WARNING: DANGER OF POISONING if oil is ingested/absorbed through the skin!
RISK OF INJURY if oil comes into contact with eyes and skin!

IMPORTANT: Adhere to the utmost cleanliness. Do not allow any dirt to enter the hydraulic system.
Using contaminated equipment to add fluid may introduce dirt particles into the fluid reservoir and significantly reduce the service life of the hydraulic steering system. Do not use any filler funnels or similar!
The fill level may only be checked or adjusted when the engine is stopped! The oil temperature should be approx. 20°C here.
Ensure that the lid is fully screwed in for the fluid level check.

NOTE: To avoid mix-ups when filling with hydraulic fluid, mark the fluid reservoir or the cap with an identification mark.
