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

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.

if drive chain jumps off sprockets, wheel axle bearings may need to be replaced.
1. Disconnect spark plug wire and fasten it away from the spark plug.
2. Place a block under the snowthrower so the wheels are just off the ground.
3. See figure 16. Remove the ring pin and wheel from each axle.
4. Slide off the washers and long spacer.
A
CAUTION
Note the number and placement of washers used between wheel and long spacer, or between long spacer and bearing. An even number of washers must be used on each side of the shaft.
