10. Troubleshooting
Fault Check Cause Solution
Cylinder piston moves
slowly or jerkily when
activated Are the hoses
connected
properly? Air in the
hydraulic system Bleed the pump system
(see operating instructions
for hydraulic power packs)
Does the pump unit
work?
Pressure in control
table OK? Read
the pressure gauge Bleeding/depressurising
the control table (actuating
the pressure relief valves
etc., see Control Table
operating instructions)
Visual check of
hydraulic oil Hydraulic oil too
viscous because
of ambient
temperature. Replace the hydraulic oil
by oil with the relevant
viscosity
Device doesn’t
perform at its given
power Hydraulic fl uid level
in the supplying
pump adequate? Insuffi cient
hydraulic fl uid in
the pump Top up hydraulic fl uid,
deaerate
Check operating
pressure of driving
hydraulic unit Pressure supply
has too low
pressure If possible, increase
max. operating pressure
on the hydraulic unit to
max. operating pressure
of the cylinder or use
another hydraulic unit with
suffi cient max. operating
pressure.
Check device Device defective Remove the device from
service and repair it (have
it repaired)
Hoses cannot be
coupled Pressurized Set hydraulic pump to
pressureless circulation
Coupling
defective Coupling must be replaced
immediately
Hydraulic fl uid leak
on the hoses or the
fi ttings Are the hoses
defective? Leak, possible
damage Replace hoses
