We recommend changing the headstock oil
before operating the machine further (refer to
Lubrication on Page 46.
Since the head has been moved around for
shipping purposes, you will need to tram it
so that the spindle is perpendicular to the
table. Refer to the Tramming Spindle sec-
tion on Page 58 for detailed instructions.
Inspections &
Adjustments
The following list of adjustments were performed
at the factory before the machine was shipped:
• X-Axis Leadscrew Backlash ........... Page 60
• Gib Adjustments ..............................Page 61
Be aware that machine components can shift
during the shipping process. Pay careful atten-
tion to these adjustments during operation of the
machine. If you find that the adjustments are not
set according to the procedures in this manual or
your personal preferences, re-adjust them.
During the first 16 hours of use, the V-belts
will stretch and seat into the pulley grooves.
The V-belts must be properly tensioned
after this period to ensure proper power
transmission and avoid reducing the life of
the belts. Refer to V-Belt Service on Page 52
for detailed instructions.
