instructions
Please read these operating instructions care-
fully so that you are familiar with, and are able to
use, all of the functions of your
Lite-Ex PL 10. For your own safety and informa-
tion please read the instructions on the following
pages carefully!
8.1 Assembly of the Lite-Ex PL 10
Fig. 1
8.2 Getting started
The supplied batteries must be inserted to begin
with (outside the Ex-area). In order to be able
to use the flashlight in the Ex-area it must be
ensured that the lamp head and the body of the
flashlight are screwed together tightly. The flash-
light can then be switched on by lightly rotating
the yellow ring switch clockwise.

8.3 Battery replacement
The batteries should be replaced if the level of
luminance is no longer deemed to be satisfac-
tory. It is advisable to change all 3 batteries at
the same time. Only the appropriate, approved
types of batteries may be used (refer to the table
with details of the type-tested batteries under
point 7: Technical specifications). To replace the
batteries grasp the lamp head firmly, twist the
body of the flashlight (incl. ring switch) anti-
clockwise and then remove it. The batteries can
then be removed from the battery compartment
and exchanged. After inserting the new batteries
(observe the correct polarity) the body of the
flashlight can be screwed back on. Please make
sure the flashlight has been screwed together
completely before switching it on again.
Battery replacement
- Only use type-tested batteries (see the table
under point 7: Technical specifications).
- Always replace all batteries simultaneously.
- Pay attention to the correct polarity.
- Dispose of depleted batteries in an appropriate
and environmentally friendly manner!
- When changing the batteries examine the
threads and seals for cleanliness and signs of
damage.
8.4 Cleaning the ring switch
A non-contacting ring switch is used to switch
on the Lite-Ex PL 10 (see description above). Dirt
and moisture do not impair the switching func-
tion. The ring switch is easy to clean if excessive
amounts of dirt and grime have made it difficult
to turn. Start by unscrewing the lamp head. (See
point 8.3 Battery replacement). The ring switch
24
can now be removed and cleaned. When it has
been cleaned replace the ring switch and rotate
it until it engages firmly in place (magnet must
be positioned on the shaft - ecom address side).
The lamp head can then be screwed back onto
the flashlight.
8.5 LED replacement
The Lite-Ex PL 10 is equipped with a long-life
LED bulb. Under normal conditions it is not
necessary to change the LED. If, however, the
torch is defective or the brightness of the torch
has diminished, it should be sent to ecom instru-
ments for inspection or repair. The LED housing
should not be opened!
Manipulating the torch head or LED on your own
poses a risk to the safety of the flashlight and is
not permitted.
8.6 Replacing the protective disc
The LED housing is protected by the surrounding
housing head and an additional protective disc,
which is located 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 do this grasp the body
of the Lite-Ex PL 10 and the ring switch and
then carefully unscrew the lamp head by turning
it anti-clockwise. To unscrew the lamp head
from the LED housing use an Allen key (AF4) to
secure the LED housing in place (see Fig. 2) and
unscrew the lamp head. The sealing ring can
now be replaced (only use original ecom sealing
rings). The LED housing should then be cleaned
thoroughly and the sealing ring checked for
signs of damage. If the sealing ring exhibits any
damage, it should also be replaced (the sealing
25
ring is set in a groove under the protective disc).
When replacing the lamp head on the LED
housing make sure the seal and disc are seated
properly. After assembly no part of the seal
should be visible through the opening where the
beam is emitted. If the LED housing or lens has
been damaged, the flashlight should be sent to
the manufacturer for repair.

8.7 Assembling the belt clip
Remove the belt clip from the plastic bag and
attach it to the side of the company logo using
the screw provided (see Fig. 3).
