5�4 Motor Shaft Seal
The cutter is equipped with a case drain line that
is to be routed to the skid steer 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 oil 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 oil 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 connection are good.
NOTICE
Environmental hazard�
Clean up any spilled hydraulic oil
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.
