Blow-out bulb (optional accessory)
After drilling the hole, use the blow-out bulb to clean the dust
out of the hole.
Drilling in wood or metal
Use the optional drill chuck assembly. When installing it, refer
to “Installing or removing the bit” described on the previous
page.
You can drill up to 13 mm (1/2”) diameter in metal and up to
24 mm (15/16”) diameter in wood.
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.
• Always secure small workpieces in a vise or similar hold-
down device.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
Replacing carbon brushes
When the resin insulating tip inside the carbon brush is
exposed to contact the commutator, it will automatically shut
off the motor. When this occurs, both carbon brushes should
be replaced. 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.
