Then tighten the grip by turning clockwise at the desired
position. It may be swung 360° so as to be secured at
any position.
NOTE:
•
The depth gauge cannot be used at the position
where the depth gauge strikes against the tool body.
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 reac-
tion 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 revers
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.
Replacing carbon brushes
► 1. Limit mark
Remove and check the carbon brushes regularly.
Replace when they wear down to the limit mark. Keep
the carbon brushes clean and free to slip in the holders.
Both carbon brushes should be replaced at the same
time. Use only identical carbon brushes.
Use a screwdriver to remove the brush holder caps.
Take out the worn carbon brushes, insert the new ones
and secure the brush holder caps.
