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 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 

will become green and flash to show charging has 

started.

3)   After charging approx. 45 minutes, the light will 

stay green without flashing, which means the 

battery is full, and charging is completed.

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.

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, 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°Cand 24°C. Do not charge the battery
