MECHANICAL COMPONENTS
Prior to the operation of a new snowplow, or one
which has been stored, inspect all hardware and
verify proper torque on all bolts and nuts in ac-
cordance with the recommended torque speci-
fications.

*applications without lock nuts.
Loose bolts can cause hole elongation and part
failure resulting in dangerous operating condi-
tions and equipment breakdown.
Check all hardware periodically during the plow-
ing season and keep tightened to specified
torques. Replace worn bolts and lock nuts with
grade 5 bolts and equivalent type B or type F
lock nuts. Type B lock nuts are plain hex; type F
lock nuts are flanged hex.
Inspect wear of the cutting edges and the cen-
ter cone before every plowing season and fre-
quently throughout the season. Replace cutting
edges and the center cone before wear is into
wing or mast sections to avoid damage to these
components.
The three 5/8 inch flat socket head screws that
fasten the center cone to the bottom of the plow
are factory retained with anaerobic threadlock-
er. If removal or replacement of these screws is
necessary, purchase new screws with thread-
locker from your Hiniker dealer or apply a com-
mercially available threadlock, i.e., Loctite 242
(blue) to the threads before reassembly. Torque
all three screws to 125 Ft. lbs (170 N-m).

Once a year before using the plow, check that
the plow will trip freely about its trip pin. With
the plow mounted on the truck and lowered to
the ground, loosen the four trip springs and pull
the top of the moldboard forward. If the mold-
board doesn't pivot freely, remove the trip pin
and apply a commercially available anti-seize
lubricant. Damage to the plow or truck may re-
sult if the moldboard hits an obstruction during
use and doesn't trip.
Retighten the trip springs by turning the nuts on
the spring studs until the coils begin to sepa-
rate. Secure spring studs by tightening top and
bottom nuts together to produce a rigid clamp.
At least once a year, grease the center hinge
pin on the moldboard by injecting a high quality,
general purpose grease into each bushing pin
hole with a grease syringe.
Grease the adjustable stop bolt behind the cen-
ter mast at least once a year with a high quality,
general purpose grease to prevent corrosion.
The 5/16" hex bolts in the latch sliders are facto-
ry retained with anaerobic threadlock. If remov-
al or replacement of these bolts is necessary,
purchase new bolts with threadlocker from your
Hiniker dealer, or apply a commercially avail-
able threadlock, i.e., Loctite 242 (blue) to stan-
dard 5/16-18 X 3/4" grade 5 hex bolts before
reassembly.
ELECTRICAL MAINTENANCE
Periodically check all electrical connections for
proper fit and remove any contamination that
may be present.
To prevent contamination always place dust
caps on connectors when not in use. This is
particularly important when the plow is being
stored. The use of dielectric grease is recom-
mended to reduce corrosion of the contacts and
to make connecting and disconnecting easier.
Before each season check vehicle battery and
electrical system for proper operation. A weak
battery, dirty terminals, or faulty charging sys-
tem may cause improper operation and possible
failure of the joystick controller.
