OPERATION
Holding tool
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 performance 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 con-
tains 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 attempting to perform inspec-
tion 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 or Factory Service Centers, always
using Makita replacement parts.
