Operation
Turn the machine on and wait until the blade attains
full speed. Then press the shoe against the workpiece
and apply pressure to cut the workpiece.
CAUTION:
Excessive pressure that causes bending or twisting of
the blade may snap it.
Metal cutting (Fig. 6)
Always use a suitable coolant (cutting oil) when
cutting metal. Failure to do so will cause significant
blade wear.
