Blade RPM vs. Surface Feet Per Minute (SFPM)
When choosing a blade for your cutting conditions, follow
the blade manufacturer’s recommendations. Match the
blade speed (blade shaft RPM) to the recommended blade
surface feet per minute (SFPM). See Table 8.
RATIO SPEEDS AND BLADE GUARD SIZE
The 4030 Series offers four blade guard sizes (16", 20",
26", 30") that will accommodate most commonly used
diamond blades up to a 30" (762mm). The series further
offers four distinct pulley ratio set-ups that provide specific
blade shaft RPM. Pairing a diamond blade diameter to a
proper ratio speed and blade guard size is imperative.
Additionally, matching up blade diameters with the
appropriate blade guard size is equally as important. See
Table 7.
WARNING
Maximum allowable blade surface feet per minute per
ANSI Standard B.7.1 is 16,000 SFPM.
CHOOSING PROPER BLADE SIZE
CAUTION
Verify the engine start switch is OFF before removing
or installing a blade.
Tighten the 5/8" blade-mounting bolt to 125-175 ft. lbs.
of torque.
