KICKBACK may occur. Investigate and take
corrective action to eliminate the cause of blade
binding. Wet lumber, green lumber or pressure-
treated lumber and most plastics require special
attention during cutting operation to prevent
KICKBACK. Avoid cutting nails. Inspect for and
remove all nails from lumber before cutting.
When restarting a saw in a workpiece, center
the saw blade in the kerf and check that saw
teeth are not engaged into the material. If saw
blade is binding, it may walk up or KICKBACK from
the workpiece as the tool is restarted.
Support panels to minimize the risk of blade
pinching and KICKBACK. Large panels tend to sag
under their own weight. Supports must be placed
under the panel on both sides, near the line of cut and
near the edge of the panel.
Do not use dull or damaged blade. Unsharpened
or improperly set blades produce narrow kerf
causing excessive friction, blade binding and
KICKBACK.
Use extra caution when making a "Pocket
Cut" into existing walls or other blind areas.
The protruding blade may cut objects that can
cause KICKBACK.
