Regular Maintenance
Your Blizzard straight blade snowplow has been designed for years of
rugged, dependable service with low maintenance. To ensure proper
working condition, follow the maintenance guidelines below and on the
next page.
CAUTION: Always follow the maintenance guidelines in a timely
fashion. Failure to observe maintenance guidelines may result
in poor snowplow operation, increased component wear or
possibly lead to part failure.
Routinely inspect the following items – perform maintenance as needed:
1. All fasteners, pins, nuts and bolts for tightness. See the recommended
maximum bolt torque chart on page 33.
2. All hydraulic hoses and hydraulic hose adapters for wear and leaks.
See the recommended hydraulic adapter torque values on page 33.
3. All cylinders for leaks; inspect rod ends for corrosion and pitting.
4. Cutting edges and plow shoes for wear. Do not discard plow shoe
washers. These should be retained for different shoe adjustments.
5. Clean and lubricate all electrical plugs, headlight connections, ground
and battery cables, solenoid connections and switch connections to
prevent corrosion. Apply dielectric grease for every 25 hours of snow-
plow use.You may need to grease more frequently depending on your
plowing environment.
6. Lubricate all pins and bushings to prevent corrosion and to maintain
consistent operation. A NLGI Grade 2 multipurpose lithium complex
grease with molybdenum (MPGM) is recommended for lubrication.
7. Clean and cover deep scratches or exposed metal with Blizzard Snow-
plow white (P/N 61219) or black (P/N 63073) touch-up paint. Contact
your local Blizzard Dealer for availability.
8. Check the hydraulic oil level in the hydraulic pump fluid reservoir. Fill
the fluid to within 3/4" from the top of the reservoir. Do not exceed this
level. Never mix different types of fluids. Contact your local dealer for
replacement Blizzard Snowplow Rapid Action Hydraulic Oil (P/N 63070).
9. Check the trip spring adjustment. Properly adjusted tension will allow
a sheet of paper to pass between the 3rd and 4th coils of the spring.
10. To adjust the snowplow drop speed, use the variable flow control valve
(FC) on the manifold (see label under pump & manifold cover).Turn the
dial on the valve clockwise to decrease the drop speed. Turn the dial
counterclockwise to increase the drop speed.See the Troubleshooting
Guide on page 35 for additional instructions.
11. Do not allow snow and ice to build-up on the pump and manifold cover.
Excessive build-up may cause bumper damage when the plow is raised.
