Maintenance

Leakage Inspection

After commissioning visually inspect system for leaks. Perform visual leak inspection at regular intervals. It is good practice to visually 
inspect for leaks prior to every use.

Cleanliness Inspection

Maintain a dirt-free system. This is very important in applications in environment with a high degree of airborne contaminants.  
Leak detection is easier and quicker on clean system.

Oil Level Inspection

Check oil level every 2 to 4 hours during the first day of use. Check oil level twice a day during first week and once a week thereafter.

CAUTION! If necessary, top off oil reservoir using proper fluid type. Do not mix oil types.  

Refer to Oil Equivalent Table, pg. 15. 

Additional Maintenance Points

•  Always power down HPU prior to performing maintenance.

 

•  Place a label or tag on HPU indicating type of fluid that is installed.

 

•  Replace any hoses that appear to be worn or chafed.

Troubleshooting

Problem

 Possible Cause

How to Verify

None of the functions are working

No electrical power

Check power to ECB
Check motor switches on ECB
Check wiring from ECB to motor
Check main circuit breaker to ECB
Check lights on micro circuit breaker. If red, reset circuit breaker.

Motor is not operating

Check thermal switch trip light on ECB
Verify proper voltage at motor
Verify operation of motor relay

Motor is stalling

Pressure relief valve not working
Not enough current going to motor

Pump is not operating correctly

Check oil level in reservoir
Repair pump

Single function is not working

Function is turned off

Check function breaker in ECB

Switch is not working

Check wiring from deck switch to ECB

Valve is not working

Check wiring from ECB to directional valve
Check lights on micro circuit breakers. If red, reset circuit breaker.
Check operation of directional valve solenoids
Perform manual override with hex wrench

Functions are running slow

System leak present

Check hose and fitting connections

Reduced motor speed

Verify adequate battery voltage to motor

Relief valve is opening

Hydraulic line is plugged

Pump flow is reduced

Check oil level in reservoir

Filters are plugged

Check filter status gauge. Replace filter element if needed.

Function load reduced

System leak present

Check hose and fitting connections

Insufficient motor torque

Verify batteries are fully charged

Relief valve is opening

Check relief valve opening pressure

Pump is not operating correctly

Check oil level in reservoir
Check system pressure under load

CAUTION! If leak is present, decrease system pressure to 0 psi before tightening fittings.
