The anti-kickback fingers hang from a rod suspended across the cutter headstock. The anti-kickback fingers should be inspected regularly. Check the fingers (Figure 37) to ensure that they swing freely and easily. If the fingers do not swing freely and easily, clean them with a wood resin solvent. Proper operation of the anti-kickback fingers is essen- tial for the safe operation of this machine. Failure to ensure that they are working properly could result in serious operator injury. Figure 37. Anti-kickback fingers. Do not apply oil or other lubricants to the anti-kickback fingers. Oil or grease will attract dust, restricting the free movement of the fingers. -36 W1754 20" Planer With Mobile Base Pulley Alignment Proper pulley alignment (see Figure 38) prevents premature belt wear. The pulleys are properly aligned when they are parallel and in the same plane as each other. Use a straightedge on the edge of the pulleys to judge alignment. Should you find that the pulleys are out of alignment, do these steps: 1. DISCONNECT THE PLANER FROM THE POWER SOURCE! 2. Remove the motor and front access panels, the V- belt cover, and loosen the belt tension (Page 24). 3. Using a 14mm wrench, loosen the motor mount fasteners shown in Figure 39 just enough to allow the motor to be repositioned. 4. Slide the motor as required to align the pulleys. 5. Re-tighten the motor mount fasteners. 6. Inspect V-belts for damage caused by bad pulley alignment and replace belts as a matched set of three if necessary. 7. Re-tension the V-belts. 8. Replace the V-belt cover, motor and front access panels. OFF Figure 38. Example of checking belt alignment. Figure 39.

W1754 Wiring Diagram W1754 20" Planer With Mobile Base SERVICE Troubleshooting This section covers the most common problems and corrections with this type of machine. WARNING! DO NOT make any adjustments until power is disconnected and moving parts have come to a complete stop! PROBLEM Motor will not start. POSSIBLE CAUSE 1. Emergency stop button depressed. 2. Thermal protection circuit. Breaker amperage is set too low, or motor is at fault. 3. Open circuit in motor or loose connections. 4. Start capacitor at fault. CORRECTIVE ACTION 1. Rotate clockwise until it pops out/replace. 2. Unplug machine, open magnetic switch cover, turn amperage dial on Thermal Protection Circuit Breaker to a higher amperage setting. If switch is maxed out, replace motor. 3. Inspect all lead connections on motor for loose or open connections. 4. Replace start capacitor. Fuses or circuit breakers blow. 1. Short circuit in line cord or plug. 1. Repair or replace cord or plug for damaged insulation and shorted wires. Motor fails to develop full power (output of motor decreases rapidly with decrease in voltage at motor terminals). 1. Undersized wires or circuits too long. 2. Motor run capacitor at fault. 1. Increase wire sizes or reduce length of the circuit. 2. Replace run capacitor. Motor overheats. 1. Motor overloaded during operation. 2. Air circulation through the motor restricted. 1. Reduce cutting load; take lighter cuts. 2. Clean out motor to provide normal air circulation. Motor stalls or shuts off during a cut. 1. Motor overloaded during operation. 2. Thermal protection circuit breaker amperage is set too low or motor is at fault. 3. Short circuit in motor or loose connections. 4. Circuit breaker tripped. 1. Reduce cutting load; take lighter cuts. 2. Unplug machine, open magnetic switch cover, turn amperage dial on Thermal Protection Circuit Breaker to a higher amperage setting. If switch is maxed out, replace motor. 3. Repair or replace connections on...
