Preventative Maintenance

1.The gears and bearings in the ram, spindle, and housing assemblies should be regreased every 6 months or 500 hours. This procedure must be ac- complished by a trained technician.

2.After each servicing, measure the spindle speed

(rpm – revolutions per minute) at 12 gpm/45 lpm in- put. The nominal speed is 4000, not to exceed 6000 rpm. This procedure must be accomplished by a trained technician.

3.Inspect the spindle and drive flange for signs of wear or damage. Run out should not exceed .004 in./.1 mm TIR on threads or .002 in./.05 mm TIR on arbor diameters and faces.

4.Check hoses and fittings weekly for any evidence of leakage, cover wear, cracking or cuts. If any of these defects are found, discontinue use of the tool imme- diately and have the defects repaired or replaced by a trained technician.
