Drilling Operation - Makita DP3003 Betriebsanleitung

Hook
► Fig.3: 1. Hook
► Fig.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: 1. Side grip (auxiliary handle) 2. Teeth 3. Protrusion
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
CAUTION:
Always be sure that the tool is
switched off and unplugged before installing or
removing the drill bit.
For model DP4000, DP4002
► Fig.6: 1. Drill chuck 2. Chuck key
To install the drill bit, place it in the drill 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 drill bit, turn the drill chuck key counterclock-
wise in just one hole, then loosen the chuck by hand.
After using the chuck key, be sure to return it to the original position.
For model DP3003, DP4001, DP4003
► Fig.7: 1. Sleeve 2. Ring
Hold the ring and turn the sleeve counterclockwise to
open the chuck jaws. Place the drill bit in the drill chuck
as far as it will go. Hold the ring firmly and turn the
sleeve clockwise to tighten the chuck.
To remove the drill bit, hold the ring and turn the sleeve
counterclockwise.
Depth gauge
Optional accessory
The depth gauge is convenient for drilling holes of uniform
depth. Loosen the side grip and insert the depth gauge
into the hole on the side grip. Adjust the depth gauge to the
desired depth and tighten the side grip firmly.
► Fig.8: 1. Depth gauge
NOTE: Make sure that the depth gauge does not
touch the main body of the tool when attaching it.
OPERATION
Holding tool
Holding against a stud
► Fig.9: 1. Reaction 2. Reverse 3. Forward
Holding against a floor
► Fig.10: 1. Forward 2. Reaction
Always use the side grip (auxiliary handle) and firmly
hold the tool by side grip and switch handle during
operations.
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 reac-
tion if the drill bit should bind. When reversing, brace
the tool to prevent a clockwise reaction. If the drill 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 drill bit into
the workpiece.
Drilling in metal
To prevent the drill 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
drill 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 drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill 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.
CAUTION:
Always secure workpieces in a
vise or similar hold-down device.
CAUTION:
Avoid drilling in material that you
suspect contains hidden nails or other things that
may cause the drill bit to bind or break.
