Brake discs are worn out
Hydraulic System
7.3
Failure Cause
Remedy
Stacker does not lift the
load (pump aggregate
operates)
load is too heavy, overload valve is actuated reduce the load
lowering valve does not close or valve face
is leaky due to soiling
clean or replace
Stacker lifts slowly or
not at all with running
pump motor, with or
without load.
pressure relieve valve not correctly adjusted
or valve face is soiled
adjust or clean valve
hydraulic pump is defective
repair or replace hydraulic pump
battery discharged or defect
charge or replace the battery
The motor pump does
not start
battery plug is not plugged in
plug in the battery plug
loose connecting cable
fix connecting cable
blown fuse
replace the fuses
defective starter relay
replace starter relay
abraded brushes in the pump motor or
weakened pressure springs
replace brushes with springs
defective pump motor
replace motor or aggregate
Lifted load is no longer
suspended
leakage in the hydraulic system
seal accordingly
not enough oil in tank
add oil
lowering valve does not close or valve face
is leaky due to soiling
clean or replace
pressure relief valve (pump) is leaky (pump
turns slowly backwards.)
clean or replace the valve
Loss of oil on the cylin-
der
sealing elements are worn out
Replace sealing elements
Discharge the stacker or the hy-
draulic system
Let oil flow out of the cylinder, re-
move screwing
Dismount the cylinder.
Disassemble the hydraulic cylinder
by unscrewing the guide piece
Remove the piston guiding
Draw the piston rod upwards out
of the guide piece and replace the
sealing elements
Use original spare parts only
Lifted load lowers too
slowly
temperature is too low - hydraulic oil is too
viscous
Warm up
soiled filter for return flow (lowering valve)
Clean
Disposal:
After placing out of service, the pallet truck parts must be disposed of or
recycled in accordance with legal provisions.
