Note: When measuring lift circuit relief pressure,
counterbalance pressure, and “Traction Plus” counter-
balance pressure on machines with serial numbers
above 250000000, pressures will be approximately 125
psi (8.6 bar) higher than the specifications listed above.
Refer to the Testing section in this chapter for detailed
information.
