ENGLISH 13
• An often fall out of the motor could be a too small diameter of the cable which on a long dis-
tance of cable will deduct the power of the vacuum pump. The cable diameter should be at
least 1,5mm². Avoid pinching or kinking the supply cord and hose.
•
Check the water level in the water separator and empty it if necessary.
• Wall outlet should be suitable for the power cord plug.
If any adaption is necessary, in accordance with local voltage requirements, have the plug
replaced by a qualified electrician.
Before carrying out the electric connection, make sure that the main switch is OFF,
position “0”. Never stop the vacuum pump by unplugging it!
3.2 Motor protection switch
In the motor there is a motor protection switch built in. If that switch is getting in function for any
reason (over load, low-tension voltage, over heating caused by malfunctions) and cuts off pow-
er, you can start the machine again by pressing the release knob (previously wait about 5
minutes).
If this release knob cannot be fixed immediately you have to wait until the motor has cooled
down.
If the motor protection switch is getting often in function a specialist has to check it.
3.3 Pressure gauge
 Regularly check the pressure gauge while you are working!
more than -0,8 bar: vacuum pressure is adequate
less than -0,8 bar: vacuum pressure is inadequate
Interrupt your work, as soon as the vacuum pressure is no longer adequate.
Check the system for leakage or kinks in the hose.
Let the caused damages be repaired by the manufacturer or an authorized service center (see
6.).
3.4 Water separator
 Regularly check the water level in the water separator!
Built-in safety valve protects the pump from water being drawn into the pump when the water
container is full and the vacuum pressure will drop.
To empty the water separator see 5.
3.5 Switch off
• Turn off the main switch (OFF).
• Pull out the supply cord plug from the power outlet.
4 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: horizontal Ø 150 mm
vertical Ø 250 mm
