Use of a hydraulic power supply with fluid tempera-
tures above 154°F (68°C) can create hot surfaces
which can burn if touched.
• Do not touch pump, motor, or if hydraulic system
fluid is above 154°F (68°C).
• Allow sufficient time for pump and motor to cool
before attempting any service or repair.
Replace throat seals if fluid leaks excessively
through the weep tube (B), page 4. This procedure
can be done without disassembling entire
reciprocator.
