Chip Breaker

The chip breaker is located on the top side of the planer and extends down around the front of the cutterhead. Its function is to prevent tear-out or deep, unregulated gouging as the knives remove material. The chip breaker works by breaking the woodchips as they are being cut by the cutter- head. The chip breaker also deflects and expels the woodchips away from the surface of the board and out of the planer.

TO ADJUST THE CHIPBREAKER:

1.Disconnect the machine from the power source, remove the dust hood and lower the table.

2.Ensure that the knives are properly adjust- ed.

3.Place the gauge block on the table directly under the cutterhead. Using a one millime- ter (0.040") feeler gauge between the gauge block and the cutterhead, raise the table until one of the knives just touches the feeler gauge. Rotate the cutterhead manu- ally to be sure the knife is at bottom dead center.

4.Lock the table by tightening the table lock knobs.

5.Remove the feeler gauge and slide the gauge block under the chip breaker. See Figure 21. The chip breaker should just touch the top of the gauge block. Slide the gauge block to the opposite end of the chip breaker and check it in the same manner.

DO NOT make adjustments while the planer is running. Ensure that the switch is off, power is disconnected and moving parts have stopped before making adjustments. Failure to ensure that power is disconnected could result in serious injury or electrical shock hazard.
