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 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.
Complete the spindle bearing break-in pro-
cedure to prevent rapid wear and tear of
spindle components once the drill press is
placed into operation.
DO NOT perform this procedure indepen-
dently of the Test Run section. The drill
press could be seriously damaged if the
controls are set differently than instructed
in that section.

To perform spindle break-in:
1.
Make sure machine has been properly lubri-
cated. Refer to Lubrication on Page 29.
2.
Make sure spindle area is free of obstruc-
tions.
3.
Set spindle speed to the lowest RPM. Refer
to Speed Changes on Page 21.
4.
Run spindle for 5 minutes in each direction
at each speed listed below (refer to Speed
Changes on Page 21) and in progressive
order.
a. 140 RPM
b. 413 RPM
c. 819 RPM
d. 1450 RPM
e. 2436 RPM
5.
Turn machine OFF.
Congratulations! Spindle break-in is now complete.
