MAINTENANCE SAFETY Never service the Bobcat Skid- Steer Loader without instructions. Have good ventilation when welding or grinding painted parts. Wear dust mask when grinding painted parts. Toxic dust and gas can be produced. Avoid exhaust fume leaks which can kill without warning. Exhaust system must be tightly sealed. Stop, cool and clean engine of flammable materials before checking fluids. Never service or adjust loader with the engine running unless instructed to do so in the manual. Avoid contact with leaking hydraulic fluid or diesel fuel under pressure. It can penetrate the skin or eyes. Never fill fuel tank with engine running, while smoking or when near open flame. Disconnecting or loosening any hydraulic tubeline, hose, fitting, component or a part failure can cause lift arms to drop. Do not go under lift arms when raised unless supported by an approved lift arm support device. Replace it if damaged. Keep body, jewelry and clothing away from moving parts, electrical contact, hot parts and exhaust. Wear eye protection to guard from battery acid, compressed springs, fluids under pressure and flying debris when engines are running or tools are used. Use eye protection approved for type of welding. Keep rear door closed except for service. Close and latch door before operating the loader. Never work on loader with lift arms up unless lift arms are held by an approved lift arm support device. Replace if damaged. Never modify equipment or add attachments not approved by Bobcat Company. Lead-acid batteries produce flammable and explosive gases. Keep arcs, sparks, flames and lighted tobacco away from batteries. Batteries contain acid which burns eyes or skin on contact. Wear protective clothing. If acid contacts body, flush well with water. For eye contact flush well and get immediate medical attention. Use the correct procedure to lift or lower operator cab. Cleaning and maintenance are required daily.
