Auger or Impeller Jams

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. 

1. Turn off the engine and wait for all moving 

parts to come to a complete stop.

Remove any remnants of the broken shear pin. It 
may be necessary to unscrew the nut from the 
broken shear pin and drive out the broken pin.
2. Insert a new shear pin through the hole in the 

auger shaft and tighten using the shear pin 
hex nut. Do not over-tighten the hex nut.

NOTICE: Never replace the shear pins with 
standard pins or fasteners. Damage may occur to 
the snow blower and drive systems.

Drive Control Cable Tension 

Adjustment

WARNING! Entanglement Hazard - Before 
performing any adjustment procedures, make 
sure the engine is off and remove the spark 
plug wire from the spark plug to ensure the 
engine cannot accidently start. Never adjust 
cable tension with the engine running.

The drive control cable is located on the right 
side (when standing behind the snow blower) 
and is made up of an upper and lower cable 
connected by an adjustment plate. The 
adjustment plate is located in-line with the cable 
below the control handle and is covered by a 
black plastic slip cover. The adjustment plate is 
used to adjust the drive control cable drive wheel 
friction tension.
1. Stop the engine.
2. Disconnect the upper cable from the drive 

control handle.
