Read and understand the entire contents of this
manual before attempting set-up or operation.
Failure to comply may cause serious injury.
Confirm that all suspension equipment is properly
rated and in good condition for lifting lathe. Do not
allow anyone beneath or near load while lifting.
8. The lathe can be placed upon the cast iron leveling
pads under each foot hole, and adjusted using the
adjusting bolts with hex nuts. Or, it may be secured
to the floor using bolts placed head-down in the con-
crete, and using shims where needed to level the
machine. Refer to Figure 1 for mounting hole dimen-
sions.
7.1 LEVELING THE LATHE
It is imperative that the lathe be on a level plane; that is,
where headstock and tailstock center points remain aligned
throughout the tailstock travel, with the bed ways absent of
twist and thus parallel to the operational center line.
A lathe which is not properly leveled will be inaccurate, pro-
ducing tapered cuts. Also, the center point of the tailstock
will vary as it is positioned along the bed, thus requiring
constant readjustment.
9. Use a machinist’s precision level on the bed ways
both front to back and side to side, as shown in Fig-
ure 7. Take the reading in one direction every ten
inches. Make sure the ways are clean and free of any
debris before placing a level upon them.
10. Deviation over bed length (see Figure 7):
(a) Maximum 0.02/1000mm
(b) Maximum 0.04/1000mm

7.0 INSTALLATION
1. Finish removing all crate material from around lathe.
2. Unbolt lathe from shipping pallet.
3. Choose a location for the lathe that is dry and
has sufficient illumination (consult OSHA or ANSI
standards for recommended lighting levels in
workshop environments).
4. Allow enough room to service the lathe on all four
sides, and to load and off-load work pieces. In
addition, if bar work is to be performed, allow enough
space for stock to extend out the headstock end. If
used in production operations, leave enough space
for stacking unfinished and finished parts.
5. The foundation must be solid to support the weight of
the machine and prevent vibration, preferably a solid
concrete floor.
6. The lathe’s center of weight is near the headstock.
Before lifting, move the tailstock and the carriage to
the right end of the bed and lock them.
7. With properly rated lifting equipment, slowly raise
lathe off shipping pallet. (see Figure 6). Do not lift
lathe by the spindle.
