BEFORE EACH USE:

Inspect your saw

DISCONNECT THE SAW. To avoid injury from accidental starting, unplug the saw, push the switch "OFF" and lock the switch before changing the setup or removing covers, guards, or blade.

Inspect your workpiece

Make sure there are no nails or foreign objects in the part of the workpiece to be cut.

Use extra caution with large, very small or awkward workpieces:

Never use this tool to cut piecestoo small to hold by hand.

Use extra supports (tables, saw horses, blocks, etc.) for any workpieces large enough to tip when not held down to the table top.

NEVER use another person as a substitute for a table extension, or as additional support for a workpiece or to help feed, support or pull the workpiece.

When cutting irregularly shaped workpieces, plan your work so it will not pinch the blade. A piece of molding, for example, must lay flat or be held by a fixture or jig that will not let it twist, rock or slip while being cut.

Properly support round material such as dowel rods, or tubing. They have a tendency to roll during a cut, causing the blade to "bite". To avoid this, always use a " V block.

Cut only one workpiece at a time.

Clear everything except the workpiece and related support devices off the table before turning the saw on.

Plan the way you will hold the workpiece from start to finish

Do not hand hold pieces so small that your fingers will go under the work hold-down. Use jigs or fixtures to hold the work and keep your hands away from the blade.

Before freeing any jammed material:

Push switch "OFF".

Lock the switch.

Unplug the saw.

Wait for all moving parts to stop.

When backing out the workpiece, the blade may bind in the kerf (cut). This is usually caused by sawdust clog- ging up the kerf. If this happens:

Push switch "OFF".

Lock the switch.

Unplug the saw.

Wait for all moving parts to stop.

Remove the blade from the blade holders.

Remove workpiece with blade from the table. Remove blade from workpiece.

Push switch "OFF".

Before removing loose pieces from the table, turn saw off and wait for all moving parts to stop.
