Start troubleshooting by verifying the baler's basic functionality. Ensure the machine is properly powered and all safety interlocks are engaged, as loose connections or tripped switches often cause unexpected shutdowns. Observe the control panel for error indicators or warning lights, which can provide initial clues about the nature of the malfunction.

Examine moving parts for signs of obstruction or damage. Check the baling chamber for foreign objects that may prevent the ram from moving smoothly. Inspect for signs of excessive wear on rollers, guides, or compression plates, as worn parts often lead to uneven operation.

For hydraulic balers, check fluid levels and look for leaks around hoses, fittings, or cylinders. Low fluid levels or contaminated fluid can cause weak compression. For pneumatic systems, verify air pressure and check for leaks in hoses or valves.

Operate each component individually to identify which part is malfunctioning. Check sensors that detect chamber fullness or door position, as misaligned or dirty sensors often send incorrect signals. If the baler fails to reach proper compression, verify that pressure settings are correctly calibrated.
