Handling fuels, oils and greases
• Caution! Scalding hazard due to hot lubricating or hydraulic oil!
• Avoid skin and eye contact with oils and greases! Wear gloves and safety goggles.
• Do not use fuels and solvents to clean your skin.
• Rectify oil and fuel leaks immediately!
• Do not harm the environment! Do not allow oils or oily wastes to enter the ground or water bodies!
• Leaked oil or fuel must be absorbed immediately using a binder and disposed of in an environmentally
compatible manner, separate from other waste!
• Even biodegradable, "environmentally friendly" oil must muss be disposed of separately, the same as any other
oil!
Residual pressure in the hydraulic system
• Caution, risk of injury! A fine hydraulic oil jet under high pressure can penetrate the skin! See a doctor
immediately if oil gets in the eyes or skin.
• Open only depressurized hydraulic systems!
• Even when a wheel loader with the lifting frame completely lowered and the engine stopped is parked on a
horizontal surface, there may be considerable residual pressure in parts of the hydraulic system.
• Residual pressure discharges gradually. If a hydraulic system needs to be opened immediately after shutdown,
you must first depressurize the system.
• For wheel loaders with lowering brake valves on lifting and/or tilting rams, the valves must be opened to lower
the lifting frame as described in section 6. "DISCHARGING RESIDUAL PRESSURE IN HYDRAULIC SYSTEM"!
Unions, pipes, hydraulic hoses
• Have leaks in the systems rectified immediately!
• Caution, risk of injury! A fine hydraulic oil jet under high pressure can penetrate the skin! See a doctor
immediately if oil gets in the eyes or skin.
• Do not use your hands to search for leaks! Use a piece of paper or cardboard to detect oil sprays.
• Do not repair damaged pipes and hydraulic hoses, but replace them with new ones immediately, even if only
moisture is visible.
Engine exhaust gases
• Caution, risk of poisoning! Engine exhaust gases are harmful to health! Do not inhale engine exhaust gases!
• If carrying out servicing and inspection work in enclosed spaces, extract the exhaust gases using an extractor
unit and ventilate the room well!
Batteries
• Caution, explosion hazard! Batteries emit explosive gases. Avoid smoking, fire or naked flames near batteries!
• Caution, explosion hazard! Do not place any tools on the battery – short circuit hazard! If the terminals are
short-circuited sparks are produced which ignite escaping gases!
• Caution, risk of injury! Battery acid is corrosive! Prevent battery acid contact with the skin, eyes, mouth and
clothing! Wear gloves and safety goggles. In case of contact with battery acid, rinse the contaminated area
immediately with copious amounts of clear water! See a doctor!
• Always remove jewelry and metal watches before working on the battery or the electrical system!
• Dispose of waste batteries in an environmentally compatible manner and separate from other waste.
