Hydraulic System Troubleshooting, Testing and
Adjustment

POWER MODE VALVE

CURRENT SIGNAL AND HYDRAULIC PRESSURE ADJUSTMENTS

The electromagnetic pressure proportioning control (EPPR) "power mode" valve is located on the
underside of the pumps (not visible in the harness connections drawing, because it is underneath the
assembly), near the engine/pump flexible coupling, adjacent to the pump return line. To test and adjust
power shift current and pressure through the power mode valve a multi-lead jumper harness is required.
The jumper harness (which is available through Daewoo After Sales Service, or could be spliced together
from commonly available, purchased parts) has extra leads so that a VOM meter can be connected to the
circuit.

To set up the testing equipment, turn off the engine and disconnect the single electrical lead from the
power mode valve. Attach the jumper harness to the terminal on the valve, connect the test leads of the
multimeter to the extra leads on the harness and reconnect the valve electrical lead.

Vent the lever on top of the hydraulic tank to relieve pressure and connect an in-line "t-style" adapter to the
valve pressure port. Install a 60 bar (1,000 psi) test gauge in the adapter.

Restart the engine and increase engine RPM by turning the speed control to the maximum speed setting.
Warm up the engine and hydraulic system until hydraulic oil temperature is at least 45°C (113°F). Select
Power Mode on the Instrument Panel. Check current readings (in milliamps) on the VOM meter and
hydraulic pressure gauge readings and make sure both conform to the values in the table below.

NOTE:

If recorded values do not conform to the specified current or pressure in the table, back off
the lock nut on the end of the valve, turn the adjusting screw 1/4 turn and re-check current
and pressure. Repeat adjustment as required to obtain specified performance and
retighten the valve lock nut.

WARNING!

This procedure should be done with two people. To reduce the chance of accident or unintended
start-up, one person should remain at the operator’s control stand while checks and
adjustments are made.
