Problem
Possible cause
Action
Hydraulic hoses incorrectly connected.
Connect hydraulic hoses to correct
socket.
Lift and/or implement cylinders working
in the wrong direction compared to lever
deflection.
Control cables for single lever control
incorrectly connected.
Contact your dealer.
Low hydraulic oil level.
Check and top up with hydraulic oil to
correct level.
Air leakage in hydraulic pump suction
side.
Contact your dealer.
Air in hydraulic oil (generally shown by
foaming).
Foaming due to use of wrong type of
hydraulic oil.
Read the tractor operator's manual and
top up using the recommended type of
hydraulic oil.
Low hydraulic oil level. Cold hydraulic
oil.
Check and top up with hydraulic oil.
Allow the hydraulic oil warm up to
working temperature.
Engine speed too low (hydraulic pump
speed is subsequently too low).
Increase engine speed to improve loader
performance.
Load in bucket too heavy. Material
weight exceeds loader's specified
capacity.
Reduce the load in the bucket.
Control valve cable system binds or is
damaged.
Contact your dealer.
Air in the hydraulic oil.
See “Air in the hydraulic oil”.
Hydraulic quick-release couplings not
fully engaged.
Check the couplings. Repair or replace.
Restriction in hydraulic hose or pipe
(hoses/pipes have become twisted or
pinched).
Contact your dealer.
Lifting cylinder piston unit leaks.
Contact your dealer.
Pressure relief valve working irregularly
or set too low.
Contact your dealer.
Internal leakage in control valve (bypass
flow in valve).
Contact your dealer.
Slow or jerky lifting movement.
Inadequate capacity in hydraulic pump. See “Inadequate pump capacity”.
Cold hydraulic oil.
Allow the hydraulic oil warm up to
working temperature.
Load in bucket too heavy. Material
weight exceeds loader's specified
capacity.
Reduce the load in the bucket.
Pressure relief valve set lower than
specification.
Contact your dealer.
Noise from the system's pressure relief
valve (squeaking)
Restriction in hydraulic hose, pipe or
quick-release coupling.
Contact your dealer.
Engine speed too low.
Increase engine speed.
Load in bucket too heavy. Material
weight exceeds loader's specified
capacity.
Reduce load.
Pressure relief valve set lower than
specification.
Contact your dealer.
Piston in lifting cylinders leaks.
Contact your dealer.
Insufficient lifting capacity.
Internal leakage in control valve.
Contact your dealer.
