What to do if grease is discharged at the pressure relief valve in Manitowoc MLC300?
- A
  Austin KennedyJul 26, 2025
  If grease is being discharged at the pressure relief valve of your Manitowoc Construction Equipment, it indicates a blockage in the meter valves, hose, tubing, or at the bearing. You can test the system with a grease gun at the system's manual grease fitting. Loosen each outlet line at the primary valve, one at a time. The blocked outlet line will start flowing grease and the indicator pin will start indexing. Retighten all outlets at the primary valve. Trace the hose that flowed to its secondary valve and repeat the process of loosening each outlet one at a time until the blocked line is found. Retighten all outlets. Repair any bearing blockage. If a metering valve is causing the blockage, replace the valve.

What to do if the pump motor runs but no grease is discharged in Manitowoc MLC300 Construction Equipment?

  If the pump motor is running in your Manitowoc Construction Equipment but no grease is being discharged, it could be due to an air pocket at the pump element inlet or a blocked pump inlet. First, disconnect the main delivery hose from the pump outlet and run the pump until solid grease with no bubbles flows from the outlet. If solid grease does not discharge after 20 minutes, the pump inlet is likely blocked. To resolve a blocked pump inlet, remove the pump element from the pump body and check the suction inlet port for foreign particles. Reassemble the pump and element, then test the pump. If the pump element still does not discharge grease, replace the element.

Why will the pump not operate in my Manitowoc MLC300?
- D
  Debra BlackAug 6, 2025
  If the pump in your Manitowoc Construction Equipment will not operate, there are two potential causes. It might not be receiving the necessary 24-volt DC input, or the pump cam could be blocked. First, check the fuses and electrical supply to ensure the pump is getting power. If the electrical supply is confirmed, trace the electrical supply to the pump to identify any issues and repair them. If voltage is available to the pump, check for any blockage. If no blockage is found, consider replacing the pump motor.

What to do if the Manitowoc Construction Equipment pump operated with an empty reservoir?
- C
  Cheryl HillAug 12, 2025
  If the pump in your Manitowoc Construction Equipment operated with an empty reservoir, it's likely because the grease level in the reservoir is low. To resolve this, fill the reservoir and test the system with a grease gun at the system's manual grease fitting. Then, disconnect the main delivery hose from the pump and observe until solid grease with no bubbles flows from the outlet. Finally, reconnect the main delivery hose to the pump outlet.

  If a lubrication point on your Manitowoc Construction Equipment is not receiving grease, it's likely due to a cut in the hose or tubing. The solution is to replace the damaged hose or tubing.
