Using diesel fuel with sulphur content above 0.50% requires more frequent oil changes as noted in the maintenance schedule. The use of diesel fuel with a sulphur content above 1.3% is not recommended. Diesel Fuel Selection Chart Do not use Number 2-D fuel at temperatures below -7°C(20°F). The cold temperatures will cause Number 2-D fuel to thicken, which may keep the engine from running. (If this happens, contact your Buhler Versatile dealer.) For the best fuel economy, use Number 2-D whenever the temperature will permit. To be sure a fuel meets the required properties, enlist the aid of a reputable fuel oil supplier. The responsibility for clean fuel lies with the fuel supplier as well as the fuel user. General Final Boiling Cetane Sulphur Content Fuel Class Point (Max.) Temp. Range (Min.) (Max.) No. 1-D 288°C (550°F) -7°C(20°F) 40* 0.30% and below No. 2-D 357°C (675°F) -7°C(20°F) 40 0.50% and above *When continually operating at low temperatures or high altitude, a minimum cetane of 45 is required. Cummins position relative to use of Biodiesel fuel At this time biodoesel blends up to B5 are the only blends approved for use in all Cummins engines for both On Highway and Off highway markets. B5 which is a blend of 5 percent pure biodiesel (B100) and 95 percent standard petroleum diesel has demonstrated to have no impact on engine performance, durability or maintenance. The industry standard known as ASTM D6751 defines the specifications for B100. However, this standard currently lacks a specification for stability. Without a specification, the quality of the fuel in blends higher than B5 could degrade to a point which could be damaging to engines. Cummins is supporting industry efforts to add a stability specification to the current ASTM standard, and continues to evaluate the impact of these blends on durability of engines. Until this spec is developed and tested, other blends of biodiesel will be unsuitable for use in Cummins On highway and Off highway engines. 3-3 SECTION 3 -LUBRICATION AND MAINTENANCE ADDING DIESEL FUEL Fuel can be added to either tank. The two tanks are connected via a crossover tube. Total usable capacity of the two tanks is 870L (230 U.S. gallons). When filling the tanks, make sure the vent, 1, located at the rear of the cab, behind the washer fluid reservoir, is unobstructed. CAUTION: DO NOT OVER FILL THE TANKS TO CAPACITY. EITHER FILL TO BOTTOM OF FILLER NECK OR USE THE ELECTRONIC INSTRUMENT CONTROL SYSTEM TO AID IN REFUELING. WHEN THE ALARM SOUNDS A SOLID TONE, THE TANK IS FULL. ALLOW ROOM FOR EXPANSION. FUEL EXPANSION OF OVER FILLED TANKS CAN RESULT IN FUEL ENTRY TO ENGINE CYLINDERS AND ACCOMPANYING HYDRAULIC LOCK. IF THE ORIGINAL FUEL TANK CAPS ARE LOST, REPLACE THEM WITH BUHLER VERSATILE CAPS AND TIGHTEN SECURELY. To add fuel to the tractor, follow the steps below: 1. Clean the area around the fuel cap(s) to prevent debris from entering the fuel tank. 2. To remove the cap, turn handle, 1, in the center of the cap counterclockwise until loose and pull the cap from the tank. Place it in a clean area during refueling. NOTE: With the engine off, and the ignition switch in the “RUN” position, the fuel fill mode of the Electronic Instrument Control System will be operational and will assist in refueling procedures. Refer to “Electronic Instrument Control System” in Section 2 for further information. 3. After filling the tank, replace and tighten the fuel cap. The cap has a locking tab for additional security. 1 Figure 3-1 1 Figure3-2 3-4 SECTION 3 -LUBRICATION AND MAINTENANCE REMOVING SHIELDING TO GAIN ACCESS TO COMPONENTS FOR INSPECTION AND MAINTENANCE ENGINE ACCESS In order to perform service, inspection and lubrication operations to the tractor, it may be necessary to open or remove various panels and shields. IMPORTANT: After performing work on the tractor, install all safety shields before operating the tractor. OPENING THE HOOD PANELS To provide easy access to the engine, each hood side panel swings open vertically. There is an external latch, 1, that releases the panel. Each panel is held open by a single gas strut. Close the hood panels by pulling downward from the side of it and keeping a steady pressure on the panel. The gas strut will collapse and the panel will go over center and latch. Do not force the panel down against the gas strut. 1 REMOVING THE HOOD PANELS The hood panels can be removed easily if greater access is required for a maintenance or service operation. 1. Remove the hairpin clip, 1, from the front pivot stud. 2. Unhook the gas strut from under the hood. 3. Slide the panel front and clear the front pivot stud. 4. Slide the panel toward the rear of the tractor to remove the panel from the rear pivot stud. 5. Set the panel off to the side out of the way. To reinstall the panels, reverse the above procedure. 1 Figure 3-3 Figure 3-4 3-5 SECTION 3 -LUBRICATION AND MAINTENANCE BATTERY ACCESS The batteries are located on top of the right side fuel tank.
