may increase the risk of electric shock or fire. If your charger becomes damaged or malfunctions,
immediately cease use and contact Hardkorr.
• To reduce risk of damage to the electric plug and cord, pull by plug rather than cord when
disconnecting the charger. Make sure the cord is located so that it will not be stepped on, tripped

disconnected from 240V power.
• Some batteries contain explosive gases. Before charging or using your battery, it is important you
read your battery’s user manual.

CHARGE ALGORITHM

7OPERATION
CONNECTING THE CHARGER
CHARGING THE BATTERY
IF YOUR BATTERY IS INSIDE A VEHICLE:
IF YOUR BATTERY IS NOT INSIDE A VEHICLE:
1. Position cables to ensure they are clear of doors, hood and engine components which could cause
damage to the cables.
2. Ensure you know which is the positive and which is the negative battery terminal.
3. Determine which battery terminal is grounded to the chassis. Generally (but not always) the
negative terminal is grounded.
4. For negative-grounded vehicles, connect the positive (red) battery clamp or ring terminal to the
positive terminal of the battery. Connect the negative (black) battery clamp or ring terminal to the
vehicle’s chassis, away from the battery, fuel lines or moving parts.
5. For positive-grounded vehicles, connect the negative (black) battery clamp or ring terminal to the
negative terminal of the battery. Connect the positive (red) battery clamp or ring terminal to the
vehicle’s chassis, away from the battery, fuel lines or moving parts.
6. Connect the battery to a suitable AC power socket, and check that the POWER LED light
illuminates.
1. Ensure you know which is the positive and which is the negative battery terminal.
2. Connect the positive (red) battery clamp or ring terminal to the positive terminal of the battery.
3. Connect the negative (black) battery clamp or ring terminal to the negative terminal of the battery.
4. Connect the charger to a suitable AC power socket, and check the POWER LED light illuminates.
1. Select the appropriate charge program by pressing the MODE button repeatedly until the LED light
next to your suited battery program is illuminated. Note: If only the POWER LED light is lit, it means
the charger is in standby mode.
2. Once a charge mode is selected, after a couple of seconds the charger will commence operation
and the CHARGE LED light will illuminate.
3. You can stop charging at any time by pressing the MODE button until the charger returns to
standby mode.
4. The charger has a memory function and will remember your program setting even if disconnected.

mode. Simply connect the charger to the sleeping battery and it will automatically deliver special
small-current pulses until the battery has recovered enough to be charged normally.

TROUBLESHOOTING &
MAINTENANCE
TROUBLESHOOTING
MAINTENANCE
If the fault light is illuminated, it will be due to one of three potential faults: reverse polarity, short circuit,
or over temperature. Faults can be identified and resolved using the following procedure:
1. Immediately disconnect the AC plug and clamps/ring terminals, taking care to follow correct
procedure (see page 8).
2. Feel the body of the charger to see if it has become excessively warm. If so, it is likely that the
over-temperature protection was activated. Allow the charger to cool before reconnecting.
Consider whether it is necessary to move the charger to a different location to prevent it
overheating again.
3. If it does not appear to be a temperature issue, try to reconnect the charger, taking care to
observe correct polarity. If the fault then appears to be resolved, it is likely that the reverse
polarity protection circuit was activated.
4. If the charger again displays the fault light after reconnection, and you are certain that the
clamps/eyelets are connected correctly, there may be a short circuit. Immediately discontinue use
of the battery charger and contact Hardkorr for further advice.
Follow these basic maintenance procedures to ensure your charger remains in optimum condition and
delivers years of dependable service.
1. After each use, wipe off the battery charger clamps or ring terminals and charger body with a
clean, damp cloth. A mild soap solution may be used if required.
2. Keep the charger cables loosely coiled during storage to prevent damage. We do not
recommend winding them around the charger body.
3. Store the charger in a cool, dry place.
4. Prior to next use, examine the charger cables, clamps and ring terminals to ensure they are free
of obvious damage. If any damage is apparent, do not use the charger. Contact Hardkorr for
further advice.
