OPERATING INSTRUCTIONS
Installing or removing battery cartridge (Fig. 1)
• 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 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.
• Do not use force when inserting the battery cartridge. If
the cartridge does not slide in easily, it is not being
inserted correctly.
Installing or removing drill bit (Fig. 2)
Important:
Always be sure that the tool is switched off and the battery
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 clock-
wise to tighten the chuck.
To remove the bit, hold the ring and turn the sleeve coun-
terclockwise.
Switch action (Fig. 3)
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. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for counter-
clockwise rotation. When the switch lever is in the neutral
position, the switch trigger cannot be pulled.
Adjusting depth of drilling (Fig. 5)
Install the depth gauge on the tool with the clamp screw
and washer. Adjust the depth gauge to the desired depth
and tighten the clamp screw.

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 centrepunch 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.
CAUTION:
• Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve
to damage the tip of your bit, decrease the tool per-
formance and shorten the service life of the tool.
• There is a tremendous force exerted on the tool/bit at the
time of hole breakthrough. Hold the tool firmly and exert
care when the bit begins to break through the workpiece.
• A stuck bit can be removed simply by setting the reversing
switch to reverse rotation in order to back out. However,
the tool may back out abruptly if you do not hold it firmly.
• Always secure small workpieces in a vice or similar
hold-down device.
• If the tool is operated continuously until the battery car-
tridge has discharged, allow the tool to rest for 15 minutes
before proceeding with a fresh battery.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and the battery
cartridge is removed before carrying out any work on the
tool.

replaced at the same time.
