OM2036 08/11 Safety - Section 20 Page 20-11 DURING MAINTENANCE Rules To Follow When Adding Fuel Or Oil Spilled fuel and oil may cause slipping. Clean up spills immediately. Personnel Only authorized personnel may service and repair the machine. Tighten the fuel cap and the oil cap securely. Attachments DO NOT use fuel to wash parts. Place attachments that have been removed from the machine in a safe place. Secure the attachments to prevent them from falling. Add fuel and oil in a well-ventilated area. Working Under The Machine Lower all movable work equipment to the ground, or to their lowest position, before performing service under the machine. Chock the tires of the machine securely.

DO NOT work under the machine if the machine is poorly supported. Radiator Coolant Level Keeping The Machine Clean If it is necessary to add coolant to the radiator, shut the engine off, and allow the engine and radiator to cool before adding the coolant. Spilled oil or grease, scattered tools, etc. can cause you to slip or trip. Keep your machine clean and tidy. If water gets into the electrical system, the machine may move unexpectedly and/or damage to components may occur. DO NOT use water or steam to clean any sensors, connectors, or the inside of the operator's compartment. Depress the pressure relief button on the radiator cap.

Slowly loosen the cap to relieve the pressure during removal. Use Of Lighting When checking fuel, oil, coolant, or battery electrolyte, use lighting with anti-explosion specifications. If lighting without this protection is used, there is a danger of explosion. Use extreme care when washing the electrical control cabinet. DO NOT allow water to enter the control cabinet around the doors or vents. DO NOT allow any water to enter the cooling air inlet duct above the electrical control cabinet. If water enters the control cabinet through any opening or crevice, major damage to the electrical components may occur. DO NOT spray water into the rear wheel electric motor covers.

Damage to the wheel motor armatures may occur. DO NOT spray water into the retarding grids. Excess water in the retarding grids can cause a ground fault, which will prevent propulsion.
