CORRECTION
Check control valve linkage
and repair if worn/defective.
Refer to “Aeration of
Hydraulic Fluid”.
Check coupler(s). Repair
or replace.
Check orifice plate instaiiation.
Hydraulic Hose or Tubeline
Restriction (Hoses/Tubeiine
kinked or pinched).
Lift Cylinder Piston
Assembly Leakage.
Relief Valve Erratic or
Set Below Specifications.
Control Valve Leaking
Internally. (Bypassing fluid
within valve.)
Inadequate Hydraulic Pump
Capacity
Check hoses and tubelines
for evidence of restriction.
Check cylinders for leakage
as described in Service
Section under Cylinder
Leakage Tests.
Check Relief Valve Setting
as described under Relief
Valve Test.
Replace Control Valve and
recheck operation.
Refer to “Hydraulic Pump
Capacity Inadequate”.
