MAINTENANCE AND ADJUSTMENT
Your BLIZZARD
®
snowplow is designed for rugged,
dependable service. However, like the vehicle
on which it is mounted, it needs regular care and
maintenance.
Check the following before and frequently during the
plowing season:
1. Make sure that all fasteners, mounting bolts, and
hydraulic connections are tight. Pay particular
attention to the 1" pivot bolt.
2. Check all plugs and seals for hydraulic
fl
uid leaks.
Repair as necessary.
CAUTION
Overtightening springs will not increase blade
trip force and can damage the springs.
WARNING
Lower the blade when the vehicle is parked.
Keep 8 feet clear of the blade when it is being
raised, lowered, or angled. Temperature
changes could change hydraulic pressure,
causing the blade to drop unexpectedly or
damaging hydraulic components. Failure to
do this could result in serious personal injury.
3.
Trip Spring Adjustment:
To adjust trip spring
tension, adjust the eyebolts located at the top
of the blade. Tighten the adjusting nut until the
coils begin to separate. When tension is properly
adjusted, a sheet of paper should pass between
the second and third coils. When the proper
tension is reached, tighten locknut.
4.
Blade Finish:
If the powder-coated
fi
nish is
nicked or scratched, repair the surface and paint
with BLIZZARD white or black paint (available in
aerosol or quart cans).
