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.
