• Reduce the pressure on the drill bit when it is
about to break through. This will prevent the
drill from jamming.
• When drilling a large hole, first drill a pilot hole
using a smaller drill bit.
• Always apply pressure to your drill bit in a
straight line, and if possible at right angles to
the workpiece.
• Never change the operating mode whilst the
drill is running.
• Do not apply excessive pressure to the tool
