Fastening possibilities (Fig. B)
a) Dowel fastening on concrete or brickwork (picture B-1)
Î
Measure and drill a mounting hole for the dowel fastening.
Diameter in mm
Depth in mm
Concrete (Item no. FF35120)
15 mm
65mm
Brickwork (Item no. FF35121)
20mm 85mm
Î
Carefully clean the drill dust from the borehole.
Î
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.
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.
Î
Attach the base plate
(8)
and fasten with the grommet and the wing nut.
b) Bracing with the quick clamp column (Item no. FF35015 picture B-2)
Î
Align the drill rig and attach the quick clamp column to the base plate of the drill rig.
Î
Extend the quick clamp column and clamp the drill rig.
Minimum room height:
approx. 1.7 m
Maximum room height:
approx. 3.0 m
Information:
In order to avoid damage to the ceilings or walls by the quick clamp column,
place a piece of wood or similar between the end of the column and the ceiling to distribute
the contact pressure over a larger area.
Please read and be sure to understand the supplied quick clamp column instruction
manual.
c) Vacuum set fastening (Item no. FF35710= 131 DWS; FF35740= 202 DWS; picture B-3)
with vacuum pump (Item no. FF35200)
Î
Place the cellular rubber ring in the groove incorporated in the base plate
(8)
of the drill rig.
Î
Connect the vacuum set to the vacuum pump by means of the quick coupling.
Î
Connect the vacuum pump to the mains supply and switch on.
Î
Position the base plate
(8)
and insert the vacuum connecting piece with 3-way ball valve in
the elongated hole of the base plate.
Î
Press firmly on the hand toggle of the ball valve and activate while simultaneously pressing
the base plate onto the ground.
Operate the ventilation button
(9)
in the foot plate 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.
In the event of a power failure, the safety tank on the RODIA-VAC vacuum pump ensures that the
equipment remains firmly attached to the ground for approx. 1 2 minutes. This time period,
however, is strongly dependent on the impermeability of the system and the condition of the
ground.
Check the negative pressure constantly during drilling work. The pressure must not fall below
0.8
bars
.
