Annual Fluid Change
Perform this operation with the snowplow
attached to the truck on a hard level surface.
Disable the one‑touch FLOAT feature, if enabled.
(See "One‑Touch FLOAT" in the Operating Your
Snowplow section of this manual.)
MAINTENANCE
CAUTION
Do not mix different kinds of hydraulic
fluid. Some fluids are not compatible and
may cause performance problems and
product damage.
CAUTION
Change the fluid at the beginning of each
plowing season. Failure to do this could
result in condensation buildup during the
non-plowing season.
1. Place jack stands under the A‑frame/T‑frame
so that the blade will be suspended a few
inches off the ground when lowered.
2. Lower the blade until its weight is supported
by the jack stands.
3. Activate the control FLOAT function and
manually collapse the lift ram all the way. (Not
required for HT Series™ blades.) Turn the
control OFF.
NOTE: Loosen the fill plug slowly to relieve
any pressure in the reservoir.
4. Remove the drain plug in the bottom of the
hydraulic reservoir for straight blades, or the
drain cap located on the fitting side of the
hydraulic unit for XtremeV™, XV2™, EZ‑V
®
,
and XLS™ blades. (See illustrations on
previous pages.)
5. Completely drain the reservoir and replace the
drain plug/cap.
