10. Faults:
The overload protection interrupts charging in the
event of overheating. Just let the charger cool
down, it turns itself on again automatically.
The flat fuse, accessible from the front, blows
in the event of a short circuit or polarity
reversal.
Only replace a blown flat fuse with the same
amperage, otherwise the safety of the battery
charger is no longer guaranteed. To do this...
• first pull the power plug out of the socket...
• and remove the charging clamps from the
battery.
• pull the defective fuse out with a crooked
crowbar.
• you can then push the new fuse into the
holder with your fingers – finished!
Should the new fuse burn through again
immediately or after a short time, then there is
a defect. On no account should you bridge
the fuse or replace it by a stronger one –
otherwise there is risk of fire!
Should the battery charger no longer function
or if damage is visible:
• Have a defective charger repaired first by
the service department, before using it
again! Otherwise the battery charger may no
longer be sufficiently safe!
• Do not try to repair a defective charger
yourself – if you are not an expert. There
could otherwise be risk of death through an
electric shock or risk of fire.

7. Care
Cleaning is not necessary, unless there is
visible dirt. If you want to clean the casing:
• Make sure before cleaning that the power
plug has been pulled out of the socket...
• and that the charging cables have been
taken off of the battery, to prevent a short
circuit.
• Clean the casing and the charging cables
with a damp cloth. Make sure that no
moisture gets into the charger
• Clean the charging clamps if there is rust or
any other dirt on them. This could otherwise
reduce the conductivity.
8. Storage
Store the battery charger in a dry room.
Protect the charging cable clamps from rust
and dirt by wrapping them thickly in plastic
foil! Rust and dirt reduce conductivity!
9. Disposal
There are no disposal regulations for the
materials used in this battery charger at the
time of writing these instructions. You can
dispose of it with your normal house rubbish.

Caution!
If the charging current does not decrease
significantly in the course of the total charging
time, this indicates a defective battery! This
may not be charged further under any
circumstances, to prevent overheating!
Caution!
If the charging current is higher than about
10% of the battery capacity, the in build gas
in the battery may be so much, that the
battery manufacturer provides an opening of
the battery closing-seal, to draw off possible
excess pressure.
Read the battery documents to inform your
self about opening the battery and the
dangers of with battery acid!
6.End of charging
When the charging is finished, e.g. according to
the calculated charging time or when the char-
ging current is low:
➌ First pull out the mains plug before taking
off the charging cables!
In this order you prevent the charging
cables, which have already been taken off,
from being live and causing a short circuit!
➋ Now first take the black charging cable off
the negative pole...
➊ and then the red charging cable off the
positive pole of the battery!
In this order you reduce the danger of a short
circuit, should the red charging cable
accidentally touch the metal chassis (earth).
Danger!
Never open the casing, there are no
operating controls inside it. There is risk of
death from an electric shock if you touch live
parts inside!
➊ First connect the red charging cable to the
positive pole of the battery,
➋ and then the black charging cable to the
negative pole of the battery.
In this order the danger of a short-circuit is
reduced, should the red charging cable
accidentally touch the metal chassis (earth)
on connecting!
➌ Now put the power plug into the socket –
the charging process will begin immediately.
5. Charging
This battery charger has no charging-time
control! Batteries which are charged for too
long can overload and thereby get damaged.
That is why the following points should be
observed to calculate the maximum charging
time:
The charging time depends on the battery’s
charged condition. If you do not know this
exactly, you can test it with a customary
acid-meter (as described in its instructions).
For information: Lead batteries are
considered...
- empty with an acid density of less
than 1.16g/cm 3
- half charged with an acid density
of 1.21 g/cm 3
- fully charged with an acid density of
more than 1.28g/cm 3
The charging time is calculated by the formula
“Battery capacity divided by the charging
current”. For example, for a battery capacity of
36 Ah and a charging current of 12 A, it would
theoretically be about 3 hours (3 h x 12 A = 36
Ah). “Theoretically”, because as the charging
time increases, the charging current sinks
and the fuller the battery becomes! Therefore:
➍ The measuring instrument on the charger
shows the charging current at the time of
reading. This is only close to the maximum
value at the beginning of charging. Observe
the decrease of the charging current to
calculate the actual charging time from the
middle value.
