Operation

CAUTION:

Proper handle pressure during cutting and maximum cutting efficiency can be

determined by the amount of sparks that is produced while cutting. Your pressure on

the handle should be adjusted to produce the maximum amount of sparks. Do not

force the cut by applying excessive pressure on the handle.

Hold the handle firmly. Switch on the machine and wait until the wheel attains full

speed before lowering gently into the cut. When the wheel contacts the workpiece,

gradually bear down on the handle to perform the cut. When the cut is completed,

switch off the machine and wait until the wheel has come to a complete stop before

returning the handle to the fully elevated position.
