MACHINE SET-UP
Drill Spindle Speed:
• Depending on Drill Motor model, some units may have
two (Low, High) or three (Low, Medium, High) spindle
speeds. This allows Diamond Drill Bit Diameter to run
at an optimized rotational speed that increases bit life
and performance. See Motor Operation Manual for
information on “Speed Select Switch” operation.
Refer to motor operation manual to
determine appropriate speed (RPM) to
run the selected bit. Change “Speed
Select Switch” on motor
(if equipped)
to the appropriate speed.
