Hydraulic Power Unit Fill
Procedure
Figure 37. External Fill – Backside View
Step 1 of the following fill procedure is intended
for a new plow with an empty hydraulic system.
Initial Plow Position: Start with the plow un-
attached from the vehicle and the lift cylinder
completely collapsed. The light tower will be tilted
forwarded.
1. Remove Fill Cap (30F) from Street Elbow
(30G) and fill with BOSS High Performance
Hydraulic Fluid. Continue to fill Street Elbow
(30G) until no more fluid will be accepted.
(Approx. 2 quarts.)
2. Attach the plow to the vehicle.
Note: If your plow is equipped with
SmartHitch2™ you must hydraulically power the
light tower up. Do not manually push the tower
up. Failure to hydraulically power the light tower
up will create an air pocket in the hydraulic
system. Oil will spill out of your internal filler cap.
