Connecting The Water Supply - Hilti DD 200 Mode D'emploi

must be increased by fitting the spacer when diamond
core bits with a diameter greater than 300 mm are to be
used. The hole center indicator cannot be used in con-
junction with the spacer.
These instructions presume that the drive unit is not
already fitted.
1. Lock the carriage in position on the column (activate
the carriage locking mechanism). The carriage is
locked when the locking bolt is engaged. Check this
by turning the hand wheel at the locking mechanism.
No movement of the carriage is possible when in this
position (locked).
2. Release the drive unit locking bolt.
3. Pull out the locking bolt.
4. Fit the spacer onto the carriage.
5. Push the locking bolt into the carriage as far as it will
go.
6. Tighten the locking bolt securely.
6.3.8 Mounting the drive unit on the drill stand
-NOTE-
Ensure that the drive unit is disconnected from the elec-
tric supply.
1. Lock the carriage in position on the column (activate
the carriage locking mechanism). The carriage is
locked when the locking bolt is engaged. Check this
by turning the hand wheel at the locking mechanism.
No movement of the carriage is possible when in this
position (locked).
2. Pull out the drive unit locking bolt.
3. Fit the drive unit onto the carriage or spacer.
4. Push the locking bolt into the carriage or spacer as
far as it will go.
5. Tighten the locking bolt securely.
6. Clip the supply cord into the supply cord guide on the
carriage cover.
7. Check that the drive unit is mounted securely.

6.3.9 Connecting the water supply

1. Close the water flow regulator on the drive unit.
2. Connect the water supply hose to the hose connec-
tor.
-NOTE-
A water flow indicator (accessory) can be connected
between the water supply hose and the hose connector
on the drive unit.
-CAUTION-
Check the hoses for damage at regular intervals and
ensure that the maximum permissible water supply pres-
sure of 6 bar is not exceeded.

6.3.10 Fitting the water collector system
(accessory)
-NOTE-
Use of the water collection system permits water to be
drained away from the core bit thus avoiding soiling the
surrounding area. We recommend use of the water col-
lector system with core bits of up to 250 mm. diameter.
Best results are achieved in conjunction with a wet-type
vacuum cleaner.
Use of the water collection system in conjunction with
a wet-type vacuum cleaner is mandatory for overhead
drilling. The drill stand must be set up at 90° to the ceiling.
The water collector seal must be of a size suitable for
the core bit diameter used.
1. Release the screw on the drill stand (at the front low-
er end of the column).
2. Slide the water collector holder into place behind the
screw from below.
3. Tighten the screw securely.
4. Fit the water collector between the two moveable arms
of the water collector holder.
5. Secure the water collector by way of the two screws
on the water collector holder.
6. Connect the water collector to a wet-type vacuum
cleaner. Alternatively, the water can be allowed to flow
away through a length of hose attached to the con-
nector.
6.3.11 Adjusting the depth gauge (accessory)
1. Turn the hand wheel until the core bit contacts the
material in which the hole is to be drilled.
2. Set the desired drilling depth by adjusting the distance
between the carriage and the depth gauge.
3. Secure the depth gauge by tightening the clamping
screw.
