LRV lift control valve

Operation

83/92

300−I−9010212−E−10/08.08

Page (Chapter)

Corrective action

Cause

Fault

Attention

The UP and DOWN
spools are not
interchangeable!

DOWN pilot pin is bent

Exchange DOWN pilot
valve

Emergency−lowering
valve leaking

Operate it several times
during UP command

36 (3.1)

Check valve is leaking

Replace seal

11 (1.3)

Pressure falls rapidly

DOWN spool leaking;
clean seat and re−lap

Car sinks (with ball valve
closed)

Oil is just cooling down!

None

Leak in cylinder or
connecting line

Check/tighten connecting
hose. Renew seals, if
necessary
