Regularly check the hoses of the hydraulic system for aging and damage!
Immediately exchange damaged or aged hoses. Only use hoses for replacements
conforming to the specifications of the original hose!
For cost reasons we recommend ordering replacement hoses directly from ROPA,
because original ROPA hydraulic hoses are generally significantly more economical
than competitive products.
(1) Hydraulic oil cooler
(2) Oil cooler pump distributor gears
The fan drive of the hydraulic oil cooler automatically reverses at regular intervals. So
that soiling is removed to a great extent independently. Manual reversing is also possi-
ble (See Page 338). Consider that a soiled cooler achieves a clearly reduced cooling
performance. This substantially lowers the load bearing capacity of the machine and
therefore the lifting performance. If the hydraulic fluid gets too hot, then switch off the
engine and try to determine the cause. Usually, the hydraulic fluid cooler is soiled.
