aid when you work near a battery.
Do NOT smoke, strike a match, or cause a spark in vicinity of battery or engine. Avoid
explosive gas, flames and sparks.
Remove all personal jewellery, such as rings, bracelets, necklaces, and watches while
working with a vehicle battery. These items may produce a short-circuit that may cause
severe burns.
Be extra cautious to reduce risk of dropping a metal product onto the battery. It might
spark or short-circuit a battery or other electrical hardware which may cause an explosion
or fire.
Wear complete eye protection, hand and clothing protection. Avoid touching eyes while
working near a battery.
Study all battery specific precautions such as removing or not removing cell caps while
charging and recommended rates of charge.
Clean battery terminals before connected with the charger. Be careful to keep corrosion
from coming in contact with eyes.
For a battery installed in a vehicle, first connect charger output lead to ungrounded
battery post - not connected to automobile chassis - in accordance with polarity
identification and then opposite polarity lead to chassis; do not connect to injector rails,
carburettors or fuel lines. Disconnect chassis lead first.
When it is necessary to remove a battery from vehicle to charge, always remove
grounded terminal from battery first. Make sure all accessories in the vehicle are off in
order to prevent an arc.
It is not intended to supply power to an extra-low-voltage electrical system or to charge
dry-cell batteries. Charging dry-cell batteries may burst and cause injury to persons and
property.
WARNING! NEVER charge a frozen, damaged, leaking or non-rechargeable battery.
If battery electrolyte contacts skin or clothing, wash immediately with soap and water. If
electrolyte enters eye, immediately flood eye with running clean cold water for at least
15 minutes and get medical attention immediately. If electrolyte is taken internally, drink
large quantities of water or milk; do NOT induce vomiting and get prompt medical
attention. Neutralize with baking soda any electrolyte that spills on a vehicle or in the
work area; after neutralizing, rinse contaminated area clean with water.
ELECTRICAL SAFETY.
Plugs must match the outlet. Never modify the plug in any way. Do not use any adaptor
plugs with earthed (grounded) products. Unmodified plugs and matching outlets will
reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body is earthed or
grounded.
Do not expose products to rain or wet conditions. Water entering the power tool will
increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power
tool.
Keep the cord away from heat, oil, sharp edvges and moving parts. Damaged or
entangled cords increase risk of electric shock.
When operating a power tool outdoors, use an extension cord suitable for outdoor use to
reduce the risk of electric shock.
SAFETY PRECAUTIONS FOR USING THE CHARGER

15A Battery Charger has ten modes: Standby, 6V STD, 12V STD, 24V STD, REPAIR(12V/24V) , 13.6V
SUPPLY and 12V JUMP CHARGE. Some charge modes must be held for three (3) seconds or / and
pressed to enter the mode. Do not operate the charger until you confirm the appropriate charge
mode for your battery.

USING REPAIR
This mode is for LEAD-ACID batteries only. It is an advanced battery recovery mode for
repairing old, idle, stratified or sulphated batteries.
NOT all batteries can be recovered. For optimal results, take the battery through a full
charge cycle, bringing the battery to full charge, before using this mode.
When this mode is chosen, ensure you press Mode button for choosing appropriate 12V
Mode(s) .
One REPAIR cycle can take up to eight hours to complete the recovery process and will
enter to charge (8 steps charging cycle) when completed. This mode uses a high charging
voltage and may cause some water loss in WET (flooded) cell batteries. Plus, some
batteries and electronics may be sensitive to high charging voltages. To minimize risks,
disconnect the battery from the vehicle before using this mode.
STEP 1: DIAGNOSIS (Check if battery has connected with the charger and also check
battery voltage)
STEP 2: DESULPHATION (If battery voltage is too low, programs automatically generate
pulsing current to remove sulphate, up to 5 hours)
STEP 3: ANALYSE (Check if the battery voltage reaches to the threshold after
desulphation, and charging begins if the battery voltage is OK)
STEP 4: SOFT START (Charge with echelon constant current)
STEP 5: BULK (Charge with constant maximum current until battery voltage is reached to
the threshold)
STEP 6: ABSORPTION (Provide gradually declining current charge for maximum battery
voltage)
STEP 7: ANALYSE (Test if the battery can hold charge)
STEP 8: MAINTENANCE (Continuously monitor the battery, and charging current will
intelligently adapt to the variable battery voltage).
