1. If using the anchor base plate, set an anchor suitable
for the applicable base material at a distance (ideally)
of 267 mm (10 ½ ") from the center of the hole to be
drilled or, if using the combination base plate, at a
distance of 292 mm (11 ½ ") from the hole center.
2. Screw the clamping spindle into the anchor.
3. Place the drill stand base plate over the spindle and
align it.
4. Screw the clamping nut onto the spindle but do not
tighten it.
5. Level the base plate by turning the four leveling
screws. Take care to ensure that the leveling screws
make firm contact with the underlying surface.
6. Use a suitable open-end wrench to tighten the
clamping nut on the clamping spindle.
7. Make sure that the drilling system is secured reliably.
6.1.4 Fitting the hand wheel 7
The hand wheel can be fitted on either side of the drill
stand.
1. Fit the hand wheel onto the axle.
2. Secure the hand wheel.
6.1.5 Mounting the machine on the drill
stand 8 9 10 11 12 13
CAUTION
The locking pins on the drill stand must be in the open
position and the carriage should be at the top of the
column. The carriage must be locked in position.
1. Use the hand wheel to release the locking pin (turn
counterclockwise) and then pull the locking pin out.
2. Engage the interface plate on the machine with the
hooks on the drill stand.
3. Push the locking pin in and use the hand wheel to
tighten it securely (turn clockwise).
4. Insert the switch locking device in the grip. The
switch locking device can be used to lock the on/off
switch in the "on" position for sustained operation.
5. Close the water valve on the side handle.
6. Connect the water supply
6.1.6 Removing the machine from the drill stand
DANGER
The machine must be disconnected from the electric
supply.
The carriage must be locked in position.
1. Close the water valve on the side handle.
2. Disconnect the water supply.
3. Remove the switch locking device from the grip.
4. Use the hand wheel to release the locking pin (turn
counterclockwise).
5. Pull the locking pin out of the slot.
6. Pivot the machine away from the drill stand.
6.1.7 Fastening the drill stand by vacuum 14
DANGER
Overhead drilling with the machine secured only by
the vacuum base plate is not permissible.
CAUTION
Make yourself familiar with information contained in
the operating instructions for the vacuum pump and
follow these instructions before using it.
WARNING
Before beginning drilling and during operation it must
be ensured that the pressure gauge indicator remains
within the green area.
VACUUM
VACUUM
NOTE
Optional when using the drill stand with the anchor base
plate: Screw the anchor base plate onto the vacuum base
plate.
NOTE
Make sure that the anchor base plate lies flat against the
vacuum base plate and that the two plates are securely
connected. Make sure that the core bit selected for use
will not damage the vacuum base plate.
1. Turn (retract) the 4 leveling screws until they project
approx. 5 mm beneath the combination base plate
or, respectively, the vacuum base plate.
2. Connect the vacuum pump to the vacuum connector
on the combination base plate or vacuum base plate.
3. Locate the center point of the hole to be drilled.
4. Draw a line approximately 800 mm in length from
the center of the hole to be drilled towards where
the drill stand is to be positioned.
5. Make a mark on the line at a distance of 292 mm
(11½") from the center of the hole to be drilled.
6. Switch on the vacuum pump and press the vacuum
release valve.
7. Bring the mark on the combination base plate or
vacuum base plate into alignment with the line.
8. Once the drill stand has been positioned correctly,
release the vacuum release valve and press the base
plate against the work surface.
9. Level and steady the combination base plate or
vacuum base plate by turning the 4 leveling screws.
10. An additional means of securing the drilling system
must be provided when drilling horizontally (e.g. a
chain attached to an anchor, etc.).
11. Make sure that the drilling system is secured reliably.
