1.2. GENERAL SAFETY
▲DANGER! BE AWARE, LEAD-ACID BATTERIES GENERATE EXPLOSIVE GASES DURING NORMAL BATTERY OPERATION.
FOR THIS REASON, IT VERY IMPORTANT TO READ AND FOLLOW THESE INSTRUCTIONS CAREFULLY, EACH TIME YOU USE
THE CHARGING EQUIPMENT.
9Follow these instructions and those published by the battery and vehicle manufacturers, and the maker of any equipment you intend to
use in the vicinity of the battery. Remember to review warning marks on all products and on engines.
WARNING! Modern vehicles contain extensive electronic systems.
You are required to check with the vehicle manufacturer, for any specic instructions regarding the use of this type of equipment on
each vehicle.
9 No liability will be accepted for damage / injury, where this product is not used in accordance with all instructions.
1.3. PERSONAL PRECAUTIONS
9Ensure there is another person within hearing range of your voice and close enough to come to your aid, should a problem arise when
working near a lead-acid battery.
9Wear safety eye protection and protective clothing. Avoid touching eyes while working near battery.
9Have fresh water and soap nearby in case battery acid contacts skin, clothing or eyes.
9 Wash immediately with soap and water if battery acid contacts skin or clothing. If acid enters eye, flush eye immediately with cool, clean
running water for at least 15 minutes and seek immediate medical attention.
9Remove personal metallic items such as rings, bracelets, necklaces and watches. A lead-acid battery can produce a short-circuit current
which is high enough to weld a ring or the like to metal, which would cause severe burns.
9Ensure hands, clothing (especially belts) are clear of fan blades and other moving or hot parts of engine, remove ties and contain long hair.
8DO NOT smoke or allow a spark or flame in the vicinity of battery or engine.
1.4. CHARGING SAFETY INSTRUCTIONS
9Familiarise yourself with the application and limitations of the charger as well as the potential hazards.

4. i OPERATION
4.1. PREPARATION
It is important to correctly prepare for charging, ensuring that you follow Section 1 safety regulations carefully. Check that the capacity
of the battery is compatible with the charger output.
4.1.1. Follow any vehicle manufacturer’s instructions regarding battery charging. Note special instructions for in-vehicle charging.
4.1.2. Check polarity of battery posts. A positive (pos, p, +) battery post may have a larger diameter than a negative (neg, n, -) post;
4.1.3. Connect the battery lead plastic plug to the charger / maintainer plastic plug, see g.1.
4.2. BATTERY CHARGING
4.2.1. Follow the battery manufacturer’s recommendations for battery cell caps
during charging. Loosen cell caps if applicable.
4.2.2. Open all battery compartments and ventilate for at least 15 minutes before
plugging into the mains supply.
4.2.3. Connect the battery lead terminal rings or alligator clips directly to the
corresponding battery posts.
4.2.4. Position the RED terminal ring or alligator clip on the POSITIVE post
connector.
4.2.5. Position the BLACK terminal ring or alligator clip on the NEGATIVE post
connector. Make sure all battery connections are tight and clean.
4.2.6. Plug into the mains supply, using a suitably rated heavy duty extension cord.

4.2.9. If the battery voltage is more than 7.5V, the charger will charge the batteries according to 12V mode, the 12V LED LIGHT will turn
RED. If the battery voltage is less than 7.5V, the charger will charge the batteries according to 6V mode, the 6V LED LIGHT will turn
RED, see g.2.
4.2.10. The charger begins charging with 0.8A low current to recover the batteries automatically if the batteries are not full.
4.2.11. LED LIGHTS:
When the red light is on it indicates that the battery is correctly connected and the charger is charging it. The charger will deliver its full
rated current until this light turns from red to green (charged).
When the battery is fully charged, the LED will turn to green and the
charger will switch to a storage/maintenance charge mode, see g.2.
The charger will automatically monitor and maintain the battery with 0.8A
charging current.
4.2.12. When you are ready to use your vehicle, unplug from the mains supply,
followed by unplugging your battery terminal lead from the charger.
4.2.13. The battery lead with terminals may be left attached to the battery.
Use care to safely stow the battery lead away from heat sources, sharp
edges and avoid pinching or crushing. The battery lead with alligator clips
should be removed before installing or using the battery.
IMPORTANT -- If the battery is totally dead (below 4 volts) the Bank
charger will not start. This is due to its internal safety circuit. The
charger safety circuit must sense more than 4 volts before it will allow
the charger to turn on. If the battery voltage is below 4 volts, the
charger will not operate and the lights will not turn on. Have the
battery checked by a dealer if the battery voltage is very low.
Most 12 volt lead acid batteries are likely to be defective if their voltage
is below 9 volts
5. MAINTENANCE
5.1. Cleaning and user maintenance should be carried out by competent persons.
5.2. After use and before performing maintenance, unplug and disconnect the battery charger.
5.3. Use a dry cloth to wipe all battery corrosion and other dirt or oil from the battery connectors, cords, and the charger case.
5.4. Ensure that all of the charger components are in place and in good working condition, for example, the plastic boots on the battery
clips.
5.5. Servicing does not require opening the unit, as there are no serviceable parts.
5.6. All other servicing should be performed by qualied service personnel.
5.7. If the mains cable is damaged, do not use until repaired.
5.8. Store the charger unplugged, in an upright position. The cord will still conduct electricity until it is unplugged from the mains.
5.9. Store inside, in a cool, dry place.
8DO NOT store the connectors clipped together, on or around metal, or clipped to cables. If the charger is moved around the shop or
transported to another location, take care to avoid/prevent damage to the cables, connectors and charger. Failure to do so could result
in personal injury or property damage.
