HYDRAULIC SECTION
HYDRAULIC PRESSURE ADJUSTMENT PROCEDURE
FOR YOUR BANDIT CHIPPER.
The relief valve is typically located internally in the control valve. Do not adjust this relief valve above
1500 PSI. The relief valve system is a simple spring tension design but small pieces of debris can stick the
valve partially open which weakens the feedwheel power. The relief as well as hydraulic oil, and screen
must be kept clean.
1.
POPPIT VALVE:
This ball opens and closes to relieve excess
pressure on hydraulic system.
2.
RELIEF SPRING:
This spring tensions the amount of pressure
required to open the relief valve ball. This
spring weakens and must be readjusted every
3 months,
3.
SLOTTED SET SCREW:
Turn clockwise to increase pressure, but do not
surpass maximum of 1500 PSI.
4.
HEX HEAD PLUG:
Remove to access the relief valve.
CHECKING AND ADJUSTING OF RELIEF VALVE PRESSURE
1.
First put control handle in neutral position.
2.
Disconnect one hose going from hydraulic motor
to control valve and plug that hose.
3.
Leave all other hydraulic hoses connected.
4.
Install pressure gauge in port left open from
the disconnected hose on the control valve.
5.
Start engine, and engage control handle to
normal operating position.
6.
Adjust engine to full throttle to activate reading
on pressure gauge.
7.
Pressure gauge should read maximum 1500 PSI.
ONLY RUN ENGINE FOR 4-5 SECONDS TO
SET PRESSURE OR YOU MAY DAMAGE
HYDRAULICS.
8.
Readjust relief pressure setting if needed, if not
needed, shut off engine remove plug and gauge.
Reassemble hydraulic hose to control valve.
9.
Check for hydraulic leaks.
10. Relief valve pressure should be checked and/or
readjusted every 3 months for best performance.
MAINTAIN FEEDWHEEL HYDRAULIC PRESSURE AT 1500 P.S.I.
WARNING
Before attempting any hydraulic pressure settings, make sure engine is shut off, engine key removed and in
your pocket. To correctly check relief valve pressure, gauge MUST be installed correctly.
