Question 1

Problem: Unit Will Not Start

Accepted Answer

No electrical power to the unit
Turn on Main Disconnect
Replace fuses or reset breakers

No electrical power to control circuit
Check primary and secondary sides of the transformer
Check for correct voltage.
Check control fusesCheck stop button
Check start button to be sure contact closes when depressed

No electrical power to the motor
Check heater resets

Question 2

Problem: Unit Will Not Continue Running When Start Button Is Released

Accepted Answer

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

Question 3

Problem: Motor Runs, But Ram Does Not Move Normally"

Accepted Answer

Insufficient oil in the reservoir
Fill reservoir with oil
 Low relief pressure
Check relief pressure
Clean orifice in relief valve and reset pressure
Check "O" rings on relief valve for damage or leakage
 Oil leakage in the cylinder
Check cylinder for bypassing
Replace seal kit, inspect rod and cylinder tube for scoring or nicks
Replace cylinder
 Defective pump
Replace pump
 Oil leakage from hose fittings
Tighten hose fittings
 Low voltage
​​​​​​​Check voltage
 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)
 The shaft broke, or shaft key sheared
Visually inspect motor and pump shaft and hub couplings for damage. Replace if necessary
 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. 
 Intake air leaks (foam in oil or sounds like gravel in the pump)
Check intake connections. Tighten securely
 Units shift slowly
Flow control valve (restrictor) clogged, remove and clean orifice
 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

Question 4

Problem: Unit Will Not Reverse

Accepted Answer

The solenoid valve is inoperative
Check coil in the solenoid valve
 Reverse button is inoperative
Check reverse button contacts

Question 5

Problem: Pump Makes Noise - Sounds Like Gravel

Accepted Answer

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
 Defective bearing
Replace pump
 Air leak at pump intake pipe joints
Tighten joints as required

Question 6

Problem: Pump Shaft Seal Leaking

Accepted Answer

Seal worn or damaged
Replace seals or pump

Question 7

Problem: Excessive Heat

Accepted Answer

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
 Undersized hydraulic lines
- Replace with larger hydraulic lines
- High ambient temp in relation to oil temp
- Use lower viscosity oil
 Excessive system leakage
​​​​​​​- Check system for bypassing or leaks

Question 8

Problem: Rapid Wear

Accepted Answer

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

Question 9

Problem: Erratic Operation

Accepted Answer

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

Question 10

Problem: Overloads Trip Frequently

Accepted Answer

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