Always wear safety glasses and old
clothes during working with the battery ,
because battery acid is a biting product!
3. INSTALLATION
Before putting the battery charger into operation
the following steps need to be taken (Fig. 1):
If the battery is still connected, it needs to be
•
disconnected,
first the negative terminal (A);
•
then the positive terminal (B)!
•
It is advisable to remove the battery from the
vehicle before charging it.
Check the level of the battery acid. For this
•
purpose remove the battery stoppers first,
then check the acid level and, if necessary, fill
up with distilled water (available from the
chemists’). The level of the electric charge can
be checked with a hydrometer.
Clean the connections and the terminals. This
•
can be done with a steel wire brush or with
sandpaper.
Connect the positive clamp of the charger
•
(red) to the positive terminal (+) of the battery.
Then connect the negative clamp of the
charger (black) to the negative terminal (-) of
the battery.
Check if the clamps of the charger are firmly
•
connected to the battery.
The following steps need to be taken with the
•
help of the information of the charge control
display.
(Caution! (1) Our chargers are only suitable for
•
those accumulators having a residual voltage
above 2 V - 4 V. No current flows into batteries
having a residual voltage below 2 V - 4 V (2).
The current meter only provides a general
indication and not an exact measurement).
4. OPERATING THE BATTERY
CHARGER
The charging process starts after connecting the
clamps correctly to the battery and connecting the
plug to the mains. The charging current is visible
on the display on the front Fig. 2).
The charging process starts when the red light
•
comes on.
The battery is fully charged when the green
•
light comes on.
Overload
When the charging current becomes too high the
red light will indicate that there is an overload and
the charging process will stop.
After cooling down, the charger will start
automatically again (red light goes out again).
Reverse
The red light indicates that the battery charger is
not connected correctly to the battery: the clamps
have to be exchanged (red clamp on + and black
clamp on -).
6V / 12V
The battery charger can charge batteries of 6V
and 12V. For this purpose push the switch at the
right side of the front panel in chosen position.
Check charged battery
On the basis of the specific gravity of the battery
acid can be gathered if an battery is fully loaded
or not. With the help of a specific gravitymeter the
specific gravity can be appointed.
Empty battery: s.g. = 1.13 kg/dm

Full battery: s.g. = 1.28 kg/dm

5. MAINTENANCE
Always remove the plug from the mains socket
when the battery charger is being serviced or
cleaned. Never use any water or other liquids
when cleaning the charger. Keep the cable
and your battery charger clean. Some cleaners
and solvents (petrol, thinner) can affect or dis-
solve plastic parts. These products contain
a.o. benzene, trichloroethylene, chloride and
ammonia.
Defective batteries
Damaged batteries which do not retain their
•
charge. It is often the case that batteries which
are in very bad condition can no longer be
charged; they need to be replaced because
they do not retain their charge.
Short circuited batteries.
•
If, after several hours the battery charger still
does not indicate that the battery is being
charged, this usually means that one of the
elements is short circuited. The battery needs
to be replaced.
