Most refiners now market fuel designated as Diesel fuel to distinguish it from burner fuel. Although similar to burner fuel, the Diesel fuel is usually made

Sowever, this lighter fuel bas a lower heat content and lower viscosity. Its use may-result in loss of power and/or increased fuel consumption and shortened injection pump life. However, No. l-D fuel may be re- quired in sub-zero weather in order for the pump to maintain an adequate flow of fuel. Some refiners are marketing one grade of fuel for use in both Diesel and burner applications. This fuel, when within the spe- cifications shown below, can be safely used. However, maintain- ing the quality and suitability of 2-D ~ p e c i f i c a t i o n s , their compo- these fuels for International Diesel engines is definitely the responsibility of the supplier. Fuels lighter than kerosene will not give satisfactory performance in International Diesel engines. Although some fuels meet the Ho. . sition may be such that unsatis- factory engine wear and excessive deposits may result unless high additive lubricating oil is used. Knowledge of the fuels in your area and the types of crankcase oils required for satisfactory performance with these fuels will avoid serVice problems. doubt, see your International Harvester dealer. Diesel fuel for high speed Diesel engines is now obtainable in the U.S.A. in two grades, namely No. I-D (light fuel) and No. 2- D (heavy fuel). When in No. 2-D fuel gives the most sat- isfactory performance in Inter- national Diesel engines when the physical properties are within the limits of the following specifi- cations: Water and sediment will tend to clog the filters.

13 can Accidents be prevented with your help Rules for safe tractor operation (Prepared by the Fann Salety Committee 01 the Farm EquIpment Institute and approved by the National Safety Council. Inc.) 1. Be sure the gearshift lever is in neutral before cranking the engine. Z. Always engage the clutch gently, especially when going up a hill or pulling out of a. ditch. 3. When driving on highways, or to and from fields, be sure that both wheels are braked simultaneously when making an emergency stop. 4. Always ride on the seat or stand on the platform. Never ride on the draw- bar or the drawn implement. 5. When the tractor is hitched to a stump or heavy load, always hitch to the drawbar and never take up the slack of chain with a jerk. 6. Be very careful when working on hillsides. Watch out for holes or ditches into which a wheel may drop and cause the tractor to overturn. 7. Always keep the tractor in gear when going down steep hills or grades. 8. Always drive slowly enough to insure safety, especially over rough ground or near ditches. I. Reduce speed before making a tum or applying brakes. The hazard of overturning the tractor increases four times when speed is doubled. 10. Always stop power take-off before dismounting. 11.
