Recommendations for Tool Operation
• Large (8 mm to 13 mm) holes in steel can be made easier if
a pilot hole (4 mm to 5 mm) is drilled first.
• When drilling, always apply pressure in a straight line with
the bit, but do not push hard enough to stall the motor or
deflect the bit. A smooth even flow of material indicates the
proper drilling rate.
• If drilling thin material or material that is prone to splinter,
use a wood “back‑up” block to prevent damage to
the work piece.
WARNING:
• Do not use this tool to mix or pump easily combustible
or explosive fluids (benzine, alcohol, etc.).
• Do not mix or stir inflammable liquids
labelled accordingly.

The arrow on the mode selector dial 5 must be pointing
at a mode symbol at all times. There are no operable positions
in between. It may be necessary to briefly run the motor after
having changed from 'hammering only' to 'rotary' modes in
order to align the gears.
