Maintenance - Makita DP3002 Instruction Manual

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.
This tool has a reversing switch to change the direction of
rotation. Move the reversing switch lever to the
tion (A side) for clockwise rotation or the
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 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 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 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.
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 perfor-
mance 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, mainte-
