6.1.1 Fixing onto the wall
3 If fixing onto the wall, an external spirit level
must be used to adjust the perpendicularity of the
drill stand with the drillhole of the diamond drill
core bit. This adjustment cannot be made using the
integrated spirit level (7) on the drill stand.
6.1.2 Installing the drill stand with
vacuum kit (accessory)
If it is not possible to install the drill stand with the
anchor fixing, the drill stand can be fixed to the
floor using a vacuum kit (order on request). The
installation of the vacuum kit is described in the
relevant installation instructions.
6.2 Adjusting the tilt at the drill
stand
The drill stand can be continuously adjusted up to
a tilt of 45°.
•
18 Undo the top cheese head screw (3) and
the two bottom cheese head screws (2) of the
angle adjustment, it may be necessary to hold
the nuts on the opposite side to prevent them
from moving.
•
18 Set the drill stand column (1) to the required
drilling angle.
•
18 Re-tighten the two bottom cheese head
screws (2) and the top cheese head screw (3).
NOTE
18 The drill stand may not be used again until all
three cheese head screws (2 and 3) have been
screwed tight.
6.3 Fixing the wet diamond drill to
the drill stand
•

Use the clamping lever (1) to lock the spindle
head (2).
•
19 Unscrew the tapered shaft (2) and pull it out
of the spindle head (4) up to the limit stop.
•
19 Hook the machine collar (3) from above into
the holder of the spindle head (1) and push the
machine collar (3) downwards.
•
19 Push the tapered shaft (2) through the
machine collar (3) and tighten using an open-
ended spanner.
NOTE
Never use the feed crank handle to tighten the
tapered shaft; it could be damaged by excessive
torque.
•
20 Undo the two cheese head screw (3) in the
machine collar (2).
•
20 Insert the drill (4) from above into the
machine collar (2) of the drill stand up to the
limit stop.

•
Repeat in the reverse order to remove the
diamond drill from the drill stand.
6.4 Set guide clearance on spindle
head
The spindle head must run without any clearance; it
is adjusted using two hexagon head socket screws.
•
21 Release the clamping lever (1).
•
21
Undo both lock nuts (2).
•
21 Adjust both hexagon socket head screws (3)
until the clearance is removed.
•
21
Tighten both lock nuts (2).
•
21 Turn the capstan handle (4) in both
directions and check whether the spindle
head (5) moves without clearance.
NOTE
The clearance is set correctly if, when the
clamping lever is released, the spindle head with
the mounted wet diamond drill does not move
downward under its own weight or if so, moves
very slowly.
6.5 Switching on the wet diamond
drill and drilling
•
Before starting up the wet diamond drill, check
all the points described in the “Before starting
work” chapter (see page 39 ff.).
•
Select the core drill bit and fit (see “Fitting or
changing the wet diamond core drill bit” on page
40).
NOTE
Changing gear while the machine is running can
cause damage to the drill.
Wait for the machine to completely stop.
