6.4 How to Move the Mower if the Engine Won’t Start
Rotate both of the hydro bypass valves on the side of each
hydraulic pump about ½ turn counterclockwise. It is important
not to over tighten these. Damage may occur to the pump if
this valve is over tightened.
6.5 Hydraulic System
Whenever servicing the hydraulic system, it is of the utmost importance to keep any dirt or debris from
getting into the system. Clean off all parts before disassembly and
assembly. When any of the hydraulic parts are disconnected or
removed or when the oil is changed, air must be bled from the system.
If air is entrained in the system, loss of power, excessive heat, and
damage to the hydraulic pumps may occur.
