If the pump must be returned to an authorized repair facility,
ensure that the fuel tank is empty and the engine oil
removed.
Ship the pump with the red, shipping hydraulic cap on the
hydraulic oil tank. This red cap was either installed or
included with the unit when it was delivered. Shipping the
pump with the orange, breathable hydraulic cap installed
will cause oil to leak from the pump.
