Figure 20. Power feed system components.

A.Limit Switch: Stops table movement when either of the switch side plungers are pressed by the limit stops.

B.Limit Stop: Restricts table movement when positioned along the front of the table.

C.Rapid Traverse Button: Moves the table at full speed when it is in motion.

D.Directional Lever: Selects the direction of table movement. The middle position is neutral.

E.Speed Dial: Controls the speed of the power feed. Turning the dial clockwise causes the table to move faster.

F.Circuit Breaker Reset Button: Resets the internal circuit breaker if the unit is overloaded and shuts down.

G.Power Switch: Turns the power feed ON and OFF.

H.X-Axis Ball Handle: Manually moves the table.

I.Graduated Index Ring: Display the distance of table travel in 0.001" increments, with one full revolution equal to 0.200" of table travel.

To confirm the power feed settings that you will be using during operation, we recommend that you use the power feed to move the table through the intended cutting path before starting the spindle rotation and taking the cut

To operate the X-axis power feed:

1.Loosen the X-axis table locks (refer to Figure 19 on Page 30 for locations).

2.Position the limit stops along the front table slot to limit the distance of table travel that is correct for your operation.

Note: Make sure the cap screws firmly lock the limit stops in place when positioned.

3.Turn the speed dial all the way counterclockwise to slowest setting, move the directional lever to neutral (middle) position, then flip the power switch up to turn the unit ON.

4.With your hand poised over the power switch in case you need to suddenly turn the unit OFF, move the directional lever in the desired direction of table travel.

5.Use the speed dial to slowly bring the speed of movement up to the desired rate.

6.When you are finished using the power feed, turn the unit OFF, then rotate the speed dial all the way clockwise and move the directional lever to the neutral (middle) position to avoid unexpected table movement when you next flip the power switch up.
