MAINTENANCE/STORAGE AND FINAL COMMENT
Maintenance
Inspect the plow before each
use. The mold board surface will
become scratched with use. It is
recommended to apply wax or a
nonstick spray to the surface
before plowing. This will prevent
the snow from sticking to the blade
and provide the best material roll.
Inspect the blade wear bar.
This steel or plastic bar on the
bottom of the blade will need to be
replaced periodically over the life of
the plow. The steel bar provides
about ¾” (19mm) of wear material
before requiring replacement.
Some blades have a reversible bar
that may be turned to double the
life of the bar. This bar must be
replaced before the retaining bolts
and nuts begin to contact the
ground.
The blade hinge bushings will
require lubrication periodically for
the best plow performance. Spray
a light lubricating oil on both sides
of the center blade ribs just above
the large hinge bolt. This lubrica-
tion should run down the rib and
into the bushing area. For better
results the blade retaining M16
nuts and retaining washers should
be removed to allow lubrication to
be applied directly to the bushing.
The blade pivot bushing is
located in the center of the plow
base. Remove the plow from the
vehicle and place the blade face
down so that the plow base and
bushing are vertical. Spray a light
lubricating oil around the base
retaining plate and then rotate the
tube assembly a few times to either
side. Repeating this a few times
will allow the oil to enter the pivot
bushing area. The base retaining
plate may need to be removed for
cleaning and thorough lubrication if
the pivot assembly does not turn
smoothly.
Inspect all fasteners to insure
that they are tight. The fasteners
on your plow must be torqued
periodically to insure that they are
tight. Torque the fasteners to the
following specifications:
- 13mm (M8) Bolts – 17 N-m (12
ft-lb)
- 17mm (M10) Bolts – 42 N-m (31
ft-lb)
- 24mm (M16) Bolts – 138 N-m
(100 ft-lb)
Storage
Always clean off your plow by
spraying with fresh water before
storage. This will minimize
corrosion from road salts or other
chemicals. Once the plow is clean
it should be removed from the
vehicle. Spray pivots and bushings
with light lubricating oil and place in
storage area. The storage area
should be clean and dry.
Always repair and lubricate
prior to storage, making the plow
ready for your next use.
Final Comment
The Plow Operator’s Guide
cannot cover all the possible
situations in which you may use
your plow. The decisions you make
will determine the final outcome.
So think through each situation
before you begin to move material.
Read and understand all manuals,
labels and tags. Always be mindful
of your own safety and the safety of
others.
