CHARGING INSTRUCTIONS

1. CHARGING YOUR BATTERY PACK

WARNING: The charger and battery pack are specifically designed to work together so do not attempt to use any other devices. Never or allow metallic objects into your charger or v pack connections because an electrical and hazard will occur.

Your battery pack is partly charged and needs to be fully charged before first use.

3. HOW TO CHARGE YOUR BATTERY CHARGING PROCEDURE

1) Plug the charger into an appropriate outlet (220-240 V).
2) Slide the battery pack into the charger as shown in illustration A., the LIGHT will become green and flash to show charging has started.
3) After charging approx. 25 mins (2.0 Ah) / 30 mins (2.5 Ah) / 50 mins (4.0 Ah) / 60 mins (5.0 Ah) / 77 mins (8.0 Ah), the light will stay green without flashing, which means the battery is fully charged.

WARNING: 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 a "smart charger" that is designed to provide you information on the status of your battery charge. Indicator lights n the table below will show the charging status.

If you receive a defective battery indication light (red on), insert a new battery 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 0°C or more than 60°C.
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 (the light will be red and flash), its internal fan will rapidly cool the battery to the correct temperature. When the charger detects a battery pack that is too 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.

MOUNTING CHARGER ONTO THE WALL

Install screws (not provided) in the wall. Use screws sufficiently strong to hold the combined weight of the charger and battery pack. (See Fig. B)

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°C-24°C). Do not charge the battery pack in air temperatures

below 0^irc C, or above 40^irc C. This is important as it can prevent serious damage to the battery pack.

1. Never freeze your charger or immerse charger in water or any other liquid.
2. 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.
3. When charging it is normal that the charger and battery pack may become warm to touch.
4. If the battery pack does not charge properly:
   a. Check current at power outlet by plugging in another appliance.
   b. Plug and unplug to check whether the charger is ok.
   c. Check whether the battery has been damaged
   d. Move the charger and battery pack to a location where the surrounding air temperature is approximately 18^irc C- 24^irc C.
   e. If the charging problem persists, take the tool, battery pack and charger to an authorized service center.
   f. 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

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

a) Check if the charger and the battery pack are specifically designed for working together.
b) 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.

2. REASONS FOR DIFFERENT CHARGING TIMES

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

a) If the battery pack is only partly discharged it may be re-charged in less than rated charging time.
b) 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.

MAINTAIN TOOLS WITH CARE

Remove the plug from the socket before carrying out any adjustment, servicing or maintenance. Your tool requires no additional lubrication or maintenance. Never use water or chemical cleaners to clean your power tool. Wipe clean with a dry cloth. Always store your power tool in a dry place. If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or similarly qualified persons in order to avoid a hazard.

ENVIRONMENTAL PROTECTION

Waste electrical products must not be disposed of with household waste. Please recycle where facilities exist. Check with your authorities or retailer for recycling advice.

PLUG REPLACEMENT(ONLY FOR REWIRABLE PLUG OF UK & IRELAND)

If you need to replace the fitted plug then follow the instructions below.

IMPORTANT

The wires in the mains lead are colored in accordance with the following code:

BLUE = NEUTRAL

BROWN = LIVE

As the colors of the wires in the mains lead of this appliance may not correspond with the colored markings identifying the terminals in your plug, proceed as follows. The wire which is colored blue must be connected to the terminal which is marked with N. The wire which is colored brown must be connected to the terminal which is marked with L.

WARNING! Never connect live or neutral wires to the earth terminal of the plug. Only fit an approved BS1363/A plug and the correct rated current fuse which is used in the plug.

NOTE: If a moulded plug is fitted and has to be removed take great care in disposing of the plug and severed cable, it must be destroyed to prevent engaging into a socket.
