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

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
Refer to
1. Install a Female Swivel x Male O-Ring Elbow Fitting
onto each Drawbar Bulkhead.
2. Install Female Coupler onto each Elbow Fitting
Figure 2-9: Female Coupler Installation
NOTE
The Magnet provided is used to prevent hoses from
dragging with drawbar extended.
3.
Telescoping Drawbars:
Assemble the Magnet,
Hose Clamp, Handle and Hardware to the Drawbar
Hoses halfway between the Drawbar A-Frame and
Hose Support.
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 hands, to search for
suspected leaks. Wear protective gloves &
safety glasses or goggles when working with
hydraulic systems.
The Wing Frames depend upon flow restrictors in
the hydraulic manifold to prevent uncontrolled
falling when folding or unfolding. Removal or
improper settings of these restrictors can cause
the machine to fold or unfold improperly and
result in serious machine damage.
