Maintenance; Operation - Makita 6307 Instruction Manual

To stop the tool from the locked position, pull the switch
trigger fully, then release it.
Reversing switch action (Fig. 2)
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
(A side) for clockwise rotation or the
for counterclockwise rotation.
ASSEMBLY
Installing or removing drill bit (Fig. 3)
CAUTION:
• Always be sure that the tool is switched off and
unplugged before installing or removing the bit.
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, remember to return it to the
chuck key holder.

OPERATION

Drilling operation
CAUTION:
• Hold the tool only by the handle when performing an
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
exceptions 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
performance and shorten the service life of the tool.
• There is a tremendous force exerted on the tool/bit at
the time of hole break through. 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
hidden 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 carrying out any work on the tool.
• Never use gasoline, benzine, thinner, alcohol or the
like. Discoloration, deformation or cracks may result.
To maintain product SAFETY and RELIABILITY, repairs,
any other maintenance or adjustment should be
performed by Makita Authorized Service Centers, always
using Makita replacement parts.
