Coring Operation
A. Place water collecting ring in place as necessary.
B. Make sure the drill stand is properly secured to the work surface. If not
follow the instructions provided in the drill stand manual.
C. Check that the spindle speed is at the correct setting. If not adjust as
instructed in the "setup" section.
NOTE: The motor must be OFF and the spindle must not be in motion when
changing the speed setting. Failure to follow these conditions can result in gear
or motor damage.
D. Turn the water valve on the drill motor on. There must be sufficient flow of
water to the core bit.
E. Activate the drill and allow the spindle to achieve peak RPM before letting
the bit engage the work surface.
F.
During the initial portion of the coring process, the bit may wander. Apply a
light amount of force at first until the bit appears to have cored out a groove.
G. While coring do not apply too much downward force. Refer to the motor
load ammeter as reference. To achieve constant even and sufficient force, keep
the yellow LED lit. Do not allow the red LED to become lit.
WARNING: Warning do not core upwards!
