Chipping/Scaling/Demolition
Set the action mode changing knob to the symbol.
Hold the tool firmly with both hands. Turn the tool on and
apply slight pressure on the tool so that the tool will not
bounce around, uncontrolled. Pressing very hard on the tool
will not increase the efficiency.
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.
Set the action mode changing knob to “rotation only”.
You can drill up to 13 mm (1/2”) diameter in metal and up to
38 mm (1 - 1/2”) diameter in wood. (Note: When using a flat
boring bit.)
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
reversingswitchtoreverserotationinordertobackout.
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.
MAINTENANCE
CAUTION:
• Always be sure that the tool is switched off and
unplugged before attempting to perform inspection or
maintenance.
