POCKET CUTS (PLUNGE CUTTING)

A pocket cut is one which must be made inside
the area of the workpiece and not starting from
the edge. Mark the area clearly with lines on all
sides. Start near the corner of one side and
place the front edge of the saw base firmly on
the workpiece. Hold the saw up so that the
blade clears the material. Confirm that you have
adjusted the blade properly for the depth of cut.
Push the telescoping guard lever all the way	Fig. 21
back so the blade is exposed (Fig. 21).

Keep your hands and fingers away from the blade.

Start the motor and lower the blade into the work. After the blade has cut through, and the base rests flat on the work, follow the line to the corner.

Let the saw come to a complete stop before removing it from the workpiece.

Use a keyhole or bayonet saw to cut clean corners.

MAINTENANCE

KEEP TOOL CLEAN

Periodically blow out all air passages with dry compressed air. All plastic parts should be cleaned with a soft damp cloth. NEVER use solvents to clean plastic parts. They could possibly dissolve or otherwise damage the material.

Wear ANSI Z87.1 safety glasses while using compressed air.

FAILURE TO START

Should your tool fail to start, check to make sure the prongs on the cord plug are making good contact in the outlet. Also, check for blown fuses or open circuit breakers in the line.
