NOTE: PROTECTION AGAINST RUST AND CORROSION
When the power unit is not used for extended periods, protect the chromed
lift piston fully extending and coating it with chassis lubricant. Coat the
exposed portions of the power angling cylinder rods with chassis lubricant
to protect against corrosion.
Post-Season Summer Maintenance
1. Draining & Replacing Meyer M-1 Hydraulic Fluid
Drain fluid through drain hole in base, shown in Figure a 0-3, by
completely retracting cylinder lift position and unbolting unit to pour
fluid out, or use a suction pump. Disconnect the fittings at the Power
Angling cylinders, completely retract the cylinder rods and purge
cylinders and hoses of all hydraulic fluid. The complete hydraulic
system should then be flushed out with clean mineral spirits or
hydraulic oil before adding new Meyer M-1 Hydraulic Fluid.
2. Screen-Type Filters - Clean the filters (all models) with mineral spirits
or equivalent and blow out with compressed air. See Figure 0-3.
3. Diamond Hydraulic Fluid M-1 is specially formulated with an anti-ice
additive for almost constant viscosity in subzero temperatures.
Because it is free-flowing in extreme cold, the unit's performance and
efficiency are not affected by winter weather. It is effective for a
maximum of one year. Always carry an extra quart of Meyer Hydraulic
Fluid M-1 or equal fluids. Use of any inferior fluids will void the
Diamond warranty.
4. Refill power unit with Meyer Hydraulic Fluid M-1 by fully retracting lift
piston and filling reservoir to 1 1/2’’ below the filler hole. Fill and bleed
hoses and Power Angling cylinders by loosening hydraulic fittings at
cylinders until they leak. Power angle the plow repeatedly from one
side to the other until fluid flows steadily from the fittings while
maintaining a constant check on the reservoir fluid level. The filling end
of the cylinder should be higher than the piston end to facilitate
removal of air. Raise and lower the plow several times. With lift rod fully
retracted check fluid level and replace filter plug.
SNOWPLOW STORAGE
1. When snowplow is disconnected, extend lift cylinder to end of
stroke and coat chrome rod with light grease. This fills the cylinder
with hydraulic fluid and protects the interior and exterior from rust
and corrosion.
2. Whenever Moldboard is disconnected, coat the exposed portions of
the power angling cylinder chrome rods with light grease to protect
them from corrosion.
3. Be sure to reconnect quick couplers to keep them clean and prevent
contamination of the system.
4. Coat all pivot pins and other wear points with chassis lubricant.
5. Unplug all electrical connections at power unit. Coat all connections
with a dielectric compound to prevent corrosion and plug into their
corresponding weather plugs. Unplug the snowplow lights, tape or
use a dielectric compound at light connections to prevent corrosion.
6. Remove PULL-AWAY™ lift frame module from vehicle. Liberally
coat insides of frame receiver tubes and ends of lift frame with
chassis grease/anti-seize lubricant. Protect frame receiver tubes
from dirt and other types of contamination by installing the receiver
tube caps when the lift frame is removed from the vehicle
7. WARNING: Lift arm extends beyond bumper of vehicle. To
minimize damage from a front-end collision, lift arm should be
removed from vehicle when snowplow is removed.
