Generally, no other maintenance work is necessary. Heavy contamination can cause malfunctions. We
recommend overhaul by J. Schmalz GmbH in this case.
The replaceable sealing plates are described in the “Spare Parts and Wearing Parts” section.
If the sealing plate shows mechanical damage, it can be repaired up to a certain point using standard
vulcanizing adhesive (e.g. adhesive for repairing the inner tubes of bicycles).

Functional Check of the Vacuum Valve (Gripper FMP-i)
On area grippers FMP-i, dirt may accumulate in the bore hole in the hose connector (on the
filter) shown in the diagram. The filter must be cleaned regularly based on the amount of dirt.
Dismantle and clean separately as described in the section entitled “Mounting the Valve
Assembly”.
Note: Do not blow in with compressed air when assembled.
Functional test
To test the functions of the integrated vacuum valve, you must operate the vacuum valve while the suction points are
free (without a workpiece).
If the vacuum valve is closed (suction off) during operation (while the vacuum generator is running), then the applied
vacuum level in the gripper should drop to the ambient pressure after a short time. The blow-off function can also be
tested. Here, an audible noise can be heard from the compressed air that flows out when “Suction” is ON.
If the vacuum valve is opened during operation (“Suction” ON and “Blow off” OFF), then an appropriate vacuum
should build up in the area gripper FMP-S. If the vacuum level does not build up or drop correctly, replace the vacuum
valve completely or send it to Schmalz for maintenance.

Maintenance Schedule
Schmalz stipulates the following checks and inspection intervals. The operator must comply with the legal
regulations and safety regulations applicable at the location of use. These intervals apply to single-shift
operation. For heavier use, such as multi-shift operation, the intervals must be shortened accordingly.
