PM-1440GS v3 2020-10
POWER CONNECTION
As shipped. the PM-1440GS is set for 220 V. If your supply is
nominally 240 V, it may be desirable to alter connections to the
24V transformer in the electrical box.
Read Initial Checks, next page, before connecting power
If the lathe did not come with a pre-installed power cord, con-
nect to the power source using 12 AWG (minimum) 3-wire cord
through a strain relief bushing sized for the electrical box ports.
Depending on installed options and other factors, the entry
point shown in Figure 1-6 may not be available. Connect the
ground wire (PE) to the grounding plate at bottom left. Connect
L1, L2 to the left-most two terminals on the bottom terminal
strip (the wires may be marked L, N instead of L1, L2).

LEVELIN
G
Make sure the lathe is in its permanent location. The following
procedure ensures that the lathe bed is in the same state as it
was when the lathe was checked for accuracy in manufacture
— level from end to end along the bed, and from front to back.
In other words, no warping.
Make sure all leveling mounts and/or shims are
properly
weight bearing
, firmly in contact with the floor. Check and ad
-
just level from end to end using a precision machinist’s level, if
available. If not, use the most reliable level on hand. Check and
adjust level front-to-back across the bed using a matched pair
of spacer blocks to clear the Vee tenons on the bed ways. The
blocks need to be at least 1/4 inch thick, ground or otherwise
accurately dimensioned. Alternatively, check for level on the
ground surface of the cross slide as the carriage is traversed
from end to end. See also "Aligning the Lathe" in Section 4.
FOOTBRAKE & BELT COVER INTERLOCKS
The lathe will not run if the belt cover is removed, allowing the
interlock switch to open, Figure 1-4. The same applies if the
footbrake switch fails to close when the foot treadle is released
(brake OFF). Both switches should be checked before power
is connected.

CLEANUP
Metal surfaces may have been protected by thick grease and/
or paper. Carefully remove these using a plastic paint scraper,
disposable rags and a light-oil such as WD-40.
CHIP TRAY
Check that the chip tray, Figure 1-5, can be pulled forward
without snagging coolant hoses and worklight wiring. Use ca-
ble ties if necessary.
