3. The motor is running the the ram is not moving normally
4. My compactor will not move in reverse
5. My pump is making a gravel sounding noise
6. My pump shaft seal is leaking
7. My compactor is producing excessive heat
8. My compactor is experiencing excessive wear & tear
9. My compactor is experiencing erratic operation
10. My compactor's overload trips frequently

*Problem*	*Cause*	*Solution*
1. UNIT WILL NOT START Top	1) No electrical power to unit	1A. Turn on main disconnect
	1) No electrical power to unit	1B. Replace fuses or reset breakers
	2) No electrical power to control circuit	2A. Check primary and secondary sides of transformer
		2B. Check for correct voltage. Check control fuses.
		2C. Check stop button
		2D. Check start button to be sure contact closes when depressed
	3) No electrical power to motor	3A. Check heater resets
2. UNIT WILL NOT CONTINUE RUNNING WHEN START BUTTON IS RELEASED Top	1) Motor starter is in-operative	1A. Check motor starter coil & wiring
	2) Motor starter auxiliary are inoperative	2A. Check motor starter and wiring
	3) Secondary contact on start button is inoperative	3A. Check contact, wired black and orange, to be sure it is operating properly
	3) Secondary contact on start button is inoperative	3B. Check wiring
3. MOTOR RUNS BUT RAM DOES NOT MOVE NORMALLY Top	1) Insufficient oil in reservoir	1A. Fill reservoir with oil
	2) Low relief pressure	2A. Check relief pressure (refer to PROCEDURES-HYDRAULIC PRESSURE CHECK and PRESSURE SETTINGS for correct pressure.
		2B. Clean orifice in relief valve and reset pressure.
		2C. Check 'O" rings on relief valve for damage or leakage.
	3) Oil leakage in cylinder	3A. Check cylinder for bypassing
		3B. Replace seal kit, inspect rod and cylinder tube for scoring or nicks.
		3C. Replace cylinder
	4) Defective pump	4A. Replace pump
	5) Oil leakage from hose fittings	5A. Tighten hose fittings
	6) Low voltage	6A. Check voltage
	7) Pump may be driven in the wrong direction of rotation	7A. Stop immediately to prevent seizure. Check direction of drive rotation (proper rotation direction is indicated by arrow on motor)
	8) Shaft broken, or shaft key sheared	8A. 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	9A. 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 pump)	10A. Check intake connections. Tighten securely.
	11) Units shift slowly	11A. Flow control valve (restrictor) clogged, remove and clean orifice.
	12) Valve response sluggish	12A. Contaminated oil-drain and flush system.
		12B. Inadequate voltage, check voltage, check coil.
		12C. Disassemble valve and clean
	13) Loose hub coupling	13A. Tighten set screws on hub coupling halves.
4. UNIT WILL NOT REVERSE	1) Solenoid valve is in-operative	1A. Check coil in solenoid valve
5. PUMP MAKES GRAVEL SOUNDING NOISE Top	1) Partly clogged intake strainer or restricted intake pipe	1A. Pump must receive intake fluid freely or cavitations result. Drain system, clean intake pipe and clean or replace strainer.
	2) Defective bearing	2A. Replace pump
	3) Air leak at pump intake pipe joints	3A. Tighten joints as required.
6. PUMP SHAFT SEAL LEAKING	1) Seal worn or damaged	1A. Replace seals or pump.
7. EXCESSIVE HEAT Top	1) Continuous running	1A. When over 140 degrees F or hot in comparison with circuit lines, pump should be shut down immediately. Before restarting, insure that fluid cooling capacity is adequate to remove system generated heat.
		1B. Install oil cooler (air or water type)
		1C. Install oil temperature shut down switch
	2) Undersized hydraulic lines	2A. Replace with larger hydraulic lines
	3) High ambient temperature in relation to oil temperature.	3A. Use lower viscosity oil
	4) Excessive system leakage	4A. Check system for bypassing or leaks.
8. RAPID WEAR & TEAR Top	1) Abrasive matter in the hydraulic oil being circulated through pump	1A. Install adequate filter or clean.
		1B. Replace oil more often and clean tank
	2) Viscosity of oil too low at working conditions	2A. Replace oil with factory recommended .
	3) Pressure too high	3A. Reduce pump pressures to factory specifications.
	4) Air recirculation causing pump noise	4A. Tighten all fittings.
9. ERRATIC OPERATION Top	1) Valve sticking or binding	1A. Disassemble & clean as necessary
	2) Viscosity of oil too high	2A. Change oil to factory recommended viscosity.
	3) Air in system	3A. Check for leaks, tighten fittings
	4) Low oil	4A. Fill reservoir with oil
	5) Low voltage	5A. Check primary & secondary sides of transformer for correct voltage.
10. OVERLOAD TRIPS FREQUENTLY Top		1A. Check for correct voltage (incoming power).
		1B. Check fuses or breakers at disconnect
		1C. Check heater elements to be sure they are tight.
		1D. Check wiring from starter to motor to make sure all connections are tight
		1E. 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.
