REMOVAL OF LIFT BAIL
1. Remove the main input supply power to the
machine.
2. With the 5/16” nut driver, remove the case
top and sides.
3. Remove the two fiber baffles from the left
and right sides of the choke. See Figure
F.33.
4. If the optional Pocket Amptrol diodes are
installed, label and disconnect the neces-
sary leads for removal of the lift bail. One
lead is on the shunt, and one lead is on the
optional polarity switch. Label and cut leads
#218 and #219 from the sensing resistor.
See the Wiring Diagram. These leads will
have to be resoldered upon reassembly.
5. Remove resistor R3 (40 ohms, 100 watts).
6. Using the 9/16” socket wrench, remove the
four bolts (left and right) mounting the lift bail
to the transformer top and bottom irons.
7. Using the 9/16” socket wrench, remove the
four bolts, flat washers, and lock washers
mounting the lift bail assembly to the base of
the machine.
The transformer and choke assembly is now
loose and free to slide or “tip” on the base of the
machine.
8. Remove the lift bail by lifting straight up and
clear from the machine. Clear any remaining
leads necessary for lift bail removal.
