Warning! Danger of Amputation!
The Mayco pump is equipped with a nitrogen
accumulator, which stores hydraulic energy.
You will be required to put your hand in the
concrete cylinders or near the suttle. You are
at extreme risk if the engine is running or if
pressure is in the hydraulic system. Prior to
working on the pump, stop the engine by turning off the ignition
switch, remove starter key, place a “Do not operate” tag over the
switch and disconnect the battery. The pressure reading on the
accumulator pressure gauge must read zero. Always relieve
the accumulator circuit to zero pressure prior to working on the
pump.
Use only original Mayco components. The
quality of the components is critical to the
operator’s safety and performance of the
machine.
