11.2 System malfunctions with effects on the flow limiter

Table 47

Malfunction

Cause

Remedy

Flow rate too low

•

System pressure too low

•

Check the system pressure

•

Plug-in nozzle size too small

•

Check the selection of the plug-in nozzle against the

selection table and insert the correct nozzle

•

Gear wheels are sticking, ingress of foreign

objects into the gear chamber

•

Depressurize the system, open the gear chamber,

clean the gear wheels and reinsert them (observe
arrangement and alignment). Close the gear
chamber and screw it shut

•

Cold oil, viscosity > 600 cSt.

•

Bring oil up to operating temperature. The viscosity

should be < 600 cSt.

Flow rate too high

•

Plug-in nozzle size too large

•

Check the selection of the plug-in nozzle against the

selection table and insert the correct nozzle
