Maintenance - Makita DP3002 Instruction Manual

Reversing switch action (Fig. 4)
CAUTION:
• Always check the direction of rotation before opera-
tion.
• 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.
This tool has a reversing switch to change the direc-
tion of rotation. Move the reversing switch lever to the
position (A side) for clockwise rotation or the
position (B side) for counterclockwise rotation.
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.
Depth gauge (optional accessory) (Fig. 6)
The depth gauge is convenient for drilling holes of
uniform 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 gear
housing.
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 ham-
mer 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
exceptions are iron and brass which should be drilled
dry.

Holding tool (Fig. 7 & 8)
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.
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 performance 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 vise or similar
hold-down device.
Hook (Fig. 9 & 10)
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 position
by following the above procedures in reverse.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs,
maintenance or adjustment should be carried out by a
Makita Authorized Service Center.
