Vacuum set fastening with vacuum pump

 Place the cellular rubber ring in the groove incorporated in the base plate of the drill rig.
 Connect the vacuum set (No. FF35710 = 170 PRO-C / 131 DWS; No. FF35740 = 270 PRO-
C / 202 DWS) 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 and insert the vacuum connecting piece with 3-way ball valve in the
elongated hole of the base plate.
 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 in the foot plate to re-position the drill rig on the ground.
Max. drill range with vacuum technique:
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!
Remove the equipment from the wall immediately in the event of a power failure.
Danger due to the equipment falling off. Vacuum neutralized. Only work using slight
feed pressure.

Care, Maintenance and Cleaning

In order to keep your vacuum pump in good working conditions we recommend you to
perform periodical servicing operations. Before performing any maintenance opera-
tion, switch off the vacuum pump and make all air in the tank release.
• Do not use solvents, running water or pressure jet/spray systems - this may endanger the
electric safety.
• Keep the grip free from oil and grease.
• Regularly clean the ventilation slots with soft and dry brushes.
Vacuum pump:
All 3000 operating hours the cylinder heads have to be screwed off and the compressor tank
and the valves have to be checked. Complete valve plates or cylinder heads could be delivered
ex. Stock. Also the vacuum compressor block.
After 10000 operating hours the vacuum pump should be checked completely.
Tank:
By unsealed tube connections the pressure can go down. Frequently check the tube connec-
tions are necessary to provide pressure fall down.
Air suction filter (monthly cleaning):
The air suction filter should be cleaned frequently after a period of non-working or when used in
very dusty environment.
The filter part has to be re-newed after some time.
• Unscrew the screws and remove the motor casing by lifting.
• Take out the filter cover.
• Rinse the filtering component with water and soap, and make sure that it is totally dry before
to fit it again.
