performing an operation where the cutting tools
may contact hidden wiring or its own cord.

OPERATING INSTRUCTIONS
Installing or removing battery cartridge
For DA302D (Fig. 1)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, pull out the set plate
on the tool and grasp both sides of the cartridge while
withdrawing it from the tool.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Snap the set plate back into place. Be sure
to close the set plate fully before using the tool to pre-
vent the battery cartridge from accidentally falling out of
the tool.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
For DA392D & DA312D (Fig. 2)
• Always switch off the tool before insertion or removal of
the battery cartridge.
• To remove the battery cartridge, withdraw it from the
tool while pressing the push buttons on both sides of
the cartridge.
• To insert the battery cartridge, align the tongue on the
battery cartridge with the groove in the housing and slip
it into place. Always insert it all the way until it locks in
place with a little click. If not, it may accidentally fall out
of the tool, causing injury to you or someone around
you.

Installing or removing driver bit or drill bit (Fig. 3)
GEB002-2 CAUTION:
Always be sure that the tool is switched off and the bat-
tery cartridge is removed before installing or removing
the bit.
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the bit in the chuck as far as it
will go. Hold the ring firmly and turn the sleeve clockwise
to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve coun-
terclockwise.
Switch action (Fig. 4)
CAUTION:
Before inserting the battery cartridge into the tool, always
check to see that the switch trigger actuates properly and
returns to the "OFF" position when released.
To start the tool, simply pull the trigger. Tool speed is
increased by increasing pressure on the trigger. Release
the trigger to stop.
Reversing switch action (Fig. 4)
CAUTION:
• Always check the direction of rotation before operation.
• Use the reversing switch only after the tool comes to a
complete stop. Changing the direction of rotation
before the tool stops may damage the tool.
• When not operating the tool, always set the reversing
switch lever to the neutral position.
This tool has a reversing switch to change the direction of
rotation. Set the reversing switch lever to the A side for
clockwise rotation or to the B side for counterclockwise
rotation. When the reversing switch lever is in the neutral
position, the tool will not start even if you pull the trigger.
Overload protector (Fig. 5)
The overload protector automatically cuts out to break
the circuit and the button pops out, whenever heavy work
is prolonged. Wait 20 – 30 seconds before pressing the
restart button to resume operation. Your finger should not
be on the switch trigger when you press the restart but-
ton, however.
Drilling operation
• Drilling in wood
When drilling in wood, best results are obtained with
wood drills equipped with a guide screw. The guide
screw makes drilling easier by pulling the bit into the
workpiece.
• Drilling in metal
To prevent the bit from slipping when starting a hole,
make an indentation with a center punch and hammer
at the point to be drilled. Place the point of the bit in the
indentation and start drilling.
Use a cutting lubricant when drilling metals. The excep-
tions are iron and brass which should be drilled dry.
