Cutting Units Raise, But Will Not Stay Up
NOTE: Lift cylinders and check valves cannot provide
an absolutely perfect seal. The lift arms will eventually
lower if left in the raised position during storage. It is rec-
ommended that the machine be stored with the cutting
units in the lowered position. This also prevents acci-
dental lowering of the cutting units if the lift lever (joys-
tick) is bumped while the key switch is on.
Cause
Correction
Solenoid valve(s) SV3, SV4, or SV5 have internal
leakage.
Do cartridge valve service procedure for valve in
