Spindle Break-In - Grizzly G0823 Owner's Manual

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.
Model G0823 (Mfd. Since 2/16)
To perform spindle break-in:
1. Make sure machine has been properly lubri-
cated. Refer to Lubrication on Page 31.
2.
Make sure spindle area is free of obstructions.
3.
Configure V-belts for a spindle speed of
140 RPM. Refer to Changing Spindle Speed
on Page 22.
4. Connect machine to power and run spindle
in forward direction for 10 minutes. Repeat in
reverse direction.
5. Turn machine OFF, allow spindle to come
to a complete stop, then DISCONNECT
MACHINE FROM POWER!
6. Run spindle for 5 minutes in each direction at
each speed listed below (refer to Changing
Spindle Speed on Page 22) and in progres-
sive order.
a. 413 RPM
b. 819 RPM
c. 1450 RPM
d. 2436 RPM
7. Turn machine OFF.
Congratulations! Spindle break-in is now complete.
