4. 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 NTA907 or NTA3007 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 (Option)
Refer to Figure 12
This is a single hydraulic line, connected to the tractor
“Brake” outlet.
The factory default connector is a
3 ⁄
4
inch 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:
3 ⁄
4
inch male ORB (O-Ring Boss), or
3 ⁄
4
inch 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.
1. Mate lighting connector to tractor outlet.
2. Mate monitor connector to tractor harness.
3. Mate any optional or after-market electrical
connectors.
Make connections prior to drill movement. Some drill
hydraulic circuits are under monitor control.
