Indicator lamp

2
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 carbon
brushes are nearly worn out to indicate that the tool
needs servicing. After approx. 8 hours of use, the motor
will automatically be shut off.
ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Side grip (auxiliary handle)

CAUTION:
• Always use the side grip to ensure operating safety
when drilling in concrete, masonry, etc.
• When the bit begins to break through concrete or if
the bit strikes reinforcing rods embedded in
concrete, the tool may react dangerously. Maintain
good balance and safe footing while holding the
tool firmly with both hands to prevent dangerous
reaction.
The side grip swings around to either side, allowing easy
handling of the tool in any position. Loosen the side grip
by turning it counterclockwise, swing it to the desired
position and then tighten it by turning clockwise.
