Operation; Maintenance - Makita DP3002 Betriebsanleitung

Reversing switch action (Fig. 2)
This tool has a reversing switch to change the rotational
direction. Move the reversing switch lever to the D
position (A side) for clockwise (forward) rotation or the
E position (B side) for counterclockwise (reverse) rota-
tion.
CAUTION:
• Always check the rotational direction before operation.
• Use the reversing switch only after the tool comes to a
complete stop. It will damage the tool to change the
rotational direction before the tool stops.
Hook (Fig. 3 & 4)
When using the hook, pull it out in "A" direction and then
push it in "B" direction to secure in place.
When not using the hook, return it back to its initial posi-
tion by following the above procedures in reverse.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing side grip (auxiliary handle) (Fig. 5)
Always use the side grip to ensure operating safety.
Install the side grip so that the teeth on the grip fit in
between the protrusions on the tool barrel.
Then tighten the grip by turning clockwise at the desired
position. It may be swung 360° so as to be secured at
any position.
Installing or removing drill bit
For Model DP3003, DP4001, DP4003 (Fig. 6)
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.
For Model DP3002, DP4000, DP4002 (Fig. 7)
To install the bit, place it in the chuck as far as it will go.
Tighten the chuck by hand. Place the chuck key in each
of the three holes and tighten clockwise. Be sure to
tighten all three chuck holes evenly.
To remove the bit, turn the chuck key counterclockwise
in just one hole, then loosen the chuck by hand.
After using the chuck key, be sure to return to the original
position.
Depth gauge (optional accessory) (Fig. 8)
The depth gauge is convenient for drilling holes of uni-
form depth. Loosen the side grip and insert the depth
gauge into the hole in the side grip. Adjust the depth
gauge to the desired depth and tighten the side grip.
NOTE:
• The depth gauge cannot be used at the position where
the depth gauge strikes against the tool body.

OPERATION

Holding tool (Fig. 9 & 10)
Always use the side grip (auxiliary handle) and firmly
hold the tool by side grip and switch handle during opera-
tions.
When drilling a large hole with a hole saw, etc., the side
grip (auxiliary handle) should be used as a brace to
maintain safe control of the tool.
Grasp the rear handle and the front grip firmly when
starting or stopping the tool, since there is an initial and
final reaction.
When drilling action is forward (clockwise), the tool
should be braced to prevent a counterclockwise reaction
if the bit should bind. When reversing, brace the tool to
prevent a clockwise reaction. If the bit must be removed
from a partially drilled hole, be sure the tool is properly
braced before reversing.
Drilling operation
Drilling in wood
When drilling in wood, the 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.
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 perfor-
mance and shorten the service life of the tool.
• There is a tremendous twisting 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 vise or similar
hold-down device.
• Avoid drilling in material that you suspect contains hid-
den nails or other things that may cause the bit to bind
or break.

MAINTENANCE

CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
carbon brush inspection and replacement, any other
maintenance or adjustment should be performed by
Makita Authorized Service Centers, always using Makita
replacement parts.
