1. Set mode switch to Drill.
2. Set spindle speed to 115 RPM (see Spindle
Speed on Page 26 for details). Run for 10
minutes in each direction of rotation (FWD
and REV).

To perform spindle break-in procedure:
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

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 and repeat this pro-
cess 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.

cause rapid wear-and-tear of spindle bear-

After completing the spindle break-in procedure,
we recommend changing the headstock oil to
flush any small particles that may be present in
the headstock from the manufacturing process.
