Adding Fuel Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendation. Material Properties: Viscosity, ASTM D445 Viscosity Index ASTM D2270 Pour Point, ASTM D97 Industry Specifications: Fuel tank capacity: 72 liters (12.8 US gallons) Use only clean, fresh diesel fuel or biodiesel fuels with low (<500 ppm) or ultra low (<15 ppm) sulfur content. The minimum cetane rating should be 40.
DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Never fill the fuel tank inside an enclosed trailer. • Never smoke when handling fuel, and stay away from an open flame or where fuel fumes may be ignited by a spark. • Store fuel in an approved container and keep it out of the reach of children.
Using the Rollover Protection System (ROPS) WARNING To avoid injury or death from rollover: keep the roll bar in the raised locked position and use the seat belt. Ensure that the rear part of the seat is secured with the seat latch. Figure 28 1. Fill/check plug (one on each end of axle) WARNING There is no rollover protection when the roll bar is in the down position. • Lower the roll bar only when absolutely necessary. • Do not wear the seat belt when the roll bar is in the down position.
