Hydraulic System
The Pulverizer is equipped with a hydraulic system to
raise and lower the
unit.
Escaping hydraulic fluid can cause serious
personnel injury. Relieve system pressure before
repairing, adjusting, or disconnecting. Wear
proper hand and eye protection when searching
for leaks. Use cardboard instead of hands (See
Figure 3-5.) Keep all components (cylinders,
hoses, fittings, etc.) in good repair.
Figure 3-5: Hydraulic Leak Detection
If the hydraulic system is not filled with oil it should be
purged of air before transporting and field operations.
Carefully hitch the Pulverizer to the tractor or other
implement and connect the hydraulic hoses. Check to
make sure the tractor hydraulic reservoir is full of the
manufacturer's recommended oil.
Be sure the system is fully charged with hydraulic oil
before attempting to raise and lower the unit. The system
needs to be charged with oil initially and any time the
system has been opened for repair such as cylinder,
hose, or fitting replacement/repair
Hydraulic Lift Circuit
The Pulverizer is equipped with a hydraulic lift circuit that
raises/lowers the machine. The tractor should be stopped
and not moving on a level area.
