Set the mode adjustment knob to ‘hammer-drilling’ position for
concrete and masonry drilling operations.
Always operate the tool using both the handles. Always hold the
product perpendicular to the point to be drilled.
Always place the drill tip directly on the point to be drilled first
and then switch the product on.
Pre-drill larger holes with a small diameter drill bit first. Doing so
makes drilling with a larger diameter drill bit easier. Do not
‘always’ drill at top speed.
Switch off the tool when work is finished before unplugging.
Set the mode adjustment knob to the ‘Hammering only’ position
for chisel work using hammering. Follow the same procedures
mentioned above.
GENERAL OPERATION
HAMMER-DRILLING
NOTE:
Always switch the product off, disconnect the product from the
power supply and let the product cool down before performing
inspection, maintenance and cleaning work! Only perform repairs and
maintenance work according to these instructions! All further works
must be performed by a qualified specialist!

HAMMERING
WARNING!
Applying force more than necessary will not only
accelerate the work at all, but will worsen the tip edge of the drill bit
and reduce the service life of the rotary hammer in addition.
Always apply pressure to your drill bit in a straight line, and if
possible at right angles to the work piece.
Never change the operating mode while the rotary hammer is still
running.
