Cause

• Poor chain lubrication.

Correction

• Check the flow adjustment on the valve.
• Make sure the oil tube is not pinched or cut.
• Ensure the oil port on the cutting bar adjustment block aligns correctly with the lubrication hole on the cutting bar.

Cause

• Internal leak in the saw motor.

Correction

• Motor must be replaced.

Cause

• Insufficient pressure at the main hydraulic block.

Correction

• Increase the pressure by tightening the relief valve to reach 600 psi on the gauge when the saw is activated.

Cause

• Splitter return is activated during cutting bar descent.

Note / Correction

• On some processors, we observed that a wire bundle installed too tightly could pull the lever to the right when it is pulled down, causing the splitter return to engage unintentionally and resulting in hydraulic pressure loss. Correct the routing/tension of the wiring.

Cause

• Lack of hydraulic oil.

Correction

• Check that the hydraulic oil volume in the processor is sufficient.
