Inspections &
Adjustments
The following list of adjustments were performed
at the factory before your lathe was shipped:
• Tailstock alignment (Page 36).
• Compound rest and cross slide backlash
adjustment (Page 57).
• Gib adjustments (Page 58).
Be aware that lathe components can shift during
the shipping process. Pay careful attention to
these adjustments as you test run your lathe.
If you find that the adjustments are not set
according to the procedures in this manual or
your personal preferences, re-adjust them.
Spindle Break-In
To perform spindle break-in:
1.
Successfully complete Test Run procedure
beginning on Page 24.
2.
Use high/low range switch, spindle speed
levers, and spindle direction switch (see
Setting Spindle Speed on Page 42) to
run lathe at 55 RPM for 10 minutes in each
direction (first forward, then reverse).
You must complete this procedure to maintain
the warranty. Failure to do this could cause
rapid wear-and-tear of spindle bearings once
they are placed under load.
The spindle break-in procedure distributes
lubrication 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 bearings. 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
incrementally 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 manner helps minimize any potential
wear that could occur until lubrication is fully
distributed.
3.
Turn spindle direction switch to OFF
position. Shift spindle speed levers into
position for 200 RPM, then run lathe for 5
minutes in each direction.
4.
Repeat
Step 3 for following speeds,
progressing from lower to higher RPMs:
• 410 RPM
•
600 RPM
• 1100 RPM
• 2200 RPM
5.
Turn lathe OFF.
Congratulations! The Spindle Break-In is
complete. We recommend changing the headstock
and gearbox oil before operating the machine
further (refer to Lubrication on Page 52).
