3. Remove the panels on both sides of the planer, and apply a light grease to the chains. Note: Do not apply grease to the belts. 4. Apply a light coat of grease to the chain on the underside of the machine. The motor and electrical controls should be maintained. 1. Keep the motor and electrical controls dry and clean. Do not expose the electrical portions of the machine to water or wet conditions. 2. Keep the motor free of chips, sawdust, grease, and debris. 3. The motor bearings are sealed and do not require additional lubrication. ADJUSTING THE CUTTING KNIVES WARNING: Be sure the machine is turned OFF and UNPLUGGED before attempting any adjustments. The Cutter Head assembly can be accessed by removing the cover from the top of the machine. 1. Remove the top cover (#326) from the top of the machine by removing the bolts which hold it in place. 2. Please refer to Figure 11. when checking knife adjustment. Position the knife Gauge (E) on the cutter head and knife blade as shown. The gauge must contact the knife blade and the cutter head at all three points shown. The blade is adjusted too low if there is a visible space between the blade edge and the gauge. The knife blade is too high when the gauge rocks from side to side on the cutter head when contacting the knife blade. 3. To adjust the blade setting, loosen the locking nuts (A) just enough to allow the blade (C) to move against the Lock Bar (B). To raise the knife blade, turn adjustment screw (D) counterclockwise. To lower the knife blade, turn the adjustment screw clockwise and press down on the blade. NOTE: The blade must be adjusted at both ends. It is important that you adjust the blade along its entire length, so the blade has an even depth along its entire length. 4. When the knife blade is properly adjusted, tighten the locking nuts (A) firmly to lock it in place. Be sure these nuts are on tight. Re-check to be sure the knife blade did not slip during tightening. Figure 10. Checking the Knife Blade Figure 11. Knife Blade Gauge Page 9 SKU # 41831 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. Figure 12.
