following tests: Charge Pressure Test, Wheel Motor Efficiency Test, and/or
Traction Pump (P1) Flow and Relief Valve Test.
If a steering or lift circuit problem exists, consider performing one or more of the
following tests: Steering Relief Valve Pressure Test (model 08745 only), Steering
Cylinder Test (model 08745 only), Lift Relief Valve Pressure Test (model 08743
only), Lift Cylinder Test, and/or Implement/Charge Pump (P2) Flow Test.
If an optional attachment circuit problem exists, consider performing one or more
of the following tests: Relief Valve Pressure Test, Attachment Motor Efficiency
and/or Attachment Pump (P3) Flow Test.
