Please note

the oil leakage.
Make sure that the shock absorber is operated with an energy utilization of at
least 25 % to max. 100 %.
The recommended range lies between 50 and 80 %.

S
Take into account the fact that the viscosity of the hydraulic oil diminishes
during operation due to the friction warmth which arises.
The shock absorber can therefore break through after a long period of
operation.
