Cause: Worn flywheel brake or oily friction surfaces. Fix: Clean the brake drum and adjust the brake tension.
Cause: Pump motor failure or empty oil tank. Fix: Check pump power and refill the reservoir.
Cause: Lack of vacuum or improper punch entry depth. Fix: Use a slug-retention die or adjust the punch stroke.
Cause: Crankshaft misalignment. Fix: Check the main bearing alignment and realign the shaft.
Cause: Faulty synchronization relay. Fix: Replace the safety relay; buttons must be pressed within 0.5s of each other.
Cause: Broken wire in the pedal cable or faulty internal switch. Fix: Inspect the cable for pinches and test the switch for continuity.
Cause: Dead internal battery in the PLC. Fix: Replace the PLC lithium battery (typically needed every 3–5 years).
Cause: Blown thermal overload in the control panel. Fix: Reset the thermal relay and check for mechanical binding in the screw.
Cause: Misaligned feeder or uneven pressure on the rollers. Fix: Re-center the feeder and adjust the roller tension.
Cause: Feeder timing is slow or the stroke is too fast. Fix: Sync the feeder speed with the press SPM.
Cause: Excessive moisture in the factory air lines. Fix: Install an industrial air dryer at the compressor outlet.
Cause: Failing high-speed motor bearing. Fix: Replace the motor bearings before they seize and damage the shaft.
Cause: Using the wrong bolster plate or incorrect ram adjustment. Fix: Verify the shut height specs and adjust the ram height.
Cause: Misaligned transmitter/receiver or dirty lenses. Fix: Clean the glass lenses and realign the brackets until the green light shows.
Cause: Improper chute angle or oversized scrap. Fix: Increase the chute angle or use a scrap-chopper.
Cause: Thermal expansion of the frame or bushes. Fix: Ensure the cooling/lubrication system is functioning and check the room temperature.
