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 
operating 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 clutch 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 discharge chute, making any 
adjustments, or inspections. 

18. Never put your hand in the discharge or collector 

openings. Always use the chute clean-out tool provided 
to unclog the discharge opening. Do not unclog 
discharge chute 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. If situations occur which are not covered in this manual, 

use care and good judgment. Contact your dealer or call 
1-800-800-7310 for assistance and 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 
adjustment sections of this manual.

2.

Before cleaning, repairing, or inspecting machine 
disengage all 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 
necessary.

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. 

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. The 
safety labels are shown below for your reference.

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.
