Maintenance
Lubrication
Periodically lubricate the pivot points
between the tongue and pivot plate
with an all-purpose automotive type
grease. Periodically spray lube the pivot
latch components. See Figure 20.
Adjustments
Skid Shoes
NOTE:
Adjust the skid shoes so the plow cutting
edge just clears the surface to be plowed when
being used for snow removal.
Adjust the skid shoes to the appropriate
position for the job being performed. See
Figure 21.
1. Loosen the jam nuts on each shoe.
2. Turn the skid shoes to the desired
position.
3. Tighten all applicable jam nuts.
Plow Lift Cable Tension Adjustments
1. Using the two nuts on the ferrule,
adjust tension on the cable using
ferrule position so that locking pin
retracts and clears the inside of
the front mounting bracket. See
Figure 22.
2. Test the tension by squeezing the
trigger against the handle and
raising and lowering the plow.
Pivot Release Cable
Tension Adjustments
1. Using the two nuts on the ferrule,
adjust tension on the cable using
ferrule position so that the pivot
locking lever fully clears the pivot
plate by at least 1/8". See Figure
23.
2. With the plow locked in the lift
position, test by squeezing the
trigger against the handle and
pushing/pulling the control
handle to pivot the plow. Plow
should pivot freely.

If the shave plate becomes worn, rotate or replace the bar as follows. See Figure 24.
1. Remove the six carriage bolts and
flange lock nuts fastening the
shave plate to the plow.
2. Rotate or replace the shave plate
and attach with the carriage bolts
and flange lock nuts.
NOTE: When the shave plate is
reinstalled, adjustment of the skid
shoes may be required.
Trip Spring
Maintain the proper trip spring tension as
described below. See Figure 25.
1. There should be a 1 3/8" - 1 1/2"
max gap between the top of the
threaded rod and the upper lip of
the plow.
2. Tighten or loosen the nuts to
obtain the proper gap.
IMPORTANT: Gap setting may vary
depending on material being moved.
