• Install the provided protective product in the danger zone
before switching on the product.
• Remove the energy supplies before installation, modification,
maintenance, or adjustment work. Ensure there is no residual
energy in the system.
• Do not move parts by hand while the energy supply is connected.
• Do not reach into the movement area of the product during
operation.
2.11.1 Protection during handling and assembly

and cause serious injuries and considerable material damage.
• Have all work carried out by appropriately qualified personnel.
• For all work, secure the product against accidental operation.
• Observe the relevant accident prevention rules.
• Use suitable assembly and transport equipment and take
precautions to prevent jamming and crushing.

Basic safety notes
Incorrect lifting of loads
Falling loads may cause serious injuries and even death.
• Stand clear of suspended loads and do not step into their
swiveling range.
• Never move loads without supervision.
• Do not leave suspended loads unattended.
2.11.2 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.
2.11.3 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
remains 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
action being dependent on the control unit and the current
operating condition of the drive. Perform maintenance work,
modifications, 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
automated system, check that the EMERGENCY STOP system is
working. Prevent operation of the machine if this protective
equipment does not function correctly.

5 Operation
NOTE
Using the fitting bores and threads (6), auxiliary means (e.g. for
positioning of the workpiece) can be fastened.
Hold workpiece 1. Place the GSW-M with the rubber friction ring (1) on the
workpiece.
2. Lower 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.
3. Lift GSW-M together with the workpiece.
✓The spring (5) relaxes again by the compensationg stroke.
Release workpiece 1. Set down the GSW-M with the workpiece.
✓The compensation stroke of 9 mm can be used here.
2. Apply 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.

Operation
3. Lift 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 magnet (2) when picking up by the GSW-M.
