Before installing the auto-feed unit, check the following points:
• The carriage of the drill stand has a mounting interface for a Hilti auto-feed unit.
• The hand wheel has been removed from the carriage of the drill stand.
The adapter for the auto-feed unit is on the side of the carriage. The auto-feed unit can be installed in
any of 5 mounting positions. The 5 mounting positions of the auto-feed unit are keyed in 30° steps
between 0° and 120°. The auto-feed unit can be secured with the securing screw only at these positions.
1. Lock the carriage with the carriage lock.
2. Set the auto-feed unit on the mounting adapter of the drill stand.
3. Turn the auto-feed unit until the square shaft engages in the square-shaft adapter on the carriage.
4. Hold the auto-feed unit and disengage the carriage lock.
5. Position the auto-feed unit at one of the 5 keyed mounting positions.
▶ The auto-feed unit engages correctly at the keyed position.
▶ The EMERGENCY STOP switch is freely accessible.
▶ The auto-feed unit does not obstruct the planned drilling operation.
6. Tighten the securing screw by hand.
7. Connect the cooling water connector of the auto-feed unit to the water connection of the diamond core
drilling machine.
8. Connect the electric supply cord and the water supply hose.
▶ The water valve switches with an audible click.
9. Check that the auto-feed unit and the cooling water supply are correctly installed and connected.
5.2 Pairing auto-feed unit and diamond core drilling machine
5.2.1 Establishing a new Bluetooth connection (pairing)
Before you can use the auto-feed unit with a diamond core drilling machine as a drilling system, you have
to pair the two system products via Bluetooth. This pairing remains saved as a successful pairing operation
until you pair another auto-feed unit to the diamond core drilling machine, overwriting the existing pairing.
Pair the auto-feed unit only to a diamond core drilling machine recommended by Hilti. The supply
voltage must match the ratings stated on the rating plate of the diamond core drilling machine.
