Servicing and Maintenance
5.1
Maintenance Information
The air drives of all air amplifiers are pre-treated with high-performance grease
during assembly and require no other type of lubrication.
During service and maintenance work on the air amplifiers, control slide valves and
air pistons must be treated with an acid- and silicone-free high-performance grease
provided by the manufacturer.
In the event of a stroke frequency of >= 150 strokes/min or an operating time of >
50%, a compressed air lubricator must be installed upstream of the air amplifier.

Maintenance
Possible fault
Cause of fault
Fault removal
Air amplifier fails to operate
at low air pressure.
Friction of o-rings
on control slide valve is too
high.
❑
Re-lubricate.
❑
Replace o-rings on
control slide valve.
Exhaust or control slide valve
covered with ice.
❑
Use water separator to
de-water compressed air.
Air amplifier does not operate
or operates only slowly.
Formation of residue in the
silencer.
❑
Clean the silencer.
❑
Replace, where
applicable.
O-rings on the control slide
valve are defective.
❑

rings.
Air amplifier fails to operate
or air escapes through the
exhaust.
O-rings on air pistons are
defective or worn out.
❑
Change and grease o-
rings.
NOTE
Use only original MAXIMATOR spare parts to maintain the air amplifiers.
NOTE
Exercise utmost cleanliness when repairing an air amplifier to ensure the proper
functioning and durability of the precision-machined parts.
