OPERATION AND TROUBLESHOOTING GUIDE 

 

SYMPTOMS AND SOLUTIONS - EASY TROUBLESHOOTING GUIDE 

 

Please use this guide to easily troubleshoot your Eagle Hydraulic power unit. It is recommended to go through each step, 
as this guide has been created in a logical sequence. If followed from top to bottom, you should go through all possible 
symptoms and should be able to find the problem.  
 
The most common situation you can easily fix: 
 

Problem: If you have an option 2 and you are not able to build pressure 
 

Cause: The manual override of the 2-way poppet valve has probably been left open  
 
How to fix it:  Push down on the poppet valve and turn clockwise until it locks.  The manual override is now closed, and it 
should operate properly.  

 

 
The following table lists the most common problem you can encounter and what you should verify in each case.  
 

SYMPTOM OR PROBLEM 

VERIFICATION TO DO 

The motor is not running 

 

Check the connection from your power supply to the DC motor. 

 

Check the power to the solenoid starter. 

Solenoid starter clicks but the motor does not start 

 

Check for loose wire from solenoid starter to DC motor. 

 

Make sure you have the right gauge of wire from your battery 

to the unit. 

 

Check for cracked terminal on solenoid starter, if so, replace 

start solenoid. 

 

If it’s an older unit, check for rust buildup inside DC motor. 

 

Motor runs, but unit will not build hydraulic pressure 

 

Solenoid valve manual override is open

 

Some of our units (Option 2) are equipped with a two-position 

valve with a mechanical manual override.  With stem of valve 

pointing up, push down and turn clockwise until stem won’t 

turn.  The manual override is now closed.  Retry unit. 

 

Gear pump might not be priming

.  Loosen the  relief valve, 

replace relief valve (torque to 22Nm) and retry unit.
