Frequently Asked Questions - KAC15 KRESS

How to charge my battery with the KAC15 charger?

Plug the charger into a suitable mains socket (100-240 V). Insert the battery into the charger. The flashing green light indicates charging and becomes steady green when the battery is fully charged.

What does the red light on the charger mean?

A steady red light indicates a faulty battery. A flashing red light means thermal protection: the battery is too hot or too cold (temperature below 0°C or above 45°C). Let it cool down or warm up before recharging.

Can I charge batteries of other brands with this charger?

No, use only Kress batteries of the same model or recommended by Kress. Charging other batteries may damage the charger or battery and pose a safety risk.

How to know if the battery is fully charged?

The green light becomes steady when the battery is fully charged. Typically, charging time is about 20 minutes for a 2.0 Ah or 4.0 Ah battery (1 unit) and 35 minutes for an 8.0 Ah battery (1 unit).

What to do if my battery does not charge?

First check the socket voltage. Make sure the battery is compatible and inserted correctly. If the red light remains on, the battery is defective. Test with another battery. If the charger still does not work, contact customer service.

Can I use the charger outdoors?

No, the charger is designed for indoor use only. Protect it from rain, moisture and dust. Use it in a dry, well-ventilated place.

What is the ideal temperature for charging the battery?

For best performance and extended battery life, charge the battery at an ambient temperature between 18°C and 24°C. Avoid charging below 0°C or above 40°C.

How to maintain the KAC15 charger?

Always unplug the charger before cleaning. Clean it with a dry cloth. Never use water or chemicals. Store it in a dry, frost-free place. Ensure the ventilation slots are free of any objects.

What to do in case of a faulty battery detected by the charger?

The charger attempts to repair the battery for about 30 minutes (flashing green light). If the repair succeeds, charging resumes. If the light becomes steady red, the battery is irreparable and must be recycled at an approved center.

How to recycle the charger or batteries at end of life?

Do not dispose of electrical or electronic equipment with household waste. Drop them off at a local collection point or approved recycling center in accordance with the WEEE directive. Consult your retailer or local authorities for more information.

CHARGING PROCEDURE

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

CHARGING INSTRUCTIONS

1. CHARGING YOUR BATTERY PACK (NOT SUPPLIED)

WARNING: 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.

Your battery pack is UNCHARGED and you must charge once before use.

3. HOW TO CHARGE YOUR BATTERY (NOT SUPPLIED) (SEE FIG. A)

- CHARGING PROCEDURE

1) Plug the charger into an appropriate outlet.
2) Slide the battery pack into the charger. Normally, the relevant indication lights will flash in green color showing the battery is being 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 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 ProtectionThe temperature of battery pack is less than 0°C or more than 45°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 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.

- 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, then the battery pack is dead, and should be returned to a service center or recycling service center.

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 and 24°C. Do not charge the battery pack in air temperatures below 0°C, or above 40°C. 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 you battery, do not continue to use under this condition. You may charge a partially used pack whenever you desire with no adverse effect 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:

- Check current at power outlet by plugging in another appliance.

- Plug and unplug to check whether the charger is ok.

- Check whether the battery has been damaged

- Move the charger and battery pack to a location where the surrounding air temperature is approximately 18°C\~24°C.

- If the charging problem persists, take the tool, battery pack and charger to an authorized service center.

- 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.

MAINTENANCE

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 tool. Wipe clean with a dry cloth.

Always store your 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.

TROUBLESHOOTING

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 pack can be inserted into the charger only in one direction. Turn the battery pack around until it can be inserted into the slot, the indicator light should be green and flash when the battery pack 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.
