Hydraulic Pump 

 

 

52 

GTH-1056

 

Part No. 1278145 

 

 

 

4 

Loosen the set screw for the standby pressure 
adjustment screw. 

 

1  standby pressure adjustment screw 
2  set screw 
3  hydraulic supply line (from tank) 

 

5 

Adjust the function pump standby pressure. 
Turn the adjustment screw clockwise to 
increase the pressure or counterclockwise to 
decrease the pressure. Tighten the set screw. 

6 

Turn the engine off and remove the pressure 
gauge. 

 

Bodily injury hazard. Spraying 
hydraulic oil can penetrate and 
burn skin. Loosen hydraulic 
connections very slowly to allow 
the oil pressure to dissipate 
gradually. Do not allow oil to 
squirt or spray. 

 

How t o Adj ust  t he Functi on Pump Press ure Compens at or  

How to Adjust the Function Pump 
Standby Pressure 

Note: Two people will be required to perform this 
procedure. 

1 

Connect a 0 to 5000 psi / 0 to 350 bar 
pressure gauge to test port 'TP' on the primary 
function manifold. Refer to 

Primary Function 

Manifold Components

. 

2 

Start the engine and allow the engine to run at 
low idle. 

3 

Fully retract the boom. 

4 

Continue to activate the boom retract function 
and observe the pressure reading on the 
pressure gauge. 

 

Result: The pressure gauge reads 
3190±50 psi / 220±3.4 bar. The pump is 
functioning correctly. Proceed to step 7. 

 

Result: The pressure gauge fails to read 
3190±50 psi / 220±3.4 bar. The pressure 
setting needs to be adjusted. Proceed to step 
5.
