle until resistance is felt. Then tip
the snow thrower back until it rests on the handles.
3. Loosen the four flange lock nuts and carriage bolts which
secure the shave plate to the housing. See Fig. 6-1. Move
the shave plate to the desired position and retighten the
nuts and bolts securely.
4. Tip the snow thrower back to the operating position and pull
the starter handle a few times to see if it is difficult to pull.
5. If the starter is difficult to pull, remove the spark plug and
pull the handle several times to ensure that any oil trapped
in the head is removed.
CAUTION: Oil may come out of the spark plug
hole when it is removed and the starter handle is
pulled.
6. Inspect the spark plug. If it is wet, clean off any oil before
re-installing.
Control Cable
As a result of both the control cable and the auger drive belt
stretching due to wear, periodic adjustments may be necessary.
If the auger seems to hesitate when rotating, proceed as follows:
The upper hole in the control handle provides for an adjustment
in cable tension. To adjust, disconnect the end of control cable
from the bottom hole in the control handle and reinsert it in the
upper hole. Insert the cable from the outside as shown in Fig. 6-2.

commencing on the date of original purchase and will, at its option, repair or replace, free of charge, any part found to be defective in materials or workmanship.
This limited warranty shall only apply if this product has been operated and maintained in accordance with the Operator’s Manual furnished with the product, and
has not been subject to misuse, abuse, commercial use, neglect, accident, improper maintenance, alteration, vandalism, theft, fire, water, or damage because
of other peril or natural disaster. Damage resulting from the installation or use of any part, accessory or attachment not approved by MTD for use with the

parts include, but are not limited to items such as: batteries, belts, blades, blade adapters, grass bags, rider deck wheels, seats, snow thrower skid shoes,

purchaser (or the original person for whom this product was purchased as a gift). Control mechanisms attached to the Snow Chute, such as cables and control link-
ages, are covered under the other terms of this limited warranty, but are not covered by this paragraph (or beyond the normal applicable warranty period). Except
