Support and FAQ

1. The motor starter is inoperative.
   • Check motor starter coil & wiring.
2. Motor starter auxiliary contacts are inoperative.
   • Check motor starter contacts & wiring.
3. Reverse button is inoperative.
   • Check reverse button to be sure contacts are closed.
   • Check wiring.
4. Secondary contact on start button is inoperative.
   • Check contact, wired black and orange, to be sure it is operating properly
   • Check wiring.

1. Insufficient oil in the reservoir.
   
   • Fill reservoir with oil.
2. Low relief pressure.
   • Check relief pressure.
   • Clean orifice in relief valve and reset pressure.
   • Check "O" rings on relief valve for damage or leakage.
3. Oil leakage in the cylinder.
   • Check cylinder for bypassing.
   • Replace seal kit, inspect rod and cylinder tube for scoring or nicks.
   • Replace cylinder.
4. Defective pump.
   • Replace pump.
5. Oil leakage from hose fittings.
   • Tighten hose fittings.
6. Low voltage.
   • ​​​​​​​Check voltage.
7. The pump may be driven in the wrong direction of rotation.
   • Stop immediately to prevent seizure.
   • Check the direction of drive rotation (proper rotation direction is indicated by the arrow on motor).
8. The shaft broke, or shaft key sheared.
   • Visually inspect motor and pump shaft and hub couplings for damage.
   • Replace if necessary.
9. Intake pipe from reservoir blocked, or oil viscosity too heavy to prime.
   • Drain system.
   • Add clean fluid of proper viscosity and specifications.
   • Filter as recommended.
   • Check system filter for cleanliness.
10. Intake air leaks (foam in oil or sounds like gravel in the pump).
    • Check intake connections.
    • Tighten securely.
11. Units shift slowly.
    • Flow control valve (restrictor) clogged, remove and clean orifice.
12. Valve response sluggish.
    • Contaminated oil - drain and flush system.
    • Inadequate voltage, check voltage, check coil.
    • Disassemble valve and clean​.
    • Loose hub coupling.
    • Tighten set screws on hub coupling halves.

1. The solenoid valve is inoperative.
   • Check coil in the solenoid valve.
2. Reverse button is inoperative.
   • Check reverse button contacts.

1. Partly clogged intake strainer or restricted intake pipe.
   • The pump must receive intake fluid freely or cavitation results. Drain system, clean intake pipe, and clean or replace the strainer.
2. Defective bearing.
   • Replace pump.
3. Air leak at pump intake pipe joints.
   • Tighten joints as required.

1. Seal worn or damaged.
   • Replace seals or pump.

1. Continuous running.
   • When over 140 degrees F or hot in comparison with circuit lines, the pump should be shut down immediately. Before restarting, ensure that fluid cooling capacity is adequate to remove system-generated heat.
   • Install oil cooler (air or water type).
   • Install oil temperature shut down switch.
   • Check to be sure CYCON Power Pack has not been exchanged for Pressure Shifting Power Pack.
2. Undersized hydraulic lines.
   • Replace with larger hydraulic lines.
   • High ambient temp in relation to oil temp.
   • Use lower viscosity oil.
3. Excessive system leakage.
   • ​Check system for bypassing or leaks.

1. Abrasive matter in the hydraulic oil being circulated through the pump.
   • Install adequate filter or clean.
   • Replace oil more often and clean tank.
2. Viscosity of oil too low at working conditions.
   • Replace oil with factory recommended.
3. Pressure too high.
   • Reduce pump pressures to factory specifications.
4. Air recirculation causing pump noise.
   • Tighten all fittings.

1. Valve sticking or binding.
   • Disassemble & clean as necessary.
2. The viscosity of the oil is too high.
   • Change oil to factory-recommended viscosity.
3. Air in system.
   • Check for leaks, tighten fittings.
4. Low oil.
   • Fill reservoir with oil.
5. Low voltage.
   • Check primary & secondary sides of the transformer for correct voltage.

1. Check for correct voltage (incoming power).
2. Check fuses or breakers at the disconnect.
3. Check heater elements to be sure they are tight.
4. Check the wiring from starter to motor to make sure all connections are tight.
5. Check motor leads to be sure all connections are tight surges or voltage.

NOTE: Excessive overload tripping and/or motor or coil failures may occur if voltage surges or voltage drops are frequent in your area. This circumstance can be remedied by the installation of phase protectors which drop power to the motor if surges are present.
