I will get the serial # off the mast tomorrow. Today I finished disassembling the mast and with the help of a skid loader moved it into the house.

The lift does not seem to have a speed control on it. There is only a 2-way valve which is directly operated by a lever. It has a set of contacts on it which start the pump motor when in the lift position.

What is the relief valve set point on the lift hydraulic system? I am planning to use the original motor and pump but will do away with the control block that has solenoids and pressure relief valves mounted in it. I am planning to just use solenoid valves to raise and lower the cylinder.

One question I have is why use an "up" valve at all? If the pump does not start until the valve is pushed into the "on" position, and there is a check valve so fluid cannot leak back when the pump is not running, is the "up" valve not redundant?

Thanks so much,
Mike
