Safety Rules
WARNING
This unit is a “two-stage” snowthrower. The first
stage is the auger, which feeds the snow back into
the impeller housing. The second stage is the
impeller, which throws the snow out the discharge
chute. If bodily contact is made with the auger or
impeller when they are rotating, severe personal
injury will occur. To avoid injury, keep others and
yourself away from the auger and the discharge
chute whenever the engine is running. Read and
follow all of the safety rules and warnings in this
manual.
A
WARNING
To avoid serious injury, do not put your hands into
the auger housing or discharge spout. If auger
stalls or spout becomes plugged, use the following
procedure to remove objects or clear the spout:
1.
Release both drive levers.
2. Shut off the engine.
3. Wait for moving parts to stop.
4. Use a narrow board to remove foreign objects
and clear the spout or auger. Never put your
hands into the auger or discharge spout.
GENERAL
. Read the Operator’s Manual carefully. Be thoroughly
familiar with all controls and proper equipment use.
l Never allow children to operate the machine. Do not
allow adults to operate it without proper instruction.
. Keep the area of operation clear of all persons, par-
ticularly small children and pets.
l Never discharge material toward any person or pet.

DEFLECTOR
The angle and distance of the discharged snow is controlled by the position of the deflector. Engine speed also
affects distance of discharge.
The more the deflector is tilted back, the farther snow will
be thrown. Loosen the knob (figure 3) to tilt the deflector
back or forward, then retighten the knob.
SCRAPER BAR
On smooth surfaces such as concrete or asphalt, the
scraper bar should scrape the surface. On surfaces such
as gravel, the scraper bar should be high enough so that
it will not pick up gravel or debris.
The height of the scraper bar is controlled by raising or
lowering the skid shoes as shown in figure 4.
1. To raise the scraper bar height, rest the scraper bar
on a piece of wood, equal in thickness to the desired
height.’
2. Make sure the scraper bar is parallel to the ground
surface.
3. Loosen the skid shoe nuts and let the skid shoes
drop to the surface.
4. Tighten the nuts, making sure the skid shoes are
adjusted equally and are parallel to the surface.
5. To lower the height of the scraper bar, raise the skid
shoes.
6. If the scraper bar becomes worn, it can be replaced
by removing the hardware attaching it to the
snowthrower, installing a new one and then tightening the hardware.

SHEAR PIN REPLACEMENT,
If the auger strikes an object which could cause damage
to the unit, the shear pin will break. This protects the
gear box and other parts from damage. The shear pins
are shown in figure 15. To replace, install a new shear
pin and cotter pin. Spread the legs of the new cotter pin
fully. Do not replace shear pins with bolts, screws or a
harder shear pin.
