5.1.2 Installing the hand wheel
Note
You can install the hand wheel on the right or left side of the carriage on two different shafts.
If you install the hand wheel on the top shaft, the shaft acts directly on the drive of the carriage.
If you install the hand wheel on the bottom shaft, the shaft acts through reduction gearing on the drive
of the carriage.
1. Install the hand wheel on the shaft of your choice on the appropriate side.
2. Secure the hand wheel with the screw.
5.1.3 Securing the drill stand with an anchor
WARNING
Risk of injury The tool may become detached and cause damage if the wrong anchor is used.
▶ Use an anchor suitable for the base material on which you are working and observe the anchor
manufacturer's instructions. Please contact Hilti Technical Service if you have any questions about
secure fastening.
1. Set the anchor for the base plate 330 mm (13 inch) from the hole center.
Note
If you work with a spacer, increase the distance accordingly.
2. Screw the clamping spindle into the anchor.
3. Slip the drill stand over the spindle and align it.
4. Screw the clamping nut on to the spindle but do not tighten it.
5. Use the leveling screws to level the base plate.
6. Use a suitable open-end wrench to tighten the clamping nut on the clamping spindle.
7. Check that the drill stand is secure.
5.1.4 Securing the drill stand by vacuum
DANGER
Risk of injury Hazard presented by a falling diamond core drilling machine.
▶ Fastening the drill stand to the ceiling only by means of the vacuum securing method is not
permissible. A heavy structural support or a threaded spindle, for example, can serve as an
additional means of fastening.
WARNING
Risk of injury Pressure check
▶ Before beginning drilling and during operation, it must be ensured that the pressure gage indicator
remains within the green area.
Note
In order to use the drill stand with anchor base plate, establish a secure, flat-on-flat connection between
vacuum base plate and anchor base plate. Screw the anchor base plate securely to the vacuum base
plate. Make sure that the core bit selected for use will not damage the vacuum base plate.
If you are going to drill horizontally, use additional means of securing the diamond core drilling machine
(e. g. chain secured to anchor).
Read the operating instructions for the vacuum pump.
Note
Before positioning the drill stand, check that you have sufficient space for assembly and operation.
1. Turn all the leveling screws until they project approx. 5 mm underneath the vacuum base plate.
