SECTION 1:  IMPORTANT SAFE OPERATION PRACTICES

DANGER: This machine was built to be operated according to the rules for safe operation 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.

Training

1.

Read, understand, and follow all instructions on the 
machine and in the manual(s) before attempting to 
assemble and operate. Keep this manual in a safe place 
for future and regular reference and for ordering 
replacement parts. 

2.

Be familiar with all controls and their proper operation. 
Know how to stop the machine and disengage them 
quickly.

3.

Never allow children under 14 years old to operate this 
machine. Children 14 years old and over should read and 
understand the operation instructions and safety rules in 
this manual and should be trained and supervised by a 
parent. 

4.

Never allow adults to operate this machine without 
proper instruction. 

5.

Thrown objects can cause serious personal injury. Plan 
your snow-throwing pattern to avoid discharge of material 
toward roads, bystanders and the like. 

6.

Keep bystanders, helpers, pets and children at least 75 
feet from the machine while it is in operation. Stop 
machine if anyone enters the area.

7.

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. Remove all doormats, newspapers, sleds, 
boards, wires and other foreign objects, which could be 
tripped over or thrown by the auger/impeller.  

2.

Always wear safety glasses or eye shields during 
operation and while performing an adjustment or repair to 
protect your eyes. Thrown objects which ricochet can 
cause serious injury to the eyes.

3.

Do not operate without wearing adequate winter outer 
garments. Do not wear jewelry, long scarves or other 
loose clothing, which could become entangled in moving 
parts. Wear footwear which will improve footing on 
slippery surfaces. 

4.

Use a grounded three-wire extension cord and 
receptacle for all units with electric start engines. 

5.

Adjust collector housing height to clear gravel or crushed 
rock surfaces. 

6.

Disengage all clutch levers before starting the engine. 

7.

Never attempt to make any adjustments while engine is 
running, except where specifically recommended in the 
operator’s manual.

8.

Let engine and machine adjust to outdoor temperature 
before starting to clear snow. 

9.

To avoid personal injury or property damage use extreme 
care in handling gasoline. Gasoline is extremely 
flammable and the 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 
where there is an open flame, spark or pilot light 
(e.g. furnace, water heater, space heater, clothes 
dryer etc.).  

j.

Allow machine to cool at least 5 minutes before 
storing.

Operation 

1.

Do not put hands or feet near rotating parts, in the auger/
impeller housing or discharge chute. Contact with the 
rotating parts can amputate hands and feet. 

2.

The auger/impeller clutch lever is a safety device. Never 
bypass its operation. Doing so makes the machine 
unsafe and may cause personal injury. 

3.

The clutch levers must operate easily in both directions 
and automatically return to the disengaged position when 
released. 

4.

Never operate with a missing or damaged discharge 
chute. Keep all safety devices in place and working.
