20. Connect the “Provision” or “Supply” line. This line is
Red-coded.
The Provision line charges a reservoir tank on the
implement. The Brake line operates a valve system
which meters tank air to the master cylinder on the
implement.
Braking Hazard:
Do not use the 8315/8318/8321/8324DVN with a “single-line”
air brake system. This Discovator is designed for transport
speeds that require an air brake system to be “dual-line”. A
single-line tractor system cannot charge the tank that powers
the Discovator brakes.
Roll-Away Hazard:
When unhitching, disconnect the red (control) line first. This
sets the brakes on the implement.
Hydraulic Brake Hook-up
Refer to Figure 13
This is a single hydraulic line, connected to the tractor
“Brake” outlet.
The factory default connector is a 19 mm poppet-style
QD (Quick Disconnect). If this is incompatible with your
tractor, it may be replaced by a connector that mates to,
or can be adapted to:
19 mm male ORB (O-Ring Boss), or
19 mm female JIC (Joint Industry Conference, 37
°
flare).
