Troubleshooting
If problems occur, do not lift the load any further.
Fault Cause

pumping action
Load excessive, pressure limiting valve in operation
Reduce load
Leak in hydraulic system
Carry out required maintenance
Non-return valve fails to close, or valve seat is soiled
Clean or replace
Piston lowers independently of
pump action
Release valve fails to close, or valve-seat seal is
contaminated with oil
Clean or replace
The lifting arm does not fully
extend
Too little oil in the hydraulic system
Check the oil level and top it up if
necessary
Jack losing oil
Worn seals
