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.
Changing the Carbon Brushes.
1. Check the motor carbon brushes after each 10-15 hours
of operation.
2. These can be accessed by turning the machine on its side.
The motor is located on the underside of the machine.
The brush holders are on each side of the motor. The
brush holders can be removed by turning a coin in the slot.
3. Each brush has a max wear line marked on its side. When
the brush has worn to the line, or if it is cracked or
chipped, replace it. Be sure to replace carbon brushes in pairs.
