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.
0
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 indenta-
tion
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.
*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.
The tool will stop when the carbon brushes wear to
a
certain length.
When this occurs, both carbon brushes should be replaced.
To
maintain product SAFETY and RELlABl LITY, 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.
