Electrical Safety

The electric motor has been designed for one
voltage only. Always check that the battery pack
voltage corresponds to the voltage on the rating
plate. Also make sure that the voltage of your
charger corresponds to that of your mains.
Your D WALT charger is double insulated
E
in accordance with EN 60335; therefore
no earth wire is required.
If the supply cord is damaged, it must be replaced
by a specially prepared cord available through the
D WALT service organization.

WARNING: No connection is to be
made to the earth terminal.
Follow the fitting instructions supplied with good
quality plugs. Recommended fuse: 3 A.

Inserting and Removing the
Battery Pack from the Tool (fi g. 3)
WARNING: To reduce the risk of injury,
never depress the battery release button
without removing the battery pack.
Depressing the battery release button
without removing the battery pack can
result in the battery pack falling out
unexpectedly.
NOTE: For best results, make sure your battery
pack is fully charged.
TO INSTALL THE BATTERY PACK INTO THE TOOL HANDLE
1. Align the battery pack (f) with the rails inside the
tool's handle (fig. 3).
2. Slide it into the handle until the battery pack is
firmly seated in the tool and ensure that it does
not disengage.

pull the battery pack out of the tool handle.
2. Insert battery pack into the charger as

FUEL GAUGE BATTERY PACKS (FIG. 3)
Some D WALT battery packs include a fuel gauge
E
which consists of three green LED lights that
indicate the level of charge remaining in the battery
pack.
To actuate the fuel gauge, press and hold the fuel
gauge button (n). A combination of the three green
LED lights will illuminate designating the level of
charge left. When the level of charge in the battery
is below the usable limit, the fuel gauge will not
illuminate and the battery will need to be recharged.
NOTE: The fuel gauge is only an indication of the
charge left on the battery pack. It does not indicate
tool functionality and is subject to variation based
on product components, temperature and end-user
application.
