Adjusting The Depth Gauge - Hilti DD 130 Manual De Instrucciones

4. Connect a wet-type vacuum cleaner to the front of the
water collection system. Alternatively, the water can
be allowed to flow away through a length of hose
attached to the connector (not permissible for over-
head drilling).

6.6.2 Adjusting the depth gauge

1. Set the depth gauge to the desired depth.
2. Use the clamping screw to secure the depth gauge.
6.7 Using the drill stand
6.7.1 Fastening the drill stand with an anchor
-WARNING-
Use an anchor suitable for the material on which you
are working and observe the anchor manufacturer's
instructions.
-NOTE-
Hilti M12 metal expansion anchors are usually suitable
for fastening diamond core drilling equipment to uncracked
concrete. Under certain conditions it may be necessary
to use an alternative fastening method. Please contact
Hilti Technical Service if you have any questions about
secure fastening.
1. Set the anchor of a type suitable for the material on
which you are working at a distance of 200 mm (ide-
ally) from the center of the point where the hole is to
be drilled.
2. Screw the quick-release spindle into the anchor.
3. Place the drill stand over the quick-release spindle
and position it correctly with the aid of the hole cen-
ter indicator.
4. Screw the nut onto the quick-release spindle but do
not tighten it fully.
5. Use the four leveling screws to level the base plate.
Check that all four leveling screws are in contact with
the surface. The bubble level on the base plate serves
as a leveling aid.
6. Lock the leveling screws by tightening the lock nuts.
7. Use an open-end wrench to tighten the lock nuts.
8. Check to ensure that the drill stand is fastened securely.
6.7.2 Securing the drill stand with the vacuum pad
A vacuum release valve is incorporated in the baseplate
grip.

Overhead drilling with the drill stand attached only by
vacuum is not permissible.
1. Unscrew the four levelling screws until they project
approx. 5 mm beneath the baseplate.
2. Connect the hose between the vacuum connector on
the baseplate and the vacuum pump.
3. Switch on the vacuum pump and extend the hole
centre indicator. While pressing the vacuum release
valve and observing the hole centre indicator, bring
the baseplate into the desired position. When posi-
tioned correctly, press the baseplate against the work
surface and remove your finger from the vacuum
release valve. Before beginning drilling and during
operation, it must be ensured that the pressure gauge
pointer remains within the green area.
4. The four levelling screws should then be used to lev-
el the baseplate. The spirit level on the baseplate serves
as a levelling aid.
5. Tighten the lock nuts to prevent further movement of
the levelling screws.
6. An additional means of securing the drill stand must
be employed when drilling horizontally (e.g. a chain
attached to an anchor, ...)
7. Check to ensure that the drill stand is fastened secure-
ly.
6.7.3 Securing the drill stand with a quick-release
brace (e.g. between floor and ceiling)
1. Extend the hole centre indicator and then use it as an
aid to bring the drill stand into alignment with the cen-
tre point of the hole to be cored.
2. Position the end of the quick-release brace carefully
in the inner oval of the baseplate (not on the level indi-
cator or pressure gauge).
3. Secure the baseplate by applying slight pressure with
the quick-release brace.
4. The four levelling screws should then be used to lev-
el the baseplate. The spirit level on the baseplate serves
as a levelling aid.
5. Tighten the lock nuts to prevent further movement of
the levelling screws.
6. Tighten the quick-release brace securely.
7. Check to ensure that the drill stand is fastened secure-
ly.
6.8 Water collection system for use with the drill stand
Use of the water collection system permits water to be
drained away from the core bit thus avoiding soiling the
surrounding area. Best results are achieved in conjunc-
tion 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 work
surface.
The water collector sleeve and seal must be of a size
suitable for the core bit diameter used.
1. Slacken the column adjusting lever until the locating
lugs are disengaged.
2. Tilt the frame.
