Three-Phase Test Run

On the three-phaseunit, after wiring has been completed, you should check that the incoming leads have been connected properly:

1.Connect machine to power source and press the start button. Make sure cutterhead is clear of all obstructions! (See page 21 for more detailed instructions on the switch.)

2.The cutterhead should rotate clockwise as viewed from the front of the machine. If the cutterhead rotation is incorrect, press the stop button and disconnect machine from power.

3.Switch any two of the three leads to the motor, then re-connect to power.

Extension Cords

Make sure your extension cord is in good condition. Always use a cord that is heavy enough to carry the current your product will draw; the cord rating must be suitable for the amperage listed on the machine’s motor plate. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating.

Use the chart in Figure 15 as a general guide in choosing the correct size cord. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.

Adjustments

Disconnect machine from power source before making adjustments.

Tools required for adjustments:

8mm & 12mm wrenches 4mm hex wrench

machinist's protractor or adjustable square steel straight edge

Installing and Adjusting Knives

(Straight Cutterhead only)

Refer to Figure 16.

Use care when working with or around sharp knives. Make sure power to the machine has been disconnected.

When installing new knives, remove only one knife at a time. Clean the knife slot and install the new knife. Adjust and snug new knife in cutterhead before proceeding to next knife.
