8 Maintenance, servicing
WARNING
IMPORTANT
The drive medium must be clean (filter
≤ 5 µm, class 3).
Unfiltered compressed air causes
higher wear and tear, congestion of
the silencer and the complete failure
of the impactor. The servicing intervals
become shorter.
Maintenance schedule
The maintenance must be carried out monthly.
DANGER
IMPORTANT
Shut off the compressed air before any
inspection or maintenance work and
secure the machine to prevent it being
turned on accidentally!
The maintenance intervals essentially depend on the operating time and the
purity of the drive medium.
In particular in the devices operated with oil-free and/or dried compressed air a
film can build up from increased wear that can slow down the function.
If this is identified (loss of performance, possibly even stopping) the vibrators are
to be cleaned and if necessary the sealing rings replaced.
The servicing intervals become shorter with the life of the vibrator.
Cleaning the vibrators:
During cleaning of the vibrators the piston must be dismantled. The film must be
removed with an oiled rag from inside the housing as well as from the piston.
Alternatively, maintenance, repair and major overhaul can be carried out by Netter
Vibration.
Screw connections
After one hour of operation (after the initial start-up)
and thereafter on a regular basis, screw connections
must be checked tightened and secured with Loctite
where necessary.
Air supply hoses
Check for permeability and kinks. If necessary, clean
and remove kinks.
Silencer Clean and check it is working.
Mist lubricator
Ensure that mist lubricator is working correctly (contents
going down? Drop count/hr?). Top up the oil.
Maintenance unit
filter
If necessary, replace filter element, empty filter and
clean filter insert (wash it out).
Check for not visible
wear:
Because of the tight fit a small degree of wear can already
lead to a reduction in performance. Pull the piston with a
jerky movement out of the device (possibly remove the O-
ring on the piston beforehand). Nevertheless no metallic
stop must take place otherwise the air cushion is no
longer effective (reduction of performance, incipient
wear).
