Start-up
When the worklight is switched on, the LED
flashes once (red light) and then the red light
stays on until the device is switched off.
4. Operation
Operation
If the battery of the worklight is flat (work-
light switches off automatically) and the
switch is in the “ON” position, the LED
flashes red. In this case, the battery must be
charged as follows.
Charging
The device must be switched off during
charging. Remove the rubber cover from the
charging socket (6). Plug the charger(s) pro-
vided in the scope of delivery into the charg-
ing socket and connect to a power source in-
tended for this purpose. In order to prevent
damage, do not use any chargers other than
those provided. When connected to the pow-
er source, the LED flashes once (red light)
and then the red light stays on throughout
the entire charging procedure. Once the
battery is fully charged, the LED flashes
green. Both the worklight and charger heat
up slightly during charging. After charging,
first disconnect the charger from the power
source and then remove the charging plug
from the charging socket (6). The worklight
is then on stand-by and can be switched on
using the switch (5).
Maintenance (care and cleaning)
The device can be cleaned using a slightly
damp cleaning cloth provided it is switched
off and disconnected from the power source.
The cleaned areas should be dried immedi-
ately using a dry cleaning cloth. The device
must not be switched on again until it is
fully dry. Only soapy water should be used
to dampen the cleaning cloth. No corrosive
or chemical cleaning agents should be used
for cleaning.
5. Maintenance
If the device is not used regularly, we rec-
ommend that the battery be charged and
discharged at least once a month in order to
preserve the battery function.
