Test Run; Spindle Break-In - Grizzly G0779 Owner's Manual

Test Run

Once assembly is complete, test run the machine
to ensure it is properly connected to power and
safety components are functioning correctly.
If you find an unusual problem during the test run,
immediately stop the machine, disconnect it from
power, and fix the problem BEFORE operating the
machine again. The Troubleshooting table in the
SERVICE section of this manual can help.
Serious injury or death can result from
using this machine BEFORE understanding
its controls and related safety information.
DO NOT operate, or allow others to operate,
machine until the information is understood.
DO NOT start machine until all preceding
setup instructions have been performed.
Operating an improperly set up machine
may result in malfunction or unexpect-
ed results that can lead to serious injury,
death, or machine/property damage.
Make sure headstock has proper amount of
oil before performing Test Run and Spindle
Break-In. Otherwise, headstock compo-
nents may be damaged and void warranty.
Refer to Page 32 for detailed instructions.
To test run machine:
1. Clear all setup tools away from machine.
2. Connect machine to power supply.
3. Set spindle speed to 90 RPM (see Page 25).
4. Rotate spindle switch to RIGHT to turn
machine ON. Verify motor operation, then
turn machine OFF. The motor should run
smoothly and without unusual problems or
noises. Repeat with switch set to LEFT.

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.
Do not leave drill press unattended dur-
ing Spindle Break-In procedure. If your
attention is needed elsewhere during this
procedure, turn machine OFF and restart
procedure later from the beginning.
To perform spindle break-in procedure:
1.
Make sure spindle is completely stopped,
then set spindle speed to 90 RPM (refer to
Page 25 for detailed instructions).
2.
Run machine for a minimum of 5 minutes in
each spindle direction.
3. Repeat Step 2 for each of the spindle speeds.
4. Change headstock oil (refer to Page 31 for
detailed instructions).
Congratulations! The test run and spindle break-in
are now complete!
