Hydraulic Installation
IMPORTANT
Unfold and lower the unit to the ground and relieve
system pressure before attempting to repair, adjust,
or disconnect components.
WARNING
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. Wear protective gloves &
safety glasses or goggles when working with
hydraulic systems. Keep all components
(cylinders, hoses, fittings etc.) in good repair.
The Wing Float Pulverizer consists of a single circuit that
folds and lifts the machine. The Hydraulic Circuit requires
approximately 4-1/2 to 6 gallons of hydraulic oil depending
on the Model.
Tightening Procedure For JIC 37° Swivel Female Nuts
1. Check flare and seat for defects.
2. Lubricate the connection.
3. Install hoses without twists.
4. Hand tighten until connection bottoms.
5. Using 2 wrenches to prevent twisting, rotate the
swivel nut 2 wrench flats (1/3 turn).
6. For reassembly, follow the same procedure but
tighten only 1 wrench flat (1/6 turn).
Tightening Procedure For Swivel O-Ring Fittings
1. Lubricate O-Ring and install the fitting until the metal
washer which backs up the O-Ring contacts the face
of the boss.
2. Orient the fitting by turning counterclockwise up to 1
turn.
3. Tighten the lock nut using 50-60 foot pounds torque.
( See "Hydraulic Fitting Torque Specifications" on
page 4-2.)
Plumb the Hydraulic Circuit
CAUTION
Restrictors are installed in both the rod and
base end of wing fold cylinders to prevent
uncontrolled dropping of wings. Removal of
these restrictors, or improper installation can
result in serious damage to the implement.
