RULES FOR SAFE OPERATION

IMPORTANT

WARNING: Always disconnect the spark plug wire and place it where it cannot make contact with
spark plug to prevent accidental starting during: Preparation, Maintenance, or Storage of your
snowthrower.

Safe Operation Practices for Snowthrowers

As Recommended By: American National Standards Institute.

Engine Exhaust, some of its constituents, and
certain vehicle components contain or emit
chemicals known to the State of California to
cause cancer and birth defects or other repro­ductive harm.

Battery posts, terminals and related accesso­ries contain lead and lead compounds, chemi­cals known to the State of California to cause
cancer and birth defects or other reproductive
harm. WASH HANDS AFTER HANDLING.

IMPORTANT: Safety standards require operator presence

controls to minimize the risk of injury. Your snowthrower is
equipped with such controls. Do not attempt to defeat the
function of the operator presence control under any cir­cumstances.

Training

1. Read the operating and service instruction manual care­fully. Be thoroughly familiar with the controls and the
proper use of the equipment. Know how to stop the unit
and disengage the controls quickly.

2. Never allow children to operate the equipment. Never
allow adults to operate the equipment without proper
instruction.

3. Keep the area of operation clear of all persons, particu­larly small children and pets.

4. Exercise caution to avoid slipping or falling especially
when operating in reverse.

Preparation

1. Thoroughly inspect the area where the equipment is to
be used and remove all doormats, sleds, boards, wires,
and other foreign objects.

2. Disengage all clutches before starting the engine
(motor).

3. Do not operate the equipment without wearing adequate
winter outer garments. Wear footwear that will improve
footing on slippery surfaces.

4. Handle fuel with care; it is highly flammable.

MTF-031072L

a. Use an approved fuel container.
b. Never remove fuel tank cap or add fuel to a running en-

gine (motor) or hot engine (motor).

c. Fill fuel tank outdoors with extreme care. Never fill fuel

tank indoors.
d. Replace fuel cap securely and wipe up spilled fuel.
e. Never store fuel or snowthrower with fuel in the tank

inside of a building where fumes may reach an open

flame or spark.
f. Check fuel supply before each use, allowing space for

expansion as the heat of the engine (motor) and/or sun

can cause fuel to expand.

5. For all units with electric starting motors use electric
starting extension cords certified CSA/UL. Use only with
a receptacle that has been installed in accordance with
local inspection authorities.

6. Adjust the snowthrower height to clear gravel or crushed
rock surface.

7. Never attempt to make any adjustments while the en­gine (motor) is running (except when specifically recom­mended by manufacturer).

8. Let engine (motor) and snowthrower adjust to outdoor
temperatures before starting to clear snow.

9. Always wear safety glasses or eye shields during oper­ation or while performing an adjustment or repair to pro­tect eyes from foreign objects that may be thrown from
the snowthrower.

OPERATION

OPERATING TIPS

1. For optimum snowthrower efficiency, adjust ground
speed, not the throttle. REMEMBER - if the wheels slip,
forward speed will be reduced. The engine is designed
to deliver optimum performance at full throttle and must
be run at this power setting at all times.

2. Most efficient snowblowing is accomplished when snow
is removed immediately after it falls.

3. For complete snow removal, slightly overlap each swath
previously taken.

4. Snow should be discharged downwind whenever pos­sible.

5. For normal usage, set the skids one-eighth inch (3 mm)
below the scraper bar . For extremely hard-packed snow
surfaces, the skids may be adjusted upward to insure
cleaning efficiency.

6. On gravel or crushed rock surfaces, the skids should be
set at 1-1/4 inch (32 mm) below the scraper bar (see To
Adjust Skid Height, in the MAINTENANCE section in this
manual). Rocks and gravel must not be picked up and
thrown by the machine.

7. After the snowblowing job has been completed, allow the
engine to idle for a few minutes, to melt snow and ice ac­cumulated on the engine.

8. Remove ice and snow accumulation from the entire
snowthrower to prevent obstructions and possible dam­age when snowthrower is subsequently operated.

9. Before starting snowthrower, always inspect augers and
impeller for ice accumulation and/or debris, which could
result in snowthrower damage.

10. Check oil level before every start. fill to “SAFE” indication
prior to operating snowthrower.

To help avoid possible freeze-up of starter, proceed as
follows:

Recoil Starter:

With engine running, pull starter rope with a rapid continuous
full arm stroke three (3) or four (4) times.

NOTE: The unusual sound made by pulling starter rope
will not harm the engine or the starter.

Electric Starter:

1. Connect the “POWER CORD” to the “SWITCH BOX” and
then to a 120 volt AC receptacle.

2. With engine running, push the “STARTER BUTTON”
and spin the starter for several seconds.

NOTE: The unusual sound made by spinning the
starter rope will not harm the engine or the starter.

3. Disconnect the “POWER CORD” from the receptacle
first and then from the “SWITCH BOX”.

MAINTENANCE

WARNING: Always turn unit off, remove igni­tion key and disconnect the spark plug wire be­fore making any repairs or adjustments.

AUGER HOUSING HEIGHT ADJUSTMENT
TO ADJUST SCRAPER BAR

After considerable use, the metal scraper bar will have a
definite wear pattern. The scraper bar in conjunction with the
skids should always be adjusted to allow one-eighth of an
inch (3 mm) between the scraper bar and the sidewalk or
area to be cleaned.

To adjust the scraper bar, proceed as follows:

1. Position the snowthrower on a level surface.

2. Loosen the carriage bolts and nuts securing the scraper
bar to the auger housing.

3. Adjust the scraper bar to the proper position. Tighten the
carriage bolts and nuts, insuring that the scraper bar is
parallel with the working surface.

4. For extended operation, the scraper bar may be re­versed. If the scraper bar must be replaced because of
wear, remove the carriage bolts and nuts and install a
new scraper bar.

TO ADJUST SKID HEIGHT

This snowthrower is equipped with two height adjust skids,
secured to the outside of the auger housing. These elevate
the front of the snowthrower.

When removing snow from a hard surface area such as a
paved driveway or walk, adjust the skids up to bring the front
of the snowthrower down.

When removing snow from rock or uneven construction,
raise the front of the snowthrower by moving the skids down.
This will help to prevent rocks and other debris from being
picked up and thrown by the augers.

To adjust skids, proceed as follows:

1. Place a block (equal to height from ground desired) un­der scraper bar near but not under skid.

2. Loosen skid mounting nuts (Figure 25) and push the skid
down until it touches the ground. Retighten mounting
nuts.

3. Set skid on other side at same height.

NOTE: Make sure that snowthrower is set at same height
on both sides.

WARNING: Be certain to maintain proper
ground clearance for your particular area to be

cleared. Objects such as gravel, rocks or other
debris, if struck by the impeller, may be thrown with
sufficient force to cause personal injury, property dam­age or damage to the snowthrower.

MAINTENANCE

AUGER SHEAR BOLT REPLACEMENT

The augers are secured to the auger shaft with special bolts
that are designed to break if an object becomes lodged in the
auger housing. Use of a harder bolt will reduce the protection
provided by the shear bolt. To replace a broken shear bolt,
proceed as follows:

WARNING: To insure safety and performance
levels, only original replacement shear bolts
should be used.

1. Move throttle to STOP, disengage all controls, discon­nect the spark plug lead wire, and insure all moving parts
have stopped.

Shear Pin

Spacer

2. Align the hole in the auger with the hole in the auger shaft.
Install new shear bolt, spacer and locknut found in the
toolbox located on the belt cover (See Figure 45).

NOTE: The spacer fits into the larger hole in the auger
tube.

TO ADJUST OR REPLACE THE SPARK PLUG

Check the spark plug every twenty-five (25) hours. Re-
place the spark plug if the electrodes are pitted or burned
or if the porcelain is cracked.

1. Clean spark plug and reset gap periodically.

2. Clean area around spark plug base before removal, to
prevent dirt from entering engine.

3. Replace spark plug if electrodes are pitted or burned or
if porcelain is cracked.

Locknut

STORAGE

OFF SEASON STORAGE

WARNING: Never store the engine, with fuel i n
the tank, indoors or in a poor ventilated enclo-

sure where fuel fumes could reach an open
flame, spark or pilot light as on a furnace, water heater ,
clothes dryer, etc.
Handle gasoline carefully. It is highly flammable and
careless use could result In serious fire damage to your
person and /or property.
Drain fuel into approved containers outdoors, away
from open flame.

If the snowthrower is to be stored for thirty (30) days or more
at the end of the snow season, the following steps are
recommended to prepare your snowthrower for storage.

NOTE: Gasoline must be removed or treated to prevent
gum deposits from forming in the tank, filter, hose, and
carburetor during storage.

1. To remove gasoline, run engine until tank is empty and
engine stops.

If you do not want to remove the gasoline, add fuel stabilizer
to any gasoline left in the tank to minimize gum deposits and
acids. If the tank is almost empty, mix stabilizer with fresh
gasoline in a separate container and add some to the tank.
ALWAYS FOLLOW INSTRUCTIONS ON STABILIZER
CONTAINER. THEN RUN ENGINE AT LEAST 10 MINUTES
AFTER STABILIZER IS ADDED TO ALLOW MIXTURE TO
REACH CARBURETOR. STORE SNOWTHROWER IN
SAFE PLACE.

2. You can help keep your engine (4-cycles only) in good
operating condition by changing oil before storage.

3. Lubricating the piston/cylinder area. This can be done by
first removing the spark plug and squirting clean engine
oil into the spark plug hole. Then cover the spark plug
hole with a rag to absorb oil spray. Next, rotate the engine
by pulling the starter two or three times. Finally, reinstall
spark plug and attach spark plug wire.

4. Thoroughly clean the snowthrower.

5. Lubricate all lubrication points (see “Lubrication“ in the
Maintenance section).

6. Insure that all nuts, bolts, and screws are securely fas­tened. Inspect all visible moving parts for damage,
breakage, and wear. Replace if necessary.

7. Touch up all rusted or chipped paint surfaces; sand lightly
before painting.

8. Cover the bare metal parts of the snowthrower housing
auger, and the impeller with rust preventative.

9. If possible, store your snowthrower indoors and cover it
to give protection from dust and dirt.

10. On models with folding handles, loosen the knobs that
secure the upper handle. Rotate the upper handle back.

11. If the machine must be stored outdoors, block up the s­nowthrower and insure the entire machine is off the
ground. Cover the snowthrower with a heavy tarpaulin.

REMOVING THE SNOWTHROWER FROM
STORAGE

When removing the snowthrower from storage, follow the
steps below.

1. Put the upper handle in the operating position, tighten the
knobs that secure the upper handle.

2. Fill the fuel tank with a fresh fuel.

3. Check the spark plug. Make sure the gap is correct. If the
spark plug is worn or damaged, replace before using.

4. Make sure all fasteners are tight.

5. Make sure all guards, shields, and covers are in place.

6. Make sure all adjustments are correct.
