▶ Battery Charge Indicator

This tool is equipped with a charge
indicator 9 that tells you how much
charge your battery has. When the light
is red, the battery is almost empty.
Note: Red light may also indicate that
the tool is stalling. Refer to "Electronic
Monitoring" on page 16.
When the battery is depleted, the tool
will turn off automatically. This will be a
sudden stop as opposed to a gradual
slow down of the tool. Simply recharge
the tool.

Lithium-ion battery will hold its
charge while in storage for up to 2
years so it's always ready when you
need it.
The power adapter was designed to
fast charge the battery only when the
battery temperature is between 32˚F
(0˚C) and 122˚F (50˚C).
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. For service of
your tool, please contact Dremel at
1-800-437-3635.
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 USB terminals for dirt.
Clean with cotton swab and alcohol if
necessary.
d. Check to see if USB cable is
properly connected to the tool and
the power adapter.
e. If you still do not get proper
charging, send tool and power
adapter to your Dremel Service
Center.
