7. Cleaning and Maintenance
General
NOTE! Performing cleaning and maintenance regularly reduces the chances of equipment
failure.
CAUTION! Personnel performing any maintenance or cleaning must familiarize themselves
with the "Safety Instructions" on page 9 before attempting any of these procedures.
NOTE! For correct mounting/dismounting of fittings please see "Correct mounting/
dismounting of fittings" on page 51.
The Lippke 4000/4500 control units are maintenance-free. This particularly applies to the pneumatics
and electronic control systems.
Cleaning and maintenance of other items such as measurement accessories and needles etc. is
described in the following.
Parts
Parts required for maintenance purposes are listed in "Consumables and accessories" on page 75.
Cleaning
All control unit and measurement accessory surfaces should be cleaned using a mild soap solution and a
wrung cloth.
CAUTION! Never use hard tools or abrasive materials when cleaning any part of the device.
WARNING! Never use cleaning agents containing chlorinated solvents or acetic or
phosphoric acid. These constitute a health hazard and could damage the instrument.
Needles and test heads
Disassemble needles and test heads from time to time and check whether they are completely clean and
that all openings are free from dirt and residues. Any residues can be removed carefully by means of a
needle and liquids should be best blown out using compressed air.
Flushing with water and alcohol is also possible. After that, all parts should be blown out thoroughly with
compressed air to make sure that no liquids remain.
Hoses
All hoses should be disconnected regularly and blown through using compressed air.
