6.5 Zero Leak Case Drain Relief Valve
The mulcher is equipped with a case drain line that is
to be routed to the skidsteer hydraulic reservoir.
It is normal for a hydraulic motor to have a slight
amount of internal leakage.
The case drain line will allow this internal leakage to
be returned to the reservoir, preventing excessive
pressure on the motor seal.
If the case drain line is not connected or becomes
obstructed, the zero leak relief valve will vent the
pressurized hydraulic fluid to the atmosphere. The zero
leak relief valve will self reset after hydraulic pressure
reduced.

WARNING
Pressurized fluids can penetrate the skin.
Keep bystanders away from machine
during operation.
A tiny, almost invisible leak can penetrate
the skin, thereby requiring immediate
medical attention.
If hydraulic fluid is coming out of the zero leak relief
valve, shut down machine immediately. Inspect the
case drain line connection and lines. Contact your
dealer if case drain lines and connections are good.
NOTICE
Environmental hazard.
Clean up any spilled hydraulic fluid
immediately.
A properly installed case drain protected by a zero leak
relief valve will save the work of replacing the motor
shaft seal and also improve the efficiency of your
hydraulic system.
