caustic. The battery charger therefore
needs to be switched off in order to prevent
accidents and to allow the battery to cool
down.
• Duringchargingso-calleddetonatinggas
can be liberated. That is why the filler caps
areunscrewedbeforecharging(doesnot
apply to closed batterys, this means Battery
chargerswithoutfillercaps).Charginghas
to take place in a thoroughly ventilated
space.
• Thebatterychargerdoesnotstop
automatically after charging. For this
reason it needs to be switched off and
disconnected from the battery. Do not leave
the battery charger connected to the mains
voltage after the battery has been charged
completely.
• Thisrangeofdevicesisonlysuitablefor
accumulators containing lead and acid,
as specified in table 1, and are capable
of charging accumulators and starting
vehicles. These devices may not be used
for non-standard batteries and accessories.
To avoid the danger of fire and electric
shock,theymayalsonotbeusedasDC
power supplies.
• Thechargermustonlybeconnectedto
an appropriate power socket with an earth
connection.
• Youshouldhavewaterandsoapywater
available when using the accumulator.
The accumulator contains corrosive
substances that are dangerous to the skin
and especially the eyes. If you should
accidentally come into contact with these
substances, immediately rinse the affected
region with water and seek medical help.
• Theaccumulatorstoresagreatdealof
energy. The plus and minus terminals
should not be shorted with metal objects or
this may cause a short circuit resulting in
personal injury or fire.
• Non-rechargeablebatteriesmaynotbe
charged.
• Firstconnectthebatteryterminalthatisnot
connected to the vehicle chassis. The other
connection is then made to the vehicle
chassis, away from the battery and fuel
lines. Only then should the battery charger
be connected to the mains power supply.

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.
• Thechargermustnotbeplacedontopof
the accumulator or vice-versa. This is both
illegal and unsafe
• Iftheaccumulatortemperaturerisesabove
40ºCthenthechargingcurrentshould
be reduced, and if the temperature rises
above45ºCthenyoushouldstopcharging
and only resume charging when the
temperature has dropped.
• Nowplugthepowerplugintothemains
socket and set the switch to “6V/12V”.
When charging, you should keep an eye on
the current meter to check that the indicator
