Assembly

Drawbar hydraulic circuit

NOTE

In order to protect the cylinder ports, they are delivered facing down. It is not

necessary to disassemble the cylinder to turn it up, it is just necessary to give

a turn on the cylinder barrel.
Always use thread sealing tape to couple the male quick couplers to the hoses.

NOTE The drawbar cylinder rod must be facing the drawbar side.
