Purging the Hydraulic System
IMPORTANT
Unfold and lower the unit to the ground and relieve
system pressure before attempting to repair, adjust,
or disconnect components.
WARNING

Figure 2-16: Hydraulic Leak Detection
The hydraulic system is not filled with oil and should be
purged of air before transporting and field operations.
Carefully hitch the Pulverizer to the tractor and connect the
Hydraulic Hoses. Check to make sure the tractor hydraulic
reservoir is full of the manufacturer’s recommended oil.
Block each Fold Cylinder Rod End up to allow for rod
movement. Completely extend and retract Fold and Lift
Cylinders. Recheck tractor oil reservoir. Extend and retract
the Cylinders completely 5-6 times to purge air from the
Hydraulic Circuit. Do not loosen hoses/fittings. Recheck
tractor reservoir oil level. Hydraulic Circuit requires
approximately 4-1/2 to 6 gallons of hydraulic oil depending
on the Model. After the Hydraulic Circuit has been purged,
leave the Wing Cylinders extended for Wing Installation.
Escaping fluid under pressure can be nearly
invisible and have enough force to penetrate
the skin causing serious injury. Use a piece of
cardboard, rather than your hands, to search
for suspected leaks. (
See Figure 2-16. ) Wear
protective gloves & safety glasses or goggles
when working with hydraulic systems. Keep all
components (cylinders, hoses, fittings etc.) in
good repair.
