After each snow removal session, run the Snow
Thrower for a few minutes to prevent the
collector/impeller from freezing. Stop the engine,
wait for all revolving parts to stop completely, and
wipe residual ice and snow off the unit. Rotate
the chute rotation handle several times to remove
any excess snow.

Maintenance Procedures

Tire Inflation
Before each use of your Snow Thrower, check
the tire pressure. The pressure in each tire
should be in the range of 20-24 psi for the best
performance. The pressure can be checked
using an ordinary tire pressure gauge. Fill the
tires using an small or pressure regulated air
compressor.
WARNING! DO NOT OVER-INFLATE THE
TIRES. Over-inflating could cause a tire to
burst and cause severe bodily injury.
Shave Plate Replacement
Remove both skid shoes and hardware including
carriage bolts and nuts which attach shave plate
to snow thrower housing. Reassemble new
shave plate, making sure heads of the carriage
bolts are to the inside of the housing.

WARNING! The auger and impeller rotate at
fast speeds which can cause harm or even
amputation to a person's body parts. Even if
you do not see the auger or impeller rotating,
it may start at any time if the engine is running.
The chute clean-out tool is fastened to the top of
the auger housing with a mounting clip and a
cable tie at the factory. Cut the cable tie before
operating the snow thrower.
1. Always turn OFF the engine before attempting
to clear any clogs or jams.
2. Keep hands and feet away from rotating parts
while the engine is running.
3. Do not wear loose fitting clothing that can
become entangled in rotating parts.
4. Wait until the auger and impeller have come to
a full stop.
5. Clear any visible jams using the clean out tool
attached to your machine.
WARNING! DO NOT try to clear jams with your
hands or feet.

Auger Shear Pin Replacement

Shear pins are used to attach the auger shaft to
the auger blades. A clog or jam in the augers
may cause one or multiple shear pins to break.
The shear pins are a safety mechanism and
designed to break under high load or impact to
protect the auger drive system from damage.
Replacement shear pins and nylon locknuts are
provided with your snow thrower. For additional
replacement shear pins, please call the customer
service department.
