Maintenance; Adjustments; Lubrication; Cutting Edge Maintenance - Sears C 151 61822 4 Owner's Manual

Refer to parts breakdown section for parts
identification.
WARNING
TO PREVENT INJURIES:
Stop the motor.
Apply parking brake.
Remove the ignition key.
Disconnect the wire from the spark plug(s) and
keep away from spark plug(s) to prevent accidental
starting.
CAUTION
TO PREVENT INJURIES:
-Check mounting bolts at frequent intervals for
proper tightness in order to prevent costly repairs.
-Make sure your snowblower is in safe working
condition.
-Provide adequate blocking before working under
snowblower when in raised position.

ADJUSTMENTS

SKID SHOE ADJUSTMENT:
Level Paved Surface: Adjust skid shoes to obtain 3/16"
to 1/4" clearance between cutting edge and surface.
Uneven or Gravel Surface: Adjust skid shoes to obtain
1/2" to 5/8" clearance between cutting edge and
surface.
CHAIN ADJUSTMENT:
Auger drive chain: Set chain tension leaving 1/2"
deflection in chain span. Retighten hex bolt securely.

LUBRICATION

Apply oil at all pivot points.
Drive Chains: Lubricate with chain saw chain lubricant
every eight hours of operation.
Chute Rotation System: Oil chute base, rotation worm
every eight hours of operation.

CUTTING EDGE MAINTENANCE

Verify from time to time the wear on the cutting edge
to make sure you do not wear out the base of the
snowblower's frame. This cutting edge is reversible.

GENERAL MAINTENANCE

a) Check mounting bolts at frequent intervals for
proper tightness to be sure equipment is in safe
working condition.
b) Apply oil at all pivot points.
c) To prolong the life span of the winch, make sure the
snap mount switch works well.

MAINTENANCE

SHEAR
REPLACEMENT
Shear bolts and shear pins are to be considered a
preventive measure and not an assured protection.
Operator vigilance is required. Thoroughly inspect
the areas where the snowblower is to be used and
remove all foreign objects.
Fan Shear Bolt Replacement:
The fan is protected by a special shear bolt with two
grooves. If you hit a foreign object or ice, the shear bolt
is designed to break in two upon absorbing impact. The
fan will stop turning. This is to avoid damage to the fan
or to the snowblower. Replace only with original parts.
Auger Shear Pin Replacement:
The auger is protected by a special nylon shear pin. If
you hit a foreign object or ice, the shear pin is designed
to break in two upon absorbing impact. The auger will
stop turning. This is to avoid damage to the auger or the
snowblower. Replace only with original parts.
WINCH CABLE MAINTENANCE
To reduce the risk of cable failure during the season,
we recommend changing the winch cable every year.
Install the new winch cable as shown in figure in the
parts breakdown.
Lubricate the winch cable and the drum periodically
with grease.
BELT REPLACEMENT
Drive Mechanism Belt:
a) Dismount the drive mechanism.
b) Remove the bolt which retains the tension
pulley.
c) Replace the belt and re-install the tension
pulley. Before tightening make sure the belt
guide does not touch the belt at any time.
d) Re-install the drive mechanism.
e) Check the alignment of the belt that joins the
drive mechanism to the engine pulley.
