Safety
Environment
Avoid use in dangerous environments.
Do not use in rain, damp or wet locations, or in the presence of
explosive atmospheres (gaseous fumes, dust, or flammable mate -
rials). Remove materials or debris that may be ignited by sparks.
Keep work area tidy and well-lit - a cluttered or dark work area may
lead to accidents. Extreme heat or cold may affect performance.
Protect others in the work area and be aware of surroundings.
Provide barriers or shields as needed to protect others from debris
and machine operation. Children and other bystanders should be
kept at a safe distance from the work area to avoid distracting the
operator and/or coming into contact with the machine. Operator
should be aware of who is around them and their proximity. Sup -
port personnel should never stand next to, in front of, or behind
the machine while the machine is running. Operator should look
behind them before backing up.
Do not come within 3 ft. of the machine’s perimeter during
operation.
Guard against electric shock.
Ensure that machine is connected to a properly grounded outlet.
Prevent bodily contact with grounded surfaces, e.g. pipes, radia -
tors, ranges, and refrigerators. When scoring or making cuts,
always check the work area for hidden wires or pipes.
