9. Without stopping spindle, use variable-speed
knob to run machine at 1000 and 2000 rpM
for 10 minutes each.
10. press oFF button.
the spindle break-in of the machine is now
complete!
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, allowing the spindle
to run the same amount of time at each speed, until
reaching the maximum spindle speed. Following
the break-in procedure in this progressive man-
ner helps minimize any potential wear that could
occur until lubrication is fully distributed.
you must complete this procedure maintain
the warranty. failure to do this could cause
rapid wear-and-tear of spindle bearings
once they are placed under load.
