3.2 Start of operation
Positionierung:
Please pay attention to the position of the ring bolts (14)! Ring bolts must not
overlap the lower edge of the base plate!
 Measure borehole and mark the centre. See technical data for extent of dowel depth!
 Adjust and fasten base plate.
The respective optimum fastening possibility depends on the building site conditions (see
fastening possibilities, item 3.3)
You can achieve the final fine alignment or adjustment of the drill rig by tightening the four ring
bolts (14).
Every time before start of operation make sure that the drill rig is firmly
fastened and not able to shake!
3.3 Fastening possibilities
Dowel fastening on concrete or brickwork

Measure and drill a mounting hole for the dowel fastening. See technical data for extent
of dowel depth!
Diameter in mm Depth in mm
Concrete (item no. FF35120) 15 mm 65mm
Brickwork (Art. Nr. FF35121) 20mm 85mm
 Carefully clean the drill dust from the borehole.
 Apply the concrete dowel with expansion wedge or brickwork dowel (can be re-used up to 5
times)
Concrete set: Turn the diamond knurl threaded bar into the dowel, attach the drill rig and
fasten using the U-washer and nut.
Brickwork set: Screw the diamond knurl threaded bar with the grommet and mounted nut
into the armature. Tighten the nut using an open-ended spanner. Attach the drill rig and
fasten using the U-washer and nut.
Vacuum set fastening with vacuum pump (only with base plate Combi!)
 Place the cellular rubber ring in the groove incorporated in the base plate Combi (1) of the
drill rig.
 Connect the vacuum set to the vacuum pump by means of the quick coupling.
 Connect the vacuum pump to the mains supply and switch on.
 Position the base plate Combi (1) and insert the vacuum connecting piece with 3-way ball
valve in the elongated hole of the base plate Combi.
 Press firmly on the hand toggle of the ball valve and activate while simultaneously pressing
the base plate Combi (1) onto the ground.
Operate the ventilation button (4) in the foot plate Combi to re-position the drill rig on the
ground.
Max. drill range with vacuum technique:
horizontal Ø 150 mm
vertical Ø 250 mm
The vacuum technique is only to be used on smooth ground, as an adequate vacuum can
only be produced here. Never suck in on plaster
. The drill rig could break away from
the wall.
