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 before every
plowing season and frequently throughout the
season. Replace cutting edges before wear is
into wing or mast sections to avoid damage to
these components.
The 5/16" hex bolts in the latch sliders are fac-
tory retained with anaerobic threadlock. If re-
moval or replacement of these bolts is neces-
sary, purchase new bolts with threadlocker from
your Hiniker dealer, or apply a commercially
available threadlock, i.e., Loctite 242 (blue) to
standard 5/16-18 x 3/4" grade 5 hex bolts be-
fore 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. A light coat of dielectric grease is recom-
mended to reduce corrosion of the contacts and
to make connecting and disconnecting easier.
Before each season check the vehicle battery
and electrical system for proper operation. A
weak battery, dirty terminals, or faulty charging
system may cause improper operation and pos-
sible failure of the joystick controller.
Before every plowing season, and throughout
the season, check the snowplow headlamps for
proper function and aim.
