Drilling in metal
To prevent the drill 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
drill 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 drill
bit, decrease the tool performance and shorten the
service life of the tool.
CAUTION:
Hold the tool firmly and exert care
when the drill bit begins to break through the
workpiece. There is a tremendous force exerted on
the tool/drill bit at the time of hole break through.
CAUTION:
A stuck drill 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.
CAUTION:
Always secure small workpieces
in a vise or similar hold-down device.
CAUTION:
If the tool is operated continuously
until the battery cartridge has discharged, allow
the tool to rest for 15 minutes before proceeding
with a fresh battery.

MAINTENANCE

CAUTION:
Always be sure that the tool is
switched off and the battery cartridge is removed
before attempting to perform inspection or
maintenance.
NOTICE:
Never use gasoline, benzine, thinner,
alcohol or the like. Discoloration, deformation or
cracks may result.

Replacing carbon brushes

Check the carbon brushes regularly.
Replace them 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.
