Fill in the form. The information we need to produce the correct manual can be found on the machine label attached to your Ergolift®/Ergobalancer®.
Exploded views with parts lists are available under tab 9 of the manual.
Cause 1: The setting of the load holding valve has been disturbed. Adjust the load holding valve, see chapter “7- Adjustment instructions” – Adjustment instructions for hydraulic valves.
Cause 2: The pressure relief valve (P3) for the lowering pressure has been disturbed. Possible contamination in the valve may have caused leakage. Adjust the pressure relief valve for the lowering pressure, see chapter “7- Adjustment instructions” – Adjustment instructions for hydraulic valves. If this does not help, clean the valve or replace it with a new one.
Cause 1: Leakage from the hose connections to the valve. Tighten the couplings and hexagonal nipples. If necessary, replace the sealing washers under the hexagonal nipples.
Cause 2: Leakage from the pressure relief valve or damping valve. Tighten the nuts and replace nuts and sealing washers if necessary.
Cause 3: Leakage from the gaskets between the pressure compensation valve and the control valve body. Oil is seeping out between these parts, preferably the lower part. Replace the three O-rings between these parts.
Cause 4: The gasket in the valve body and slide is worn out, repair required.
Cause: The column/mounting bracket is tilted in the direction of the manipulator. Level the mounting flange of the column/bracket using a spirit level. Adjust with washers under the fixing screws.
Cause 1: The coupling plates in the motor terminal box are incorrectly connected. Adjust the position of the coupling plates. See chapter 8.
Cause 2: The supply voltage is too low. Connect the motor to the correct voltage (see rating plate) or change to a motor with the correct voltage.
Cause 3: The weight of the load and the lifting tool exceeds the maximum lifting capacity of the arm and the pressure relief valve on the hydraulic unit does not open properly. Reduce the load and adjust the pressure relief valve according to the adjustment instructions.
Cause 1: The weight of the load and the lifting tool exceeds the maximum lifting capacity of the arm. Reduce the load.
Cause 2: The adjustment screw of the damping valve on the control valve is fully screwed in. Adjust the damping valve according to the adjustment instructions.
Cause 3: The pressure relief valve for the lifting pressure on the hydraulic unit has been disturbed and opens at too low a pressure. Impurities in the valve may have caused leakage. Adjust the pressure relief valve according to the instructions. If this does not help, clean the valve or replace it with a new one.
Cause 4: The hydraulic pump is broken. Replace the hydraulic pump in the hydraulic unit.
Cause 5: The return filter is clogged. Replace the filter cartridge by removing the cover of the filter (dismantle the three screws).
Cause 6: The oil level in the oil tank is too low. Fill in hydraulic oil. See chapter Technical Data for suitable oil.
Cause 1: The load holding valve setting has been disturbed. Possible contamination in the valve may have caused leakage. Adjust the load holding valve, see chapter “7- Adjustment instructions” – Adjustment instructions for hydraulic valves. If this does not help, disassemble the valve and clean the parts thoroughly. Assemble and adjust as instructed. If this does not help, replace the load holding valve with a new one.
Cause 2: The piston gasket in the lifting cylinder is leaking. Replace the piston and piston rod gaskets in the cylinder.
Cause: The thumbwheel/joystick control equipment is incorrect. Check that the steering equipment is set correctly. The centering screw may need to be adjusted.
