17. Connect the “Provision” or “Supply” line. This line is
Red-coded.
The Provision line charges a reservoir tank on the
drill. The Brake line operates a valve system which
meters tank air to the master cylinder on the drill.
Braking Hazard:
Do not use the NTA607 with a “single-line” air brake system.
This drill 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 drill brakes.
Roll-Away Hazard:
When unhitching, disconnect the red (control) line first. This
sets the brakes on the drill.
Hydraulic Brake Hook-up
Refer to Figure 12
This is a single hydraulic line, connected to the tractor
“Brake” outlet.
The factory default connector is a 19 mm (
3 ⁄
4
in) 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 (
3 ⁄
4
in) male ORB (O-Ring Boss), or
19 mm (
3 ⁄
4
in) female JIC (Joint Industry Conference,
37
° flare).
Electrical Hook-up
Refer to Figure 13
Make sure tractor is shut down with accessory power off
before making connections.
18. Mate lighting connector to tractor outlet.
19. Mate monitor connector to tractor harness.
20. Mate any optional or after-market electrical
connectors.
Make connections prior to drill movement. Some drill
hydraulic circuits are under monitor control.
