AND OTHERS. READ AND FOLLOW ALL INSTRUCTIONS IN THIS MANUAL BEFORE ATTEMPTING
TO OPERATE YOUR SNOW THROWER. FAILURE TO COMPLY WITH THESE INSTRUCTIONS MAY
RESULT IN PERSONAL INJURY. WHEN YOU SEE THIS SYMBOL-HEED ITS WARNING.

DANGER:  

Your snow thrower attachment 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. If you violate any of these rules, you may cause serious injury to 
yourself or others.

1.

TRAINING

Read this operator's manual carefully in its entirety 
before attempting to assemble or operate this 
machine. Be completely familiar with the controls 
and the proper use of this machine before operating 
it. Keep this manual in a safe place for future and 
regular reference and for ordering replacement 
parts.

Allow children under 14 years old to operate the 
tractor with a snow thrower attachment ONLY under 
close parental supervision. Only persons well 
acquainted with these rules of safe operation should 
be allowed to use the snow thrower.

No one should operate this unit while intoxicated or 
while taking medication that impairs the senses or 
reactions.

Keep the area of operation clear of all persons, 
especially small children and pets.

Exercise caution when operating the tractor with the 
snow thrower attachment, especially when traveling 
in reverse.

2.

PREPARATION

Thoroughly inspect the area where the equipment is 
to be used and remove all door mats, sleds, boards, 
wires and other foreign objects.

Do not operate equipment without wearing 
adequate winter outer garments. Do not wear 
jewelry, long scarfs or other loose clothing which 
could become entangled in moving parts. 

Before working with gasoline, extinguish all 
cigarettes and other sources of ignition. Check the 
fuel before starting the engine. Gasoline is an 
extremely flammable fuel. Do not fill the gasoline 
tank indoors, while the engine is running, or until 
engine has been allowed to cool at least two 
minutes. Replace gasoline cap securely and wipe 
off any spilled gasoline before starting the engine as 
it may cause a fire or explosion.

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

Never attempt to make any adjustments while 
engine is running (except where specifically 
recommended by manufacturer).

Let the tractor’s engine and the machine adjust to 
outdoor temperature before starting to clear snow.

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 in any direction.

3.

OPERATION

Do not put hands or feet near or under rotating 
parts. Keep clear of discharge opening and auger at 
all times.

Exercise extreme caution when operating on or 
crossing gravel drives, walks, or roads. Stay alert 
for hidden hazards or traffic. Do NOT carry 
passengers.

After striking a foreign object, stop the tractor’s 
engine and thoroughly inspect the snow thrower for 
any damage. Repair the damage before operating 
the snow thrower.

If the snow thrower should start to vibrate 
abnormally, stop the tractor’s engine and check 
immediately for the cause. Vibration is generally a 
warning of trouble.

Stop the tractor’s engine whenever you leave the 
operating position, before unclogging the collector/
impeller housing or discharge guide, and making 
any repairs, adjustments, or inspections. Never 
place your hand in the discharge or collector 
openings. Use a stick or wooden broom handle to 
unclog the discharge opening.

Take ALL possible precautions when leaving the 
unit unattended. Disengage power (tractor’s PTO) 
to the collector/impeller, shift the tractor into neutral 
and stop its engine, set the parking brake and 
remove the key.

When cleaning, repairing, or inspecting, make 
certain collector/impeller and all moving parts have 
stopped completely.

Do not clear snow across the face of slopes. 
Exercise extreme caution when changing direction 
on slopes. Do not attempt to clear steep slopes.

Never operate snow thrower without guards, plates, 
or other safety protection devices in place.

Never operate snow thrower near glass enclosure, 
automobiles, window wells, drop offs, etc., without 
proper adjustments of snow thrower discharge 
angle. Keep children and pets away.

Do not overload machine capacity by attempting to 
clear snow at too fast a rate.

Never operate the machine with the tractor at high 
ground speeds on slippery surfaces. Look behind 
and use care when backing.
