PROCEDURE

Bridgeport Mill Sketch.png

HIGH-LOW RANGE SWITCH: High-Low Range Switch “A”, is a motor reversing switch. When the attachment is in direct drive (HIGH SPEED), the motor and spindle are turning in a clockwise direction as viewed from the top of machine. When the attachment is in “Back Gear” (LOW SPEED), the spindle will run backwards (counter-clockwise) unless the motor direction is reversed by moving switch to “Low”. The back gear lever is marked Hi-Lo. This will indicate the proper switch position. They should be positioned alike or the spindle will run backwards. - NOTE - Spindle should run in clockwise position.

VARIABLE SPEED DIAL Variable Speed Dial "B", visibly indicates, in windows, the speed range that the machine is operating in, 60 to 500 low range, 500 to 4200 high range.
