YOUR BANDIT CHIPPER IS EQUIPPED WITH ONE OF TWO
HYDRAULIC PRESSURE ADJUSTMENT PROCEDURE OPTIONS.
Before attempting any hydraulic pressure settings, make sure engine is shut off, engine key 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, gauge MUST
be installed
correctly.
1. First put control handle in off position.
2. Disconnect hydraulic hose going from autofeed plus block (or from flow divider if machine not equipped
with autofeed plus) to feedwheel control valve at the feedwheel control valve end.
. Install pressure gauge in port on feedwheel control valve where you disconnected the hose and plug the
end of the hose.
. Start engine and adjust engine to full throttle to activate reading on pressure gauge.
5. Pressure gauge should read maximum 2500 PSI (172 bar).
ONLY RUN ENGINE FOR 4-5 SECONDS TO SET PRESSURE OR YOU MAY DAMAGE HYDRAULICS.
6. Locate relief next to autofeed solenoid, loosen jam nut, use an allen wrench to readjust relief pressure
setting if needed, and then retighten jam nut.
7. Reassemble hose from autofeed plus block (or from flow divider) to feedwheel control valve.
8. Check for hydraulic leaks.
9. Relief valve pressure should be checked and/or readjusted every month for best performance.
