GRINDER SPECIFIC WARNINGS
•
Always match collet size with accessory shank size.
•
Always insert tool shank no less than 10 mm in the
collet. Tighten Collet Nut securely to prevent
accessory from working out during operation of the
Grinder. Check tightness of Collet Nut before
operating the Grinder. Pay particular attention to
the fact that allowed speed of a mounted point is
lowered when the length of the shaft is increased
between end of collet and mounted point (overhang).

After each two hours of operation, if an air line lubricator is
not used, inject 1/2 to 1 cc of Ingersoll–Rand No. 10 Oil into
the Air Inlet.
After each eight hours of operation, inject approximately
3 cc of Ingersoll–Rand No. 67 or Ingersoll–Rand No. 77

will cause grease to work out around the Arbor.
