PRESSURE SETTINGS:
The hydraulic system is divided into two pressure circuits, each having its own protective ad-
justable relief valve in the inlet sections of the control valve. The functions operated by the
control valve sections require different pressures for different functions. These are shown be-
low:
1. Hoist Circuit -- 2500 PSI (172 bar) at full flow.
2. Boom and Outrigger Circuit -- 3000 PSI (207 bar) at full flow, on IC-200-3, 2600 PSI (179
bar) on IC-200-2.
3. Boom swing work ports -- 1500 PSI (103 bar) at full flow.
A good quality pressure gauge with at least a 3000 PSI (207 bar) scale is required to make
adjustments properly. A 3000 PSI (207 bar) working pressure hose with adapters to fit the 3/8
tube pressure ports is required to install the gauge where it can be read easily.
The following procedures are suggested when taking pressure readings:
HOIST CIRCUIT:
Remove the 3/8" JIC cap from the fitting on the front of the control valve near the hoist control
section and inst all a 3000 PSI (207 bar) pressure gauge. To obtain full flow reading, run
pump full speed, pull hoist control to the RAISE position and hold unt il maximum reading is
made. The anti-two-block override switch must be actuated. If a pressure of 2500 PSI (172
bar) is not possible, check the following:
1. Broken mechanical connection to the pump shaft.
2. Low oil level in the reservoir.
3. Clogged suction filter or shutoff valve not fully opened.
4. Valve spool linkage not allowing control valve to fully open. Valve spool should move 3/8"
(9.5 mm) each way from neutral position.
5. Anti-two-block system malfunction.
6. Adjust relief valve by loosening nut on top of relief cartridge above winch gauge port and
turning socket-head screw clockwise to increase pressure or counter-clockwise to lower
pressure.
7. Foreign particle in pilot operated relief.
8. Worn or defective hydraulic pump.
