button.
7. Rotate variable-speed knob to 100 RPM
and high/low gearbox knob to high
"H".
8. Press
ON
button.
9. Run machine for a minimum of 10
minutes.
10. Without stopping spindle, use variable-
speed knob to run machine at 1000
and 2000 RPM for 10 minutes each.

The spindle break-in of the machine is now
complete!
To perform spindle break-in procedure, do these steps:
1. Successfully complete Test Run procedure beginning
on
Page 19.
2. Rotate variable-speed knob to 50 RPM and high/low
gearbox knob to low "L".
3. Press
ON
button.
4. Run spindle for minimum of 10 minutes.
5. Without stopping spindle, use variable-speed knob
to run machine at 500 and 1000 RPM for 10 minutes
each.
The spindle break-in procedure distributes lubrication
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 bearings. 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 incrementally increase spindle speeds
and repeat this process at each speed until reaching
the maximum spindle speed. Following the break-in
procedure in this progressive manner helps minimize any
potential wear that could occur before lubrication is fully
distributed.
You must complete this procedure to
maintain the warranty. Failure to do
this could cause rapid wear-and-tear of
spindle bearings once they are placed
under load.
