Proper handle pressure during
cutting and maximum cutting efficiency can
be determined by the amount of sparks that is
produced while cutting. Do not force the cut
by applying excessive pressure on the handle.
Reduced cutting efficiency, premature wheel wear, as
well as, possible damage to the tool, cut-off wheel or
workpiece may result.
Hold the handle firmly. Switch on the tool and wait until the
