Setup & Operation

2.17 Power Feed Operation

See Figure 2-28. 

The power feed system moves the carriage forward and backward by using two

switches on the control panel.

Carriage Feed Rate

The carriage feed rate switch controls the speed at which the carriage travels forward. Turn the
switch clockwise to increase speed. Turn it counterclockwise to reduce speed. 

Carriage Forward and Reverse

The carriage forward/reverse switch controls the direction in which the carriage travels. Turn the
forward/reverse switch upward to move the carriage forward. Turn the switch down to move the
carriage backward.

The middle position (as shown) is the neutral position. The power feed switch is designed to return to
the neutral or "off" position when released from operating in the reverse position. If the switch
remains engaged, manually move the switch to the neutral or "off" position. Repair the drum switch
(

See Section 4.2

)
