CHARGING PROCEDURE

NOTE: Before using the tool, read the instruction book carefully.

CHARGING INSTRUCTIONS

1. CHARGING YOUR BATTERY PACK
   
   The charger and battery pack are specifically designed to work together so do not attempt to use any other devices. Never insert or allow metallic objects into your charger or battery pack connections because an electrical failure and hazard will occur.
2. BEFORE USING YOUR CORDLESS TOOL
   Your battery pack is UNCHARGED and you must charge once before use.
3. HOW TO CHARGE YOUR BATTERY
   CHARGING PROCEDURE
   1. Plug the charger into an appropriate outlet.
   2. Slide the battery pack into the charger. The LIGHT (3) will become green and flash to show charging has started.
   3. After charging 25mins (2.0Ah) / 30 mins (2.5Ah) / 45mins (4.0Ah) / 60mins (5.0Ah) / 100mins (8.0Ah), the light will stay green without flashing, which means the battery is full, and charging is completed.

When battery charge runs out after continuous use or exposure to direct sunlight or heat, allow time for the battery to cool down before re-charging to achieve the full charge.

CHARGING INDICATOR
This charger is designed to detect some problems that can arise with battery packs. Indicator lights indicate problems (see table below). If this occurs, insert a new battery pack to determine if the charger is OK. If the new battery charges correctly, then the original pack is defective and should be returned to a service center or recycling service center. If the new battery pack displays the same problem as the original Battery Pack, have the charger tested at an authorized service center.

Light	ON/ Flash	Status
Red on		Defective Battery
Red flash	- - - - -	Battery Temperature Protection The temperature of battery pack is less than 0oC or more than 45oC.
Green on		Fully Charged
Green flash	- - - - - -	Charging

BATTERY TEMPERATURE PROTECTION
This charger has a battery temperature protection feature. When the charger detects a battery pack that is too hot or cold (the light will be red and flash), it automatically activates the protection circuit, and suspends charging until the battery pack has reached the correct temperature. The charging process will then automatically begin (the light will be green and flash).
This feature ensures maximum battery life.

LEAVING THE BATTERY PACK IN THE CHARGER
If a fully charged battery pack is left in the charger, the Light will remain green. The battery pack will remain charging with a maintenance trickle current.

DEFECTIVE BATTERY PACKS
This charger will detect a defective battery pack. When a defective battery pack is inserted into the charger, the charger will try to repair it. This process will last about 30mins (the light will be green and flash). If the repair is successful, the charger will automatically begin to charge the battery pack to the highest capacity possible (the light will be green and flash). If the light becomes solid red, the battery pack is dead.
NOTE: Repaired battery packs are still usable but should not be expected to perform as much work as new battery packs.

IMPORTANT CHARGING NOTES:

1. For a new battery or a battery that has been in storage for sometime, please recharge the battery before use. If you want to store the battery for a long time, please fully charge the battery pack to ensure maximum battery life.
2. Longer life and better performance can be obtained if the battery pack is charged when the air temperature is between (18^oC-24^oC). Do not charge the battery pack in air temperatures below 4.5^oC, or above 40.5^oC. This is important as it can prevent serious damage to the battery pack.
3. Never freeze your charger or immerse charger in water or any other liquid.
4. When the battery pack fails to produce sufficient power on jobs that were previously done easily, please recharge your battery, do not continue to use under this condition. You may charge a partially used pack whenever you desire with no adverse affect on the battery pack.
5. When charging it is normal that the charger and battery pack may become warm to touch.
6. If the battery pack does not charge properly:
   1. Check current at power outlet by plugging in another appliance.
   2. Plug and unplug to check whether the charger is ok
   3. Check whether the battery has been damaged
   4. Move the charger and battery pack to a location where the surrounding air temperature is approximately 18^oC-24^oC.
   5. If the charging problem persists, take the tool, battery pack and charger to an authorized service center.
   6. Under certain conditions, when the charger is plugged into the power supply, the exposed charging contacts inside the charger can be shorted by foreign material. Foreign materials of a conductive nature such as metallic particles should be kept away from charger cavities. Always unplug the charger from the power supply when there is no battery pack in the charger or before attempting to clean.

PROBLEM SOLUTION

I CANNOT FIT THE BATTERY INTO THE BATTERY CHARGER. WHY?

1. Check if the charger and the battery pack are specifically designed for working together.
2. The battery can be inserted into the charger only in one direction. Turn the battery around until it can be inserted into the slot, the indicator light should be green and flash when the battery is charging.

REASONS FOR DIFFERENT CHARGING TIMES

The charging time can be affected by many reasons which are not defects in your product.

1. If the battery pack is only partly discharged it may be re-charged in less than rated charging time.
2. If the battery pack and ambient temperature are very cold/ hot, it may take longer to re-charge. Please find an appropriate environment with proper air temperature to start charging.
3. If the battery pack is very hot, remove battery pack from the charger and allow battery pack to cool first to ambient temperature and then recharging can be started.

MAINTENANCE

Remove the plug from the socket before carrying out any adjustment, servicing or maintenance.
Your battery charger requires no additional lubrication or maintenance. Never use water or chemical cleaners to clean your charger. Wipe clean with a dry cloth. Always store your charger in a dry place.
