OPERATION
Drilling operation
Drilling in wood
When drilling in wood, best results are obtained with wood drills equipped with a
guide screw. The guide screw makes drilling easier by pulling the bit into the work-
piece.
Drilling in metal
To prevent the bit from slipping when starting a hole, make an indentation with a cen-
terpunch and hammer at the point to be drilled. Place the point of the bit in the inden-
tation and start drilling.
Use a cutting lubricant when drilling metals. The exceptions are iron and brass which
should be drilled dry.
CAUTIO N :
Pressing excessively on the tool will not speed up the drilling. In fact, this excessive
pressure will only serve 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 though the workpiece.
Always grip the small workpiece firmly with
a
vise or a holding means.
A stuck bit can be removed simply by setting the reversing switch to reverse rotation
in order to back out. However, the tool will pull away easily unless you hold it firmly
before starting the tool.
MAINTENANCE
CAUTIO N :
Always be sure that the tool is switched off and unplugged before attempting to perform

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.
