Belinda GrimesSep 16, 2025
If the hydraulic variable displacement pump fails on your HAKO Scrubber, it could be due to the pump leaking, requiring you to replace the seals. Clean or replace the relief valve(s) at the pump if they are stuck. Replace defective gears if there is a drive coupling malfunction or if the charge pump gears are worn or scored. Adjust the control linkage and check for binding if the control linkage is out of adjustment. Maintain the correct hydraulic fluid level in the reservoir and keep suction hose fittings tight to prevent damage due to air entering the hydraulic system.

If the hydraulic gear pump fails on your HAKO Scrubber, it could be due to pump leaking, which requires replacing the seals or RR pump. Replace the drive coupler if it has failed. If the gears are worn or scored, rebuild the pump or replace it with an RR pump. Check and fill the oil supply if it is low. Replace the strainer inside the reservoir if the oil strainer is clogged. Use the recommended viscosity oil if the oil is incorrect. Maintain the correct hydraulic fluid level in the reservoir and keep suction hose fittings tight to prevent damage due to air entering the hydraulic system.

K
Katherine LoganAug 22, 2025
If your HAKO Scrubber's engine overheats, it could be due to several reasons. The coolant level might be low, so you should supply coolant. The fan blade could be installed incorrectly and needs reinstalling as a pusher type fan. A clogged radiator should be flushed. A loose fan belt needs tightening, or the thermostat might be defective and requires replacement.
