NOTE:
• This table saw is provided with a 10 in. diameter
blade with a body thickness of 1.8 mm (0.07 in.) thick
with a kerf of 2.6 mm (0.1 in.). The riving knife is
2.2 mm (0.09 in.) thick. The blade diameter and the
blade body and kerf dimensions must be properly
matched with the riving knife thickness.
• The maximum radial distance between the riving
knife and the toothed rim of the saw blade is 0.12 in
~ 0.31 in. (3 mm ~ 8 mm)
• The tip of the riving knife shall not be lower than 0.04
in. ~ 0.2 in. (1 mm ~ 5 mm) from the tooth peak.
