Start Up and Spindle
Break-in Procedures
It is essential to closely follow the proper break-in
procedures to ensure trouble free performance.
Complete this process once you have familiarized
yourself with all instructions in this manual.
To begin the start up and break-in procedure:
1. Check
oil levels in the headstock and apron.
Follow all lubrication procedures highlighted
in Lubrication in
the MAINTENANCE sec-
tion on Page 51 of
this manual.
2. Make
sure there are no obstructions around
or underneath the spindle.
3. Turn the spindle O
N/OFF switch to either the
FO
RWARD or REVERSE position and verify
the spindle rota
tes in the proper direction.
4. Set the spindle speed to the lowest RPM,
refer
to Lathe Speeds and Mill Speeds sec-
tions on Pages 34 & 44.
5. Turn
the lathe ON and let it run for a mini-
mum of 10 minutes.
6. Turn
the lathe OFF, change gears to the next
highest RPM and repeat this step for each
RPM setting.
7. Repeat these steps for the mill.
8. Start with the slowest RPM and change V-
belts to
the next highest RPM and repeat this
step for each RPM setting.
Failure to follow start up and spindle break-
in procedures will likely cause rapid deteri-
oration
of spindle and other related parts.
Check all oil levels and lubrication points
before
starting lathe. Excessive
wear will
result if moving parts are not lubricated!
NOTICE
Feed Lever
Figure 36. Feed lever indicated by arrow.
The feed lever allows the power feeding feature
of the lathe to be turned ON and OFF. When
turned to the right, as in Figure 36, the feed
lever
engages power to the leadscrew, providing
power to the apron and cross slide. When turned
to the left, the lever disengages the power feed,
enabling the apron to be fed manually with the
hand crank at the end of the lathe bed. The hand
crank cannot be turned manually unless the feed
lever is turned to the left.
The hand crank has a
clutch so that it will not
turn when the power feed
is used. DO NOT engage
the clutch by hand while
the machine is running.
Injury can occur if this
caution is ignored.
