Spindle Break-In
The spindle break-in procedure distributes lubri- cation throughout the bearings to reduce the risk of early bearing failure if there are any "dry" spots or areas where lubrication has settled in the bear- ings. You must complete this procedure before placing operational loads on the spindle for the first time when the machine is new or if it has been sitting idle for longer than 6 months.
Always start the spindle break-in at the lowest speed to minimize wear if there are dry spots. Allow the spindle to run long enough to warm up and distribute the bearing grease, then incremen- tally increase spindle speeds, allowing the spindle to run the same amount of time at each speed, until reaching the maximum spindle speed. Following the break-in procedure in this progressive man- ner helps minimize any potential wear that could occur until lubrication is fully distributed.
You must complete this procedure to main- tain the warranty. Failure to do this could cause rapid wear-and-tear of spindle bear- ings once they are placed under load.
To perform spindle break-in procedure:
1.Rotate variable-speed knob to 50 RPM and high/low gearbox knob to low "L".
2.Press ON button.
3.Run spindle for minimum of 10 minutes.
4.Without stopping spindle, use variable-speed knob to run machine at 500 and 1000 RPM for 10 minutes each.
5. Press OFF button.

6.Rotate variable-speed knob to 100 RPM and high/low gearbox knob to high "H".
7.Press ON button.
8. Run machine for a minimum of 10 minutes.
9. Without stopping spindle, use variable-speed knob to run machine at 1000 and 2000 RPM for 10 minutes each.
10. Press OFF button.
The spindle break-in of the machine is now complete!
Inspections &
Adjustments
The following adjustments were performed at the factory before the machine was shipped:
•Gib Adjustments.............................. Page 34
