The 10:1 gearbox attached to the 1 HP Baldor motor (1725 RPM) does not need to be lubricated with gearbox
oil as this is a sealed unit. Should any gear box oil be observed leaking from the shaft seals be sure to call
Barranca Diamond before resuming use of the Fireball Sphere Machine.
The Fenner “flexible" segmented belts can withstand significant strain due to the movement of the grinding
heads during vertical adjustments. Should a belt link break, these links can be readily purchased from most
auto supply stores, Motion Industries, Inc. or McMaster Carr Supply Co. Individual links can be replaced with
use of a wrench or pliers.

TROUBLESHOOTING
Machine Will Not Start
Check power cord and receptacle. Check GFCI switch, push reset button and attempt to restart grinding
heads at variable speed panel. Push ON button and increase RPM by depressing UP arrows. RPM of
grinding heads will increase or decrease each time either the UP or DOWN arrow buttons are depressed
Sphere Materials Locking or Hanging up and Belts Slipping
Stop machine, loosen locking nut on horizontal threaded rod and rotate crank handle clockwise to increase
gap between grinding heads. Sphere material must turn freely between grinding heads for proper operation.
Retighten locking nut once moveable head is correctly adjusted. Horizontal crank handle adjustment can be
performed while grinding heads are turning.
No Water Delivered to Loc-Line Nozzle
Check submersible pump to see if functioning properly. Pump flow should be uninterrupted so a constant
stream of water leaves the tube prior to entering the Loc-Line magnetic base. Flow restrictor (in line crimp)
should be loosened and readjusted to desired flow. Excessive flow is not required, only enough water to flush
grindings/slurry, and cool diamond cups/pads.
