IMPORTANT
Safe Operation Practices for Walk-Behind Snow Throwers
This snow thrower is capable of amputating hands and feet and throwing objects.
Failure to observe the following safety instructions could result in serious injury.
WARNING: Snow throwers have exposed rotating parts, which can cause
severe injury from contact, or from material thrown from the discharge chute.
Keep the area of operation clear of all
persons, small children and pets at all
times including startup.
Look for this symbol to point out important safety precautions. It means
CAUTION!!! BECOME ALERT!!! YOUR
SAFETY IS INVOLVED.
WARNING: Always disconnect spark
plug wire and place it where it cannot
contact plug in order to prevent accidental starting when setting up, transporting, adjusting or making repairs.
CAUTION: Muffler and other engine
parts become extremely hot during
operation and remain hot after engine
has stopped. To avoid severe burns on
contact, stay away from these areas.
WARNING: This snow thrower is for
use on sidewalks, driveways and other
ground level surfaces. Caution should
be exercised while using on sloping
surfaces. Do not use snow thrower on
surfaces above ground level such as
roofs of residences, garages, porches
or other such structures or buildings.
WARNING: 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.

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 and shift into neutral before
starting the engine (motor).
3. Do not operate the equipment without wearing adequate
winter garments. Avoid loose fitting clothing that can
get caught in moving parts. Wear footwear that will
improve footing on slippery surfaces.
4. Handle fuel with care; it is highly flammable
(a) Use an approved fuel container.
(b) Never add fuel to a running engine or hot engine.
(c) Fill fuel tank outdoors with extreme care. Never fill
fuel tank indoors.
(d) 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.
(e) When practical, 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.
8.
9.
(f) Keep the nozzle in contact with the rim of the fuel
tank or container opening at all times, until refueling
is complete. Do not use a nozzle lock-open device.
(g) Replace gasoline cap securely and wipe up spilled
fuel.
(h) If fuel is spilled on clothing, change clothing immediately.
Use extension cords and receptacles as specified by
the manufacturer for all units with electric drive motors
or electric starting motors.
Adjust the collector housing height to clear gravel or
crushed rock surface.
Never attempt to make any adjustments while the
engine (motor) is running (except when specifically
recommended by manufacturer).
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 machine.
Use ear protectors to avoid damage to hearing.
Operation
1. Do not put hands or feet near or under rotating parts.
Keep clear of the discharge opening at all times.
2. Exercise extreme caution when operating on or crossing gravel drives, walks, or roads. Stay alert for hidden
hazards or traffic.
3. After striking a foreign object, stop the engine (motor),
remove the wire from the spark plug, disconnect the
cord on electric motors, thoroughly inspect the snow
thrower for any damage, and repair the damage before
restarting and operating the snow thrower.
4. If the unit should start to vibrate abnormally, stop the
engine (motor) and check immediately for the cause.
Vibration is generally a warning of trouble.
5. Stop the engine (motor) whenever you leave the operating position, before unclogging the collector/impeller
housing or discharge chute, and when making any
repairs, adjustments or inspections.
2
6. When cleaning, repairing or inspecting the snow
thrower, stop the engine and make certain the collector/
impeller and all moving parts have stopped. Disconnect
the spark plug wire and keep the wire away from the
plug to prevent someone from accidentally starting the
engine.
7. Do not run the engine indoors, except when starting
the engine and for transporting the snow thrower in or
out of the building. Open the outside doors; exhaust
fumes are dangerous.
8. Exercise extreme caution when operating on slopes.
9. Never operate the snow thrower without proper guards,
and other safety protective devices in place and working.
10. Never direct the discharge toward people or areas
where property damage can occur. Keep children and
others away.
11. Do not overload the machine capacity by attempting
to clear snow at too fast a rate.
12. Never operate the machine at high transport speeds
on slippery surfaces. Look behind and use care when
operating in reverse.
13. Disengage power to the collector/impeller when snow
thrower is transported or not in use.
14. Use only attachments and accessories approved by
the manufacturer of the snow thrower (such as wheel
weights, counterweights, or cabs).

FIG. 15
USING THE CLEAN-OUT TOOL (See Fig. 16)
In certain snow conditions, the discharge chute may become clogged with ice and snow. Use the clean-out tool
to dislodge this blockage.
•
Slower speeds are for heavier snow and faster speeds
are for light snow and transporting the snow thrower.
It is recommended that you use a slower speed until
you are familiar with the operation of the snow thrower.
NOTE: When both traction drive and auger control levers
are engaged, the traction drive control lever will lock the
auger control lever in the engaged position. This will allow
you to release your right hand from the handle and adjust
the discharge chute direction without interrupting the snow
throwing process.
When cleaning, repairing, or inspecting, make
certain all controls are disengaged and the auger/impeller and all moving parts have stopped.
Disconnect the spark plug wire and keep the
wire away from the spark plug to prevent accidental starting.
•
•
Release the auger control lever and shut off the engine.
Remove the clean-out tool from it's mounting clip. Grasp
the tool firmly by the handle and push and twist the tool
into the discharge chute to dislodge the blockage.
After the packed snow has been dislodged, return the cleanout tool to it's mounting clip by pushing it into the clip.
• Make sure the discharge chute is pointed in a safe direction (no vehicles, buildings, people, or other objects are
in the direction of discharge) before restarting engine.

TO ADJUST SKID PLATES (See Fig. 19)
NOTE: The wrench provided in your parts bag may be
used to adjust the skid plates.
Skid plates are located on each side of the auger housing
and adjust the clearance between the scraper bar and the
ground surface. Adjust skid plates evenly to proper height
for current surface conditions. For removal of snow in
normal conditions, such as a paved driveway or sidewalk,
place skid plates in the highest position (lowest scraper
clearance) to give a 1/8" clearance between the scraper
bar and the ground. Use a middle position if the surface
to be cleared is uneven.
NOTE: It is not recommended to operate the snow thrower
over gravel or rocky surfaces. Objects such as gravel, rocks
or other debris, can easily be picked up and thrown by the
impeller, which can cause serious personal injury, property
damage or damage to the snow thrower.
• If snow thrower must be operated over gravel surface,
use extra caution and be sure skid plates are adjusted
to lowest (highest scraper clearance) position.
1. Shut off engine and wait for all moving parts to stop.
2. Adjust skid plates by loosening the hex nuts, then moving skid plate to desired position. Be sure both plates
are adjusted evenly. Tighten securely.

7. When the engine starts, release the recoil starter handle
and slowly move the choke control to the “OFF” position.
Allow the engine to warm up for a few minutes. Engine will
not develop full power until it has reached normal operating
temperature.
WARM START - RECOIL STARTER
Follow the steps above, keeping the choke in the “OFF”
position. DO NOT push the primer.
CAUTION: Alcohol blended fuels (called gasohol or using ethanol or methanol) can attract
moisture which leads to separation and formation of acids during storage. Acidic gas can
damage the fuel system of an engine while in
storage. To avoid engine problems, the fuel
system should be emptied before storage of
30 days or longer. Empty the gas tank, start
the engine and let it run until the fuel lines
and carburetor are empty. Use fresh fuel next
season. See Storage Instructions for additional
information. Never use engine or carburetor
cleaner products in the fuel tank or permanent
damage may occur.

TO START ENGINE
• Ensure fuel shut-off valve is in the “OPEN” position.
Your snow thrower engine is equipped with both a 120 Volt
A.C. electric starter and a recoil starter. The electric starter
is equipped with a three-wire power plug and is designed
to operate on 120 Volt A.C. household current.
• Ensure your house is a 120 Volt A.C. three-wire
grounded system. If you are uncertain, consult a
licensed electrician.
NOTE: Use an extension cord recommended for outdoor
use that is not longer than 50 feet (15 m).
WARNING: Do not use the electric
starter if your house is not a 120 Volt A.C.
three-wire grounded system. Serious
personal injury or damage to your snow
thrower could result.
BEFORE STOPPING
Run the engine for a few minutes to help dry off any moisture
on the engine.

OPERATION
IF RECOIL STARTER HAS FROZEN
If the recoil starter has frozen and will not turn the engine,
proceed as follows:
1. Grasp the recoil starter handle and slowly pull as much
rope out of the starter as possible.
2. Release the recoil starter handle and let it snap back
against the starter.
If the engine still fails to start, repeat the above steps or
use the electric starter.
SNOW THROWING TIPS
•
•
•
•
•
•
•
•
•
•
•
Always operate the snow thrower with the engine at
full throttle. Full throttle offers the best performance.
Go slower in deep, freezing or heavy wet snow. Use the
drive speed control, NOT the throttle, to adjust speed.
It is easier and more efficient to remove snow immediately after it falls.
The best time to remove snow is the early morning.
At this time the snow is usually dry and has not been
exposed to the direct sun and warming temperatures.
Slightly overlap each successive path to ensure all
snow will be removed.
Throw snow downwind whenever possible.
Adjust the skid plates to proper height for current snow
conditions. See “TO ADJUST SKID PLATES” in this
section of this manual.
For extremely heavy snow, reduce the width of snow
removal by overlapping previous path and moving
slowly.
Keep engine clean and clear of snow during use. This
will help air flow and extend engine life.
After snow-throwing is completed, allow engine to run
for a few minutes to melt snow and ice off the engine.
Clean the entire snow thrower thoroughly after each
use and wipe dry so it is ready for next use.
WARNING: Do not operate snow
thrower if weather conditions impair
visibility. Throwing snow during a
heavy, windy snowstorm can blind
you and be hazardous to the safe
operation of the snow thrower.

The warranty on this snow thrower does not cover items
that have been subjected to operator abuse or negligence.
To receive full value from the warranty, operator must
maintain snow thrower as instructed in this manual. Some
adjustments will need to be made periodically to properly
maintain your snow thrower.
At least once a season, check to see if you should make
any of the adjustments described in the Service and Adjustments section of this manual.
• At least once a year, you should replace the spark plug
and check belts for wear. A new spark plug will help
your engine run better and last longer.
• Follow the maintenance schedule in this manual.
NOTE: Use only Original Equipment Manufacturer (OEM)
parts to service this unit. Failure to do so can cause the unit
to malfunction and pose a risk of injury to the operator.
Maintenance section
➁ Engine
oil
➀ Pivot points
BEFORE EACH USE
1. Check engine oil level.
2. Check for loose fasteners.
3. Check controls to be sure they are functioning properly.
LUBRICATION
Keep your snow thrower well lubricated
(See “LUBRICATION CHART”).
SNOW THROWER
Always observe the safety rules when performing any
maintenance.
•
TIRES
• Maintain proper air pressure in both tires (14–17 P.S.I.).
15
Keep tires free of gasoline and oil, which can harm
rubber.
NOTE: To seal tire punctures and prevent flat tires due
to slow leaks, tire sealant may be purchased from your
local parts dealer. Tire sealant also prevents tire dry rot
and corrosion.
MAINTENANCE
BELTS
Check belts for deterioration and wear after every 50 hours
of operation and replace if necessary. The belts are not
adjustable. Replace belts if they begin to slip from wear.
(See “TO REMOVE BELT COVER” in the Service and
Adjustments section of this manual).
The belts on your snow thrower are of special construction
and should be replaced by original equipment manufacturer
(OEM) belts available from your nearest dealer. Using other
than OEM belts can cause personal injury or damage to
the snow thrower.
TO CHANGE ENGINE OIL
Determine temperature range anticipated before next oil
change. All oil must meet API service classification SJ–SN.
• Be sure snow thrower is on level surface.
• Oil will drain more freely when warm.
• Catch oil in a suitable container.
NOTE: The left side wheel may be removed from snow
thrower for easier access to the oil drain plug and placement of a suitable container. The unit tilted, resting on the
frame with the left wheel removed, will help drain any oil
trapped inside the engine. (See “TO REMOVE WHEELS”
in the Service and Adjustments section of this manual).
1. Remove safety ignition key and disconnect spark plug
wire from spark plug and place wire where it cannot
come in contact with plug.
2. Clean area around drain plug.
3. Remove drain plug and drain oil in a suitable container.
4. Install drain plug and tighten securely.
5. Wipe off any spilled oil from snow thrower and engine.
6. Install left wheel (if removed for draining oil). Be sure
to install wheel pin and retainer pin into proper hole
in wheel axle (See “TO REMOVE WHEELS” in the
Service and Adjustments section of this manual).
7. Remove oil fill cap/dipstick. Be careful not to allow dirt
to enter the engine.
8. Refill engine with oil through oil dipstick tube. Pour
slowly. Do not overfill. For approximate capacity see
“PRODUCT SPECIFICATIONS” section of this manual.
9. Use gauge on oil fill cap/dipstick for checking level.
Be sure dipstick cap is tightened securely for accurate
reading. Keep oil at “FULL” line on dipstick.
10. Wipe off any spilled oil.
AUGER GEAR CASE
• The gear case was filled with lubricant to the proper
level at the factory. The only time the lubricant needs
attention is if service has been performed on the gear
case.
• If lubricant is required, use only Ronex ED #1 grease.
TRACTION DRIVE SYSTEM
DO NOT lubricate or add oil to the hydrostatic transmission
inside your snow thrower. This is a closed system and does
not require maintenance.
ENGINE
See engine manual.
LUBRICATION
Use only high quality detergent oil rated with API service
classification SJ–SN. Select the oil's SAE viscosity grade
according to your expected operating temperature.
MUFFLER
Inspect and replace corroded muffler as it could create a
fire hazard and/or damage.
SPARK PLUG
Replace spark plug at the beginning of each season or after
every 100 hours of operation, whichever occurs first. Spark
plug type and gap setting are shown in the “PRODUCT
SPECIFICATIONS” section of this manual.
NOTE: Although multi-viscosity oils (5W30, 10W30 etc.)
improve starting in cold weather, these multi-viscosity oils
will result in increased oil consumption when used above
32°F. Check your engine oil level more frequently to avoid
possible engine damage from running low on oil.
Change the oil after every 25 hours of operation or at least
once a year if the snow thrower is not used for 25 hours
in one year.
Check the crankcase oil level before starting the engine and
after each five (5) hours of continuous use. Tighten oil fill
cap / dipstick securely each time you check the oil level.

CARBURETOR
Your carburetor is not adjustable. Engine performance
should not be affected at altitudes up to 2,134 meters. If
your engine does not operate properly due to suspected
carburetor problems, take your snow thrower to a service
center/department.
ENGINE SPEED
Never tamper with the engine governor, which is factory set
for proper engine speed. Overspeeding the engine above
the factory high speed setting can be dangerous and will
void the warranty. If you think the engine-governed high
speed needs adjusting, contact a service center/department, which has the proper equipment and experience to
make any necessary adjustments.

•
•
•
Remove safety ignition key; store it in a safe place.
Do not store gasoline from one season to another.
Replace your gasoline can if your can starts to rust.
Rust and/or dirt in your gasoline will cause problems.
• If possible, store your snow thrower indoors and cover
it to protect it from dust and dirt.
• Cover your snow thrower with a suitable protective
cover that does not retain moisture. Do not use plastic.
Plastic cannot breathe, which allows condensation to
form and will cause your snow thrower to rust.
IMPORTANT: Never cover snow thrower while engine/exhaust area is still warm.
ENGINE
See engine manual.
FUEL SYSTEM
IMPORTANT: It is important to prevent gum deposits from
forming in essential fuel system parts such as carburetor,
fuel hose, or tank during storage. Also, alcohol blended
fuels (called gasohol or using ethanol or methanol) can
attract moisture which leads to separation and formation
of acids during storage. Acidic gas can damage the fuel
system of an engine while in storage.
• Empty the fuel tank by starting the engine and letting
it run until the fuel lines and carburetor are empty.
• Never use engine or carburetor cleaner products in
the fuel tank or permanent damage may occur.
• Use fresh fuel next season.
NOTE: Fuel stabilizer is an acceptable alternative in minimizing the formation of fuel gum deposits during storage.
Add stabilizer to gasoline in fuel tank or storage container.
Always follow the mix ratio found on stabilizer container.
Run engine at least 10 minutes after adding stabilizer to
allow the stabilizer to reach the carburetor. Do not empty
the gas tank and carburetor if using fuel stabilizer.
