Position the battery pack to the charger, aligning the tongue on the battery pack with the slot in the
charger. Insert battery pack into charger (see Fig. 5). DO NOT FORCE. If battery pack does not slide
in easily, it is being inserted incorrectly: Realign battery pack tongue with charger slot and try again.
The green light (A) Fig. 5, should begin to glow continuously, indicating that the battery pack is
receiving a “Fast Charge” (if the green light does not glow continuously, or if the red light (B)
Fig. 5, also begins to flash: see DIAGNOSTICS). After approximately one hour, the “Fast Charge”
indicator light should go out indicating that the battery pack is fully charged and that the charger is
now in a “Trickle Charge” mode. The battery pack can be left on “Trickle Charge” until you are ready
to use it.
Depending on room temperature, line voltage, and existing charge level, initial battery charging may
take longer than one hour.
Disconnect charger from power source when not in use.
DIAGNOSTICS
The FLEX Charger is equipped with a diagnostic system that automatically checks the battery pack
each time a pack is inserted into the charger. If no problems are found, the charger will auto-
matically switch to “Fast Charge” mode as described in NORMAL CHARGING. If a problem is found,
it will be indicated by the charger indicator lights (see Fig. as follows:
l
Green light (A) continues to flash after battery pack is inserted in charger: indicates that the
battery pack temperature is either too high or too low for charging. If left alone, the charger will
continue to monitor the battery pack temperature and will begin charging when the temperature
reaches an acceptable level.
l
Green light (A) glows continuously and red light (B) flashes: indicates that the battery pack is
receiving a “Fast Charge”, but the pack is weak and will provide reduced performance (the pack
is still
but will not provide maximum power or work per charge). This battery pack will
probably require replacement in the near future.
l
Green light (A) continues to flash and red light (B) flashes: indicates that the battery pack has
failed (pack is not chargeable and requires replacement).
INSTALLING OR REMOVING BATTERY PACK
TO REMOVE BATTERY PACK: Depress the two battery release buttons (A) Fig. 6, (one button on
each side of battery pack) and pull battery pack out of tool.
TO INSTALL BATTERY PACK: Align battery pack with opening in tool handle and push battery pack
into handle until it locks in place.
MAINTENANCE
KEEP TOOL CLEAN
All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic
parts. They could very possibly dissolve or otherwise damage the material.
FAILURE TO START
Should your tool fail to start, make sure battery pack is charged and properly installed in drill.
