to a complete stop. Never attempt to remove the
cut-off wheel from the cut while the wheel is in
motion otherwise kickback may occur. Investigate
and take corrective action to eliminate the cause of
wheel binding.
h. Do not restart the cutting operation in the
workpiece. Let the wheel reach full speed and
carefully re-enter the cut. The wheel may bind, walk
up or kickback if the power tool is restarted in the
workpiece.
i.
Support panels or any oversized workpiece to
minimize the risk of wheel pinching and kickback.
Large workpieces tend to sag under their own weight.
Supports must be placed under the workpiece near the
line of cut and near the edge of the workpiece on both
sides of the wheel.
j.
Use extra caution when making a "pocket cut" into
existing walls or other blind areas. The protruding
wheel may cut gas or water pipes, electrical wiring or
objects that can cause kickback.
