Drilling operation
*Drilling in wood
When drilling holes in the wood, use a wood drill with a guide screw. The guide screw
makes it bore naturally by itself,
so
you do not need to apply any pressure to the tool.
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.
*Drilling in metal
CAUTION:
*Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pres-
sure 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.
*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
CAUTION:
Always be sure that the tool is switched off and unplugged before attempting to perform
inspection or maintenance.
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.
