Problem Possible Causes Procedure
Cylinder lubrication is
defective. No lubricating oil
The daily tank is empty. The ball valve
downstream of the lubricating oil filter 8.17 is
closed or the filter element is clogged. The
ball valve downstream of the measurement
tube 8.19 is closed.
Fill the daily tank. Open the
ball valve. Replace or clean
the filter element.
There is air in the cylinder lubricating system. Bleed the cylinder lubricating
system (the filter, the pump
and the pipes to the
lubricating quills).
One or more lubricating quill(s) in the cylinder
liner are blocked.
Do a check of the lubricating
quill(s). If necessary do an
overhaul of the quill(s) or
replace the defective parts.
The lubricating pump is
defective
There is no servo oil pressure, or the
pressure is too low.
Open the stop valve 4.30-5.
Do a check of the servo oil
pressure. Adjust the pressure
on the pressure reducing
valve 8.11-1 if necessary, or
do a check and adjust the set-
tings of the shut-off valve on
lubricating pump.
The 4/2-way solenoid valve, pressure
transmitter or pump body is defective.
Replace defective parts (see
the documentation of
lubricating pump
manufacturer).
3. Exhaust Valve
Problem Possible Causes Procedure
Exhaust valve The inside and / or outside piston in the ex-
haust valve is defective.
Do an overhaul, or replace.
The exhaust valve makes an
unwanted noise
The orifice or filter in the exhaust valve
control unit is clogged.
Clean the orifice or the filter
(see Maintenance Manual
5612−1).
The strainer holes in the orifice to the
exhaust valve are much larger (wear).
Replace the orifice.
The hydraulic pipe has a leak. Repair the leak, or replace
the hydraulic pipe.
Exhaust valve does not open The non-return valve 4.06 in the exhaust
valve is defective.
Do an overhaul, or replace
the non-return valve.
The piston or slide rod in exhaust valve
control unit 4.10 cannot move.
Replace the exhaust valve
control unit.
The rail valve 4.76 is defective, or a cable
connection is loose.
Replace the rail valve 4.76, or
connect the cable connection
(see 0525−1 paragraph 3).
Exhaust valve does not close The air spring pressure is too low (less than
2 bar).
Find the cause: leakage,
pressure reducing valve,
pressure in starting air bot-
tles.
The exhaust valve spindle or the inside / out-
side piston cannot move.
Replace or do an overhaul.
