Remove the carbon brush. Check the
length of the brush (11) and replace
if under 6mm. When brushes need
replacement always renew both
brushes, even if one is still more than
6mm long.
Completely screw down the carbon
brush cap. Check that the tool is
working. Before use, allow it run for a
few minutes to enable the brushes to
settle.
WORKING HINTS
FOR YOUR ROTARY
HAMMER DRILL
1. Reduce the pressure on the
drill bit when it is about to break
through. This will prevent the drill
from jamming.
2. When drilling a large hole, first
drill a pilot hole using a smaller
drill bit.
3. Always apply pressure to your
drill bit in a straight line, and if
possible at right angles to the
workpiece.
4. Never change the operating
mode whilst the drill is running.
5. Do not apply excessive pressure
to the tool when chiseling.
Excessive force does not speed
up the work.
