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 spindle bearing break-in proce-
dure to prevent rapid wear and tear of spin-
dle components once drill press is placed
into operation.
Model T33901/T33902 (Mfd. Since 07/23)
To perform spindle break-in:
Make sure spindle area is free of obstructions.
1.
Configure V-belts for a spindle speed of
2.
340 RPM. Refer to Changing Spindle Speed
on Page 28.
Connect machine to power and run spindle
3.
for 10 minutes.
Turn machine OFF, allow spindle to come
4.
to a complete stop, then DISCONNECT
MACHINE FROM POWER!
Configure V-belts for spindle speed of 530
5.
RPM (refer to Changing Spindle Speed on
Page 28), then connect machine to power.
Run spindle for 5 minutes at 530 RPM.
6.
Repeat Steps 4–6 for each speed listed
7.
below in progressive order.
a. 1380 RPM
b. 1860 RPM
c. 2860 RPM
Turn machine OFF.
8.
Congratulations! Spindle break-in is now complete.
