ELECTRICAL CONNECTIONS
The machine is wired at factory - - merely connect
power supply to line leads in junction box on back
of headstock cabinet. IMPORTANT: To reverse ro-
tation of motor interchange any two line leads - - see
WIRING INSTRUCTIONS .
Before connecting motor, make sure chat voltage and
other current requirements of the motor correspond
with your power supply. If there is any question,
verify your current and voltage by calling your power
company.

Use anchor bolts to secure : fathe to concrete floor - -
use lag screws to secure lathe to wood floor - - refer
to figure 2.
With a hoist or lift, lower the lathe into position and
mark the four leveling screw locations. DO NOT
LOWER LEVELING SCREW PADS.
Lift machine out of the way, drill holes for anchor
nuts and install anchor nuts - - for lag screws drill
pilot holes.
Position and lower machine. Turn leveling screws
until no portion of the lathe cabinet touches the
floor -- shim under pads, if necessary.
Start anchor bolts or lag screws - - DO NOT tighten
until lathe is level - - see Leveling Instructions.
LEVELING
The lathe should be kept perfectly level at all times.
- When carelessly mounted, the be.d may become twist-
ed. Even a slight amount of twist will move centers
out of alignment and result in inaccurate work and
excessive wear. Make it a habit · co regularly check
the level of the bed.
THIS IS IMPORTANT:
Use one precision level at lease 6
11
long -- level
should show a distinct bubble movement when a
.003" shim is placed under one end .
Clean the bed ways thoroughly .
Figure 3
L First level bed longitudinally , compensate for
variations of bubble readings by turning the leveling
screws on the cabinet base until bed is level - - refer
to Figure 3 for level positions.
2. Next level both ends of the bed. The headstock
and the tailstock - - muse be checked with the level
placed at right angles to the bed. Refer to Figure 3,
· Use a square to align the level. Do not tum lev el
end for e nd .
-- ·· Level reading at headstock and cailstock must be
identical. Compensate for variations of bubble read-
ings by turning the leveling screws until lathe is
level.
4.1
NOTE: Avoid excessive adjustment of leveling
screws by inserting shims between pads and floor.
3. Tighten the four anchoring bolts not more than
finger-tight, or until the lock washers start to com-
press · - lag screws should be tightened, then backed
off about one-quarter turn.
4. Recheck the level of the lathe - • unequal tighten- ·
ing of anchoring bolts may have pulled che bed out
of level. Recheck leveling in 5 days.
Check level of bed at frequent intervals. Chatter - -
turning taper - - boring taper . • facing convex or
concave is the general result of an improperly leveled
lathe.
