Before attempting any hydraulic pressure settings, make sure engine is shut off, the ignition key is
removed and in your possession, hydraulic oil is clean, hydraulic tank is 7/8 full, and the machine has
been pre-run to warm the hydraulic oil. To correctly check relief valve pressure, the pressure gauge
MUST
be installed correctly.
1. First put control handle in off position.
2. Disconnect hose coming out of the port farthest from the handle of the control valve from the optional
motor or cylinder, and plug the hose.
. Leave all other hydraulic hoses connected.
. Install pressure gauge in the valve port which had the hose of the optional motor or cylinder disconnected.
. Start engine and adjust engine to full throttle to activate reading on pressure gauge.
6. Only operate the valve for that component to activate pressure gauge. Pressure gauge should read the
maximum specified PSI (bar) for that component, see page 56.
ONLY RUN ENGINE FOR 4-5 SECONDS TO SET PRESSURE OR YOU MAY DAMAGE HYDRAULICS.
7. Readjust relief pressure setting if needed, if not needed, shut off engine and remove plug and pressure
gauge. Reassemble control valve to optional motor or cylinder.
8. Check for hydraulic leaks.
9. Relief valve pressure should be checked and/or readjusted every month for best performance.
