HYDRAULIC SYSTEM
The hydraulic unit's valve manifold includes relief
valves to prevent damage to the blade or vehicle
if either end of the blade hits an obstacle. The
valves are preset at the factory and do not need any
adjustments unless the valve manifold is serviced.
When force against the blade causes the pressure
in an extended ram to exceed the set limits, the relief
valve opens, allowing
fl uid to escape, and the ram
retracts.
For hydraulic fl uid type and fi lling instructions, see
Hydraulic System, Annual Fluid Change, in the
Maintenance Section of this manual.
