hold the tool by both side grip and switch handle during
operations. Turn the tool on and apply slight pressure on
the tool so that the tool will not bounce around,
uncontrolled. Pressing very hard on the tool will not
increase the efficiency.

unplugged before attempting to perform inspection
or maintenance.

the like. Discoloration, deformation or cracks may
