WARNING
m
Make sure to turn off the switch and disconnect the
extension cord before performing any maintenance
task on your snow thrower.
Lifetime Lubrication (Motor + Auger)
Lubrication is not necessary and may damage the unit. The
snow thrower is lubricated for lifetime use at the factory before
shipment.
General Maintenance Tips
1. Do not attempt to repair the machine unless you have the
proper tools and instructions for disassembly and repair of
the machine.
2. Check bolts and screws at frequent intervals for proper
tightness to ensure that the equipment is in safe working
condition.
3. After each snow removal session, run the snow thrower
for a few minutes to prevent the collector/impeller from
freezing. Shut off the motor, wait for all revolving parts to
stop completely and wipe residual ice and snow off the
unit. Rotate the chute crank several times to remove any
excess snow.
Replacing the Rubber Plates
NOTE: When replacing worn rubber plates, pay close attention
to carefully distinguish between the coarse and smooth side of
the plates. Place the coarse side inside and the smooth side
outside.
1. Detach the worn rubber plate assembly by removing the
two sets of nuts and bolts used to secure it to the auger
assembly (Figs. 21 & 22).
2. Loosen the middle two sets of nuts and bolts to detach
the worn rubber plate from the metal frame (Fig. 23).
3. Attach the new rubber plate onto the metal frame by
replacing and tightening the middle two sets of nuts and
bolts (Fig. 23).
4. Reassemble the rubber plate assembly to the auger
assembly by replacing and tightening the two sets of nuts
and bolts used to secure it (Figs. 21 & 22).

WARNING

Make sure that the chute deflector snaps and locks
completely onto the discharge chute. An opening
between the discharge chute and the chute deflector
may allow foreign objects to be picked up by the
snow thrower and thrown in the direction of the
operator causing serious bodily injury.
• Do not advance the chute deflector too far
forward causing an opening to appear between
the
deflector and discharge chute.
•
Do not overtighten the knobs on the chute
deflector
(Fig. 20).
