NOTE: Letters on the hose set diagram show the hydaulic hose routing between the
backhoe control valve and the various hydraulic cylinders. Simply match the letter
on the control valve port to the same letter on the hydraulic hose ends. Example:
Hose Assembly labeled "C" runs from the upper Left Stabilizer port on the hydraulic
control valve - through the mainframe and to the barrel end fitting on the left stabilizer
cylinder.

NOTE: The fittings on the hydraulic cylinders have been altered for clarity purposes.
This will assist you in distinguishing between the rod end and the barrel end of the
various hydraulic cylinders.
