ITS WARNING!

Your Responsibility

Restrict the use

of this power machine

to persons who read,

understand

and follow the warnings

and instructions

in this manual

and on the machine.

DANGER: This machine was built to be operated according to the safe operation practices in this

manual. As with any type of power equipment, carelessness or error on the part of the operator can

result in serious injury. This machine is capable of amputating hands and feet and throwing objects.

Failure to observe the following safety instructions could result in serious injury or death.

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.

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 operat-

ing on 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.

13. Never operate this machine without good visibility or light.

Always be sure of your footing and keep a firm hold on the

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.

Always use the clean-out tool provided to unclog the dis-

charge opening. 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. Call customer assistance for the

name of your nearest servicing dealer.

Maintenance & Storage

1. Never tamper with safety devices. Check their proper

operation regularly. Refer to the maintenance and adjust-

ment sections of this manual.

2. Before cleaning, repairing, or inspecting machine disengage

all control levers and stop the engine. Wait until the auger/

impeller come to a complete stop. Disconnect the spark plug

wire and ground against the engine to prevent unintended

starting.

3. Check bolts and screws for proper tightness at frequent

intervals to keep the machine in safe working condition.

Also, visually inspect machine for any damage.

4. Do not change the engine governor setting or over-speed

the engine. The governor controls the maximum safe

operating speed of the engine.

5. Snow thrower shave plates and skid shoes are subject to

wear and damage. For your safety protection, frequently

check all components and replace with original equipment

manufacturer’s (OEM) parts only. “Use of parts which do

not meet the original equipment specifications may lead to

improper performance and compromise safety!”

6. Check controls periodically to verify they engage and

disengage properly and adjust, if necessary. Refer to the

adjustment section in this operator’s manual for instructions.

7. Maintain or replace safety and instruction labels, as neces-

sary.

8. Observe proper disposal laws and regulations for gas, oil,

etc. to protect the environment.

9. Prior to storing, run machine a few minutes to clear snow

from machine and prevent freeze up of auger/impeller.

10. Never store the machine or fuel container inside where

there is an open flame, spark or pilot light such as a water

heater, furnace, clothes dryer etc.

11. Always refer to the operator’s manual for proper instructions

on off-season storage.

12. Check fuel line, tank, cap, and fittings frequently for cracks

or leaks. Replace if necessary.

13. Do not crank engine with spark plug removed.

Do not modify engine

To avoid serious injury or death, do not modify engine in any

way. Tampering with the governor setting can lead to a runaway

engine and cause it to operate at unsafe speeds. Never tamper

with factory setting of engine governor.

WARNING

Read, understand,

and follow all instruc-

tions and warnings

on the machine and

in this manual before

operating.

Use extreme care

when handling

gasoline. Gasoline is

extremely flammable

and the vapors are

explosive. Never fuel

the machine indoors

or while the engine

is hot or running.

Extinguish cigarettes,

cigars, pipes and

other sources of

ignition.

Shift Lever

The shift lever is located in the center of

the handle panel and is used to determine

ground speed and direction of travel. It can

be moved into any of eight positions.

IMPORTANT: Always release drive control

before changing speeds.

Forward: The snow thrower has six

forward (F) speeds. Position one (1) is the

slowest and position six (6) is the fastest.

Reverse: The snow thrower has two

reverse (R) speeds—R1 is the slower of

the two.

Operating

Your Snow

Thrower

WARNING

The operation of

any snow thrower

can result in foreign

objects being thrown

into the eyes, which

can damage your

eyes severely. Always

wear safety glasses

while operating the

snow thrower, or while

performing any adjust-

ments or repairs on it.

Be sure no one other

than the operator is

standing near the snow

thrower while starting

engine or operating

snow thrower. Never

run engine indoors or

in enclosed, poorly

ventilated areas. En-

gine exhaust contains

carbon monoxide, an

odorless and deadly

gas. Keep hands, feet,

hair and loose clothing

away from any moving

parts on engine and

snow thrower.

Auger Control

The auger control is located on the left handle. Squeeze

the auger control to engage the augers. Release to stop

the snow throwing action. The drive control must also be

released in order to stop auger.

Drive Control / Auger Control Lock

The drive control is located on the right handle. Squeeze

the drive control to engage the wheel drive. Release to

stop.

This same lever also locks the auger control so you

can operate the chute crank without interrupting the

snow throwing process. If the auger control is engaged

simultaneously with the drive control, the operator can

release the auger control (on the left handle) and the

augers will remain engaged. Release the drive control to

stop the augers and wheel drive (the auger control must

also be released).

IMPORTANT: NEVER reposition the shift lever (change

speeds or direction of travel) without first releasing the

drive control and bringing the snow thrower to a complete

stop. Doing so will result in premature wear to the snow

thrower’s drive system.

Heated Handles Switch (If Equipped)

This switch is located on the right side of the snow

thrower dash panel. To activate the heated handles,

toggle the switch to the “ON” position to generate heat

within the handle grips. Toggle the switch to the “OFF”

position after using the snow thrower.

NOTE: The heated handles grips are a compliment to,

not a substitute for, proper cold weather outerwear for

the operator’s hands. It is recommended that the snow

thrower operator wear gloves/mittens to avoid extremities

of winter while operating this equipment.
