8.4 Cleaning the twist ring
A non-contacting twist ring is used to switch on the Lite-Ex PL 30 (see description
above). Dirt or moisture does not effect the function. The twist ring is easy to clean
if excessive amounts of dirt and grime have made it difficult to turn. First take off the
torch body and remove the batteries (see section 8.3 Battery replacement). Remove
the twist ring by sliding it off the back of the torch, and then clean the ring. When
putting the twist ring back on, make sure that the arrow marks on the ring line up
with the alignment screw on the bottom part of the torch head (see illustration 1).
Then re-insert the batteries, and screw the body of the torch back on.

8.5 Lamp replacement

The Lite-Ex PL 30 is equipped with an extremely long-lasting LED lamp. Replacing
the LED is normally not required. If, however, the torch is defective or the brightness
of the torch has diminished, it should be sent to ecom instruments for inspection or
repair. Under no circumstances should you attempt to open the torch head. Manipu-
lating the torch head or LED on your own poses a risk to the safety of the torch and
is not permitted.
8.6 Replacing the spare disc
The torch head is protected by the housing head that surrounds it as well as an
additional disc, which is positioned over the opening where the beam is emitted. The
disc is made of high-quality material. Should, however, the disc break, it is possible
to replace it. To replace the disc, hold on to the body of the Lite-Ex PL 30 and
the twist ring, and carefully unscrew the housing head by turning it anticlockwise.
Clean the housing head thoroughly to remove any remaining pieces, and check the
sealing ring for damage. After this has been done, you can install a new glass disc
and, if necessary, new sealing rings. Only spare sealing rings of ecom instruments
are allowed. The sealing ring is positioned between the housing head and the disc
(see illustration 1). When putting the housing head back on, ensure that the seal is
positioned properly on the disc. After installation, you should not be able to see any
part of the sealing ring through the opening where the beam is emitted. If the inside
of the torch head or lens is also damaged, the torch should be sent to the manufac-
turer for repair.

9. Repairs

Repair work is subject to the nationally valid regulations and directives. We therefore
recommend that such work be performed by ecom instruments GmbH, Germany, as
all repairs must be examined to ensure functional safety.
