Drilling in wood or metal
003222
Use the optional drill chuck assembly. When installing it, refer
to "Installing or removing the bit" described on the previous
page.
Set the change lever so that the pointer points to the
symbol.
You can drill up to 13 mm (1/2") diameter in metal and up to
27 mm (1-1/16") diameter in wood.
CAUTION:
• Never use "rotation with hammering" when the drill
chuck assembly is installed on the tool. The drill chuck
assembly may be damaged. Also, the drill chuck will
come off when reversing the tool.
• 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.
CAUTION:
• Always be sure that the tool is switched off and the
battery cartridge is removed before attempting to
perform inspection or maintenance.

Replacing carbon brushes

001145
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 iden-
tical carbon brushes.
