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 force exerted on the tool/
bit at the time of hole break through. 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.
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.
Indicator lamp

► 1. Power-ON indicator lamp (green) 2. Service
indicator lamp (red)
The green power-ON indicator lamp lights up when the
tool is switched ON. If the indicator lamp is lit but the
tool does not start, the carbon brushes may be worn
out, or the electric circuit or the motor may be defective.
If the indicator lamp does not light up and the tool does
not start, the ON/OFF switch or the mains cord may be
defective.
The red service indicator lamp lights up when the tool is
excessively loaded. Continued operation under such a
condition will result in a failure or breakage of the tool.
At this time, cool down the tool by running the tool under
no load.
Cleaning vent holes
The tool and its air vents have to be kept clean.
Regularly clean the tool's air vents or whenever the
vents start to become obstructed.
