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.
