Incorrect lifting of loads
Falling loads may cause serious injuries and even death.
• Stand clear of suspended loads and do not step into their swiv-
eling range.
• Never move loads without supervision.
• Do not leave suspended loads unattended.
2.12.2 Protection during commissioning and operation
Falling or violently ejected components
Falling and violently ejected components can cause serious injuries
and even death.
• Take appropriate protective measures to secure the danger zone.
• Never step into the danger zone during operation.
2.12.3 Protection against dangerous movements
Unexpected movements
Residual energy in the system may cause serious injuries while
working with the product.
• Switch off the energy supply, ensure that no residual energy re-
mains and secure against inadvertent reactivation.
• Never rely solely on the response of the monitoring function to
avert danger. Until the installed monitors become effective, it
must be assumed that the drive movement is faulty, with its ac-
tion being dependent on the control unit and the current oper-
ating condition of the drive. Perform maintenance work, modi-
fications, and attachments outside the danger zone defined by
the movement range.
• To avoid accidents and/or material damage, human access to
the movement range of the machine must be restricted. Limit/
prevent accidental access for people in this area due through
technical safety measures. The protective cover and protective
fence must be rigid enough to withstand the maximum possible
movement energy. EMERGENCY STOP switches must be easily
and quickly accessible. Before starting up the machine or auto-
mated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.

•Switch off power supply before assembly and installation.
•Make sure that no residual energy remains in the system.
NOTICE
Observe the requirements for the pressure supply,
Technical data [}12].
The pressure supply with compressed air or cooling lubricant is
provided by the machine spindle.

5 Operation
NOTE
Using the fitting bores and threads (6), auxiliary means (e.g. for
positioning of the workpiece) can be fastened.
Hold workpiece ØPlace the GSW-M with the rubber friction ring (1) on the workpiece.
ØLower the GSW-M further in direction of the workpiece (20
mm) until the magnet (2) is flush with the rubber friction ring
(1) on the workpiece. To achive this, the spring force of the
spring (3) must be overcome.
✓The workpiece is now held magnetically.
Note: The GSW-M has a compensating stroke of 9 mm to
protect the machine and the workpiece, thereby the spring
(5) is compressed.
ØLift GSW-M together with the workpiece.
✓The spring (5) relaxes again by the compensationg stroke.
Release workpiece ØSet down the GSW-M with the workpiece.
✓The compensation stroke of 9 mm can be used here.
ØApply compressed air or cooling lubricant to the mount (4) to
loosen the workpiece.
✓While this is happening, the GSW-M continuously dscharges
compressed air or cooling lubricant through the outlet opening.
ØLift GSW-M
✓Due to the excess pressure in the interior of the GSW-M, the
workpiece is held in a defined position via the rubber friction
ring (1) an its storage position and separated from the mag-
net (2) when picking up by the GSW-M.
