Safe  

Operation 

Practices

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 control 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 refuel-

ing.

  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 equip-

ment. 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.
