• Unscrew the rotary knob [9-1].
• Pull out the locking pin [9-2] and rotate
approx. 90°.
• Pull out the suction plate [9-3] while tur-
ning.

on the suction plate resting against the
clamping unit.
• Turn the locking pin [9-2] until it engages.
Please check.
• Clamp the rotary knob [9-1].
7 Operation
Warning
Risk of accident - read the following
prior to operation:
• The clamping unit should be attached se-
curely to the base and should not move.
• The indicator on the vacuum gauge [1-3]
must remain within the green sector at
all times. As soon as the indicator enters
the red sector, stop work immediately
and rectify the cause of the fault (see
"Chap. 13 Fault recti
fi
cation").
• Check the rubber cups on the suction plate
and the rubber seal on the base before
using the machine. Never work with a
damaged suction plate or rubber seal.
• Clamp workpieces so that the centre of
gravity is positioned over the suction
plate. The workpiece must protrude at
least 1 cm over the edge of the suction
plate on all sides.
• Do not push or pull on the clamped work-
piece with excessive force. There is a risk
that the workpiece will come loose from
the suction plate.
• Check whether the workpiece is seated
securely before starting work.
Working method
• Switch on the pump at the on/off switch
[1-2] (I = ON, 0 = OFF).
• Connect the vacuum hose to the connector
[3-2].
• Wait until the indicator on the vacuum
gauge [1-3] is within the green sector.
f
Clean the sealing lip on the suction plate
with a cotton cloth soaked in white spirit
so that no marks are left behind when the
workpiece is clamped.
• Place a workpiece on the suction plate.
The workpiece triggers the button valve
[10-1] and the suction force then secures
the workpiece.
• Check whether the workpiece is retained
securely.
• Perform the required work on the workpiece.
Removing the workpiece
Warning
Risk of accidents
• Always hold the workpiece with both
hands before actuating the foot valve.
• Make sure that the workpiece cannot fall
or tip after the foot valve is actuated.
• To release the workpiece, hold with both
hands and actuate the foot valve [2-5].
• Remove the workpiece.
• After using the pump, switch off at the
on/off switch [1-2] and remove the plug
from the power socket.

Service and maintenance
Warning
Risk of accident, electric shock
•
Always pull the plug out of the socket
before performing any type of work on
the machine.
•
All maintenance and repair work on the
pump must be carried out by an autho-
rised service workshop only.
To ensure constant air circulation, always
keep the ventilation openings [1-4] on the
pump container clean and free of blockages.
Clean the protective grille with a dust extrac-
tor. If damaged, have the protective grille re-
placed by an authorised service workshop.
Changing the rubber cup on the suction
plate (suction plate D215 only)
Replace the rubber cup immediately if faulty:
• Remove the screws [10-2].
• Remove the rubber cup.
• Place a new rubber cup in position.
• Secure the new rubber cup using the
screws [10-2].
