SAFETY INSTRUCTIONS
ź
Before using the charger please read the operating instructions that contain important information for
working with the charger safely.
ź
The warranty cannot be applied if the charger gets damaged due to non-compliance with these
instructions.
ź
The manufacturer is not liable for any consequential damages to property or personal injury caused by
improper use or non-compliance with the safety instructions.
ź
For safety reasons the charger cannot be modified nor its technical specification changed in any way.
ź
The battery charger can only be used with the supply voltage of 220V - 240V ~50Hz/60Hz.
ź
Never use the device to charge other types of batteries (NiCd, NiMH, Li-Pol etc.). There is the serious
risk of fire or an explosion if you do so.
ź
If you notice any damage on the product, stop immediately using the charger.
ź
Maintenance, installation or repair works may only be performed by an expert or a qualified workshop.
ź
Use only the original spare parts for repair work. The use of any other spare parts may lead to serious
damage of charger and personal injury.
ź
When using the charger pay special attention if children are present. Do not allow children to play with
the charger. Store always the charger out of their reach.
ź
Do not use the charger at an ambient temperature higher than 40°C and relative humidity above 80%.
ź
Charging lead-acid batteries may lead to the production of explosive gases. Do not try to charge non-
rechargeable batteries.
ź
Do not use the charger in rooms where is the risk of presence of combustible gases, solvents, higher
amounts of coal dust and other combustible materials. Make sure the room is properly ventilated
during the charging process. Never use the charger in poorly ventilated rooms.
ź
Keep the charger as well as batteries away from any sources of ignition. Sparking may occur when the
rechargeable battery is connected or disconnected. Do not smoke when using the charger.
ź
Never use the charger immediately after having taken it from cold into the warm room. Condensing
moisture can cause damage and there is also the risk of electric shock.
ź
The charger can be only used by persons who have sufficient knowledge and experience with using
similar devices.
ź
Before charging make sure the voltage of battery you want to charge is really 12V.
ź
Before connecting the charger to the battery make sure the battery has been disconnected from all
devices the battery is powering.
ź
Always disconnect the ground connection from the rechargeable battery first and only then the positive
terminal. Ensure the correct polarity when connecting batteries to the charger (red terminal of the
charger = plus/+ black terminal of the charger = minus/-).
ź
Follow strictly all safety instructions given by battery manufacturer. Never disassemble the battery.
ź
Lead-acid batteries contain corrosive acids. Avoid contact with eyes or skin. After contact with the skin,
thoroughly clean the affected area with soap and water. If acid gets into eyes immediately rinse eyes
with cold running water and immediately seek for medical help.
RECYCLING
ź
After the end of charger service life, the charger must be handed over to a collection point for recycling
of electrical and electronic parts. Recycling symbols are written on the product and its packaging.
Materials the charger is made of are recyclable according their specifications.

When the battery is fully charged, the LED indicator
will light up and the charger will
automatically switch to the maintenance charge mode.
BOOST MODE (MAXIMUM CHARGING VOLTAGE 0.25V ± 16V, 7A).
ź
This mode is suitable for charging lead-acid batteries containing calcium with capacity over of 14Ah
and regeneration of deeply discharged standard lead-acid batteries which have been discharged due
to acid stratification.
ź
Be careful! The high voltage in this mode may result in the loss of battery fluid.
ź
To select this mode, press down the button
until the LED indicator
lights up.
ź
When the battery is fully charged, the LED indicator
will light up and the charger will
automatically switch to the maintenance charge mode.
ź
This mode can also be used for batteries, for which the manufacturer recommends higher charging
voltages. Always follow the manufacturer's instructions.
AUTOMATIC REGENERATION
ź
This mode is designed to regenerate deeply discharged batteries and cannot be separately set up.
The charger after connecting to the battery, automatically recognizes the battery is deeply discharged
and begin to charge the battery by using lower current. When the battery reaches normal voltage
the charger start charging the battery normally. The maximum time of the regeneration mode
is 20 minutes. If no adequate battery voltage can be achieved during this time, the charger will stop
charging, the battery will be detected as defective and the indicator of damaged battery
will light
up.
DETECTION OF DAMAGED BATTERY
ź
The charger is able to recognize if the battery is damaged, a short circuit occurs, positive and negative
terminals are reversed. In this case the charger will not begin charging but the LED indicator
will
light up.
CLEANING CHARGER
ź
Disconnect the charger from the battery and from the electrical outlet before cleaning. Use a dry and
soft cloth to clean the outer surface of charger. Do not use any aggressive chemical cleaners.
