Hammer drilling operation
When drilling in concrete, granite, tile, etc., press the action mode changing button on
the
mark side fully. Position the adjusting ring
so
that the pointer points to the
mark. Be sure to use
a
tungsten-carbide tipped bit. To position
a hole
accurately,
start the tool slowly and then increase the drilling speed gradually. Do not apply more
pressure when the hole becomes clogged with chips
or
particles. Instead, run the tool
a t
an idle, then remove the bit partially from the hole. By repeating this several times,
the hole will be cleaned out.
CAUTION :
Pressing excessively on the tool will not speed up the drilling. In fact, this excessive
pressure will only serve to damage the tip of your bit, decrease the tool performance
and shorten the service life of the tool.
