TEST NO. 2: Remote Hydraulics Relief Pressure

1. Make sure hydraulic oil is at normal operating temper-
ature before performing tests.
2. Raise and support dump box, if equipped, then en­
gage parking brake and stop the engine.
3. Install tester in series between pump outlet (pressure
hose) and dump valve. Make sure tester flow control
valve is open.
The engine must be running to perform hy­
