Maintenance - DeWalt D28700 Instruction Manual

PROCEDURE FOR PERMANENT MOUNTING
1. Mark through the holes in the base (D) and drill two holes,
5/16" (7.94 mm) diameter, through the mounting surface.
2. Use 1/4" (6.35 mm) fasteners to securely mount base to
mounting surface.
CRADLE MOUNTING (FIG. 9)
1. Cut two boards approximately
20" long x 2" high x 4" wide
(508 x 50.8 x 101.6 mm).
2. Place the chop saw at
desired work location.
3. Place boards tightly along
side and nail to work surface.
Operation Tips for
More Accurate Cuts
• Allow the wheel to do the
cutting. Excessive force will
cause the wheel to glaze reducing cutting efficiency and/or to
deflect causing inaccurate cuts.
• Properly adjust fence angle.
• Make sure material is laying flat across base.
• Properly clamp material to avoid movement and vibration.
