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

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
