Red Warning LED
The red warning LED 9 will illuminate
for one of the following reasons:
- Excessive tool temperature: turn the
tool off and remove the accessory
(Be careful – the accessory may be
hot). Then turn the tool on and
allow it to run without load so the
motor’s fan can help cool down the
tool.
- Excessive battery temperature: turn
the tool off, remove the battery
pack and allow the battery to return
to normal operating temperature
before resuming use.
- Tool stall / overload warning: too
much pressure is being applied to
the tool. Reduce pressure to hold
and guide the tool. Allow the speed
of the tool to do the work.
Fuel Gauge
This tool is equipped with a fuel gauge
11 that tells you how much charge your
battery has. A fully charged battery is
indicated when all three LED lights are
illuminated. As the battery discharges,
the lights will turn off one by one until
only one light is on. When the last light
starts "flashing", the battery is almost
empty. When the battery is dead, the
tool will automatically turn off. This will
be a sudden stop as opposed to a
gradual winding down of the tool.
Simply recharge the battery and reuse.
Charging Battery Pack
IMPORTANT CHARGING NOTES
1. The charger was designed to fast
charge the battery only when the
battery temperature is between 32˚F
(0˚C) and 113˚F (45˚C). If the
battery pack is too hot or too cold,
the charger will not fast charge the
battery. (This may happen if the
battery pack is hot from heavy use).
When the battery temperature
returns to between 32˚F (0˚C) and
113˚F (45˚C), the charger will
automatically begin charging.
2. A substantial drop in operating time
per charge may mean that the battery
pack is nearing the end of its life and
should be replaced.
3. Remember to unplug charger during
storage period.
4. If battery does not charge properly:
a. Check for voltage at outlet by
plugging in some other electrical
device.
b. Check to see if outlet is connected
to a light switch which turns power
“off” when lights are turned off.
c. Check battery pack terminals for
dirt. Clean with cotton swab and
alcohol if necessary.
d. If you still do not get proper
charging, take or send tool, battery
pack and charger to your local
Dremel Service Center.
Note: Use of chargers or battery packs
not recommended by Dremel in the
battery/charger list will void the
warranty.
DREMEL CHARGER GAL12V-20
Plug charger cord into your standard
power outlet, then insert battery pack
12 into charger (Fig. 8).
If the indicator lights are “OFF”, the
charger is not receiving power from
power supply outlet.
The charger’s green indicator light will
begin to “BLINK”. This indicates that the
battery is receiving a fast charge. Fast-
charging will automatically stop when
the battery pack is fully charged.
When the indicator light stops
“BLINKING” (and becomes a steady
green light) fast charging is complete.
The battery pack may be used even
though the light may still be blinking.
The light may require more time to stop
blinking depending on temperature.
The purpose of the blinking green light
is to indicate that the battery pack is
fast-charging. It does not indicate the
exact point of full charge. The light will
3 lights – 70–100% charge remaining
2 lights – 40–70% charge remaining
1 light – 20–40% charge remaining
1 "flashing" light – Below 20% charge
remaining. Be prepared for tool to
shut off.
