Workpiece and Work Area Set Up
1. Designate
a work area that is clean and well-lit.
The work area must not allow access by children
or pets to prevent distraction and injury.
2. Route the power cord along a safe route
to reach the work area without creating a
tripping hazard or exposing the power cord to
possible damage. The power cord must
reach the work area with enough extra length
to allow free movement while working.
3. Secure loose workpieces using a vise or clamps
(not included) to prevent movement while working.
4. There must not be hazardous objects, such
as utility lines or foreign objects, nearby that
will present a hazard while working.
5. You must use personal safety equipment including,
but not limited to, ANSI-approved eye and hearing
protection, as well as heavy-duty work gloves.
6. Before beginning work, provide for sparks and
debris that will fly off the work surface.
