Operating the stapler
Regulating the stapler with the operating pressure
You can set the penetration depth of the stapler into the material by regulating the operating
pressure. At a higher operating pressure, the fasteners are driven deeper into the material; setting a
lower operating pressure reduces the penetration depth.
Set the operating pressure to achieve the required penetration depth. This has the
following benefits:
•You save energy (compressed air),
•you reduce the noise level, and
•you reduce the wear of the stapler.
Proceed as follows to set the operating pressure:
➢Adjust the pressure at the pressure valve of the compressor or compressed air system.
➢Observe the pressure reading.
Checking the penetration depth
➢Shoot a staple into a sample workpiece with the same characteristics as the processing
material.
➢Repeat these steps until you have set the required penetration depth.

Servicing the stapler
The stapler may only be serviced by persons who have the necessary knowledge, skills and
experience. Any work not described here may only be performed by the manufacturer's customer
service team or by the manufacturer.
During all servicing work, the compressed air connection and the control line between
the stapler and the production system must be disconnected.
WARNING
Unintentionally activating the stapler when emptying the magazine can
result in serious or fatal injury.
➢Disconnect the stapler from the compressed air supply before
cleaning it.
➢Remove the magazine and all staples from the feed channel and
on feed bridge.
Cleaning the housing and outer surface
Important
The stapler or accessories can be damaged by using unsuitable cleaning agents.
➢Only use a dry, slightly moistened cloth or a cloth moistened with mild soapy water for
cleaning the stapler.
