Auger Or Impeller Jams; Auger Shear Pin Replacement - Power smart DB7659A-22 User Manual

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.
