Fastening The Drill Stand With The Vacuum Base Plate (Accessory) - Hilti DD 200 Manual De Instrucciones

hole center indicator cannot be used to position the
drill stand if the spacer (accessory) is fitted).
4. Screw the clamping nut onto the spindle but do not
tighten it fully.
5. Use the 3 leveling screws to level the base plate. The
2 leveling indicators on the carriage serve as an aid.
Check that all leveling screws are in firm contact with
the surface.

6. Use a 27 mm open-end wrench to tighten the clamp-
ing nut on the spindle. Alternatively, the leveling screw
at the rear can be tightened. The strut can be pivoted
out of the way to provide better access.
7. Check to ensure that the drill stand is fastened securely.

-CAUTION-
Check the surface on which the vacuum base plate is to
be mounted. An uneven, rough surface can significant-
ly reduce the effectiveness of the vacuum fastening sys-
tem. Coatings or laminated surfaces may be pulled away
while working with the vacuum base plate.
-CAUTION-
Suitable for use only with core bits of up to 300 mm
diameter and without use of a spacer.
-NOTE-
The hand grip on the vacuum base plate is equipped
with a vacuum valve which can be used to release the
vacuum.
1. Turn the four leveling screws back until they project
approx. 5 mm beneath the vacuum base plate.
2. Connect the hose between the vacuum base plate and
the vacuum pump.
3. Position the drill stand on the vacuum base plate.
4. Fit the screw and washer provided.
5. Mark the center point of the hole to be drilled.
6. Draw a line approximately 800 mm in length from
the center mark toward the approx. position at which
the drill stand is to be secured.
7. Make a mark on the 800 mm line at a distance of
165 mm (6 ⁄ ") from the hole center mark.

8. Bring the marks on the vacuum base plate into align-
ment with the 800 mm line.

-CAUTION-
The drill stand must be secured
additionally with a chain when
drilling horizontally.
Overhead drilling with the drill
stand secured only by the vacu-
um base plate is not permissible.
9. Position the center of the front edge of the vacuum
base plate on the line at the 165 mm (6
-NOTE- Before using the vacuum pump, make your-
self familiar with the information contained in its
operating instructions and observe these instruc-
tions.
10. Switch on the vacuum pump and press the vacuum
release valve.
11. Once the drill stand has been positioned correctly,
remove your finger from the vacuum release valve
and press the base plate against the work surface.
-CAUTION- Ensure that the pressure gauge pointer
remains within the green area before beginning drilling
and during the drilling operation.
12. Use the four leveling screws to level the vacuum
base plate. The 2 built-in level indicators on the car-
riage serve as leveling aids. Note: Do not attempt to
level the anchor base plate on the vacuum base plate.
This is not permissible.
13. An additional means of securing the drill stand must
be employed when drilling horizontally (e.g. a chain
attached to an anchor, ...)
14. Check that the drill stand is fastened securely.
6.3.5 Adjusting the angle of the drill stand
(adjustable to max. 45°)
-CAUTION-
Take care to avoid pinching your fingers at the pivot.
Wear protective gloves.
1. Release the screw at the pivot at the lower end of the
column and at the strut at the top end.
2. Bring the column into the desired position. The angle
scale on the rear serves as an adjustment aid.
3. Retighten the two screws securely.
6.3.6 Using the column extension (accessory)
-CAUTION-
When starting a hole do not use core bits or extensions
with a total length of more than 650 mm.
1. Remove the end cap (with built-in end stop) from
the top end of the column and refit it to the end of
the column extension.
2. Fit the cylindrical section of the column extension
into the end of the column on the drill stand.
3. Secure the column extension by tightening the eccen-
tric locking bolt.
4. A depth gauge (accessory) may be fitted on the col-
umn as an additional end stop.
5. The end cap (with built-in end stop) must be refit-
ted to the column on the drill stand when the col-
umn extension is subsequently removed. The end
stop is a safety-relevant part and must always be
used.
