Power Cord Conversion
USA (117VAC) to European (240VAC) Plug
The speed control electronics used on the SHERLINE Lathe
or Milling Machine will run properly on 240 VAC or 117
VAC, 50 Hz. or 60 Hz.* The electronic circuit automatically
senses the incoming current and switches as needed to
provide 90 VDC to the motor.
The machines are supplied with a USA type plug but can
be easily rewired to accept a European or UK type plug by
attaching the wires using the color codes provided.
*NOTE: A small number of the first DC powered machines
produced had electronic speed controllers that were set up
for 120 (117) volt use only and cannot be converted to use
with 240 volt current. Before making a conversion, check
the product label located on the aluminum frame of the speed
controller to be sure you have a 117V/240V model. Early
models had a small metallic label on the top of the frame
which says in part, “Input Volts: 120VAC.” Later models
have a paper label on the front of the frame which reads,
“KBLC-240DS.” Only units with the 240DS designation
should be converted to 240 volt use.

FIGURE 2A—EARLY MODEL: Small metallic label on top of
Speed Control Frame lists input voltage as 120VAC. DO NOT
ATTEMPT TO CONVERT TO 240 VOLT USE!
FIGURE 2B—CURRENT MODEL: Paper label on end of Speed
Control Frame lists Model Number as “KBLC-240DS”. This
model may be safely converted for use with 240 volt current.
