Why won't wood split, or splits extremely slowly on my Central Machinery 67090 Log Splitter?

  Jillian Williams DDSAug 4, 2025
  If wood won't split or splits extremely slowly on your Central Machinery Log Splitter, consider these potential causes: * There might be air in the oil. Check for excessive air in the hydraulic reservoir. * There could be excessive control valve inlet vacuum. Inspect the control valve inlet hose for blockages or kinks. * The control valve setting may be low. Have a qualified service technician adjust the control valve with a pressure gauge. * There may be an internal control valve leak. If so, have a qualified service technician repair or replace the control valve. * The cylinder might be internally damaged. In this case, have a qualified service technician repair or replace the cylinder.

What to do if the ram will not move on my Central Machinery 67090?

  Holly JacksonAug 18, 2025
  If the ram on your Central Machinery Log Splitter isn't moving, there are several potential causes: * The handwheel may be open. Try turning the handwheel clockwise until it is snug. * There might be wood or foreign objects wedged under the ram. Remove any obstructions. * The hydraulic lines or control valve could be blocked. In this case, flush and clean the splitter’s hydraulic system. * The control valve or cylinder piston might be damaged. If so, have a qualified service technician repair or replace the affected component.
