TROUBLESHOOTING

If you follow the instructions in this book, and adequately maintain and lubricate your Planer, it will give you many years of good service.

Unplug the machine before attempting any repairs.

If the Planer runs rough or has excessive vibration:

1.Check the Knife Blades to be sure they are not chipped, are securely installed, and are adjusted properly.

2.Check all chains and belts to be sure they are properly routed on their pulleys and sprockets, and are not loose.

3.Check to be sure the Table is not damaged, and operates smoothly.

4.Be sure the Crank is removed from the Planer before operation.

If the Planer will not operate at all:

1.Check to be sure the planer is plugged in, the main circuit breaker in the power source is operational, and the integral circuit breaker on the machine is operational. If either circuit breaker is open, investigate further to determine and repair the cause of the fault.

2.Check to see if the Planer is jammed.

3.Inspect the carbon brushes in the motor to determine if they are in good condition.

4.Look for broken, damaged, or loose electrical connections. Repair any faults before continuing.

If the Motor runs rough or slowly:

1.Check for debris in the cutting assembly or in the chains or belts.

2.Inspect the carbon brushes, replace if necessary.

3.Check the power source to be sure you are receiving the correct Voltage and Amperage.

If the Planer cuts unevenly, poorly, or produces a rough or chipped finish:

1.Inspect the Knife Blades to be sure they are properly installed and adjusted.

2.Remove the Knife Blades and have them sharpened by a professional sharpening service.

3.Review the suggestions for selecting a workpiece, and adjusting the depth of cut.

4.Be sure you are cutting with the grain of the wood.
