Always consult a doctor immediately even if the wound seems insignificant – otherwise serious infections could set in! Before starting maintenance work on the hydraulic system, bear in mind the following instructions: • Lower the loader unit to the ground. • Lower all hydraulically controlled attachments to the ground. • Stop the diesel engine and remove the ignition key. • Switch off the battery master switch (option)! • Use the parking brake to park the machine safely and to prevent it from rolling away! • After stopping the diesel engine, release the pressure in the hydraulic system. To do this: move all control levers of the hydraulic control valves repeatedly! • Wear protective clothes during maintenance work. • Always fill in hydraulic oil before the level gets too low. • Always fill in hydraulic oil using the filling screen. – see Filling up hydraulic oil on page 3-29! • Only use authorised oils of the same type – see Fluids and lubricants on page 3-4. • If the hydraulic system is filled with biodegradable oil, then only use biodegradable oil of the same type for filling up – observe the sticker on the hydraulic oil tank! • Immediately contact an authorised workshop if the filter insert is contaminated with metal chippings, otherwise follow-on damage can result! • Collect drained hydraulic oil and biodegradable oil in a suitable container! • Dispose of drained oil and used filters by an ecologically safe method.
