Viscosity Index ASTM D2270 Pour Point, ASTM D97 Industry Specifications: 140 to 152 Fuel tank capacity: 12.8 US gallons (72 l) -35°F to -46°F Use summer grade diesel fuel (No. 2-D) at temperatures above 20° F (-7° C) and winter grade (No. 1-D or No. 1-D/2-D blend) below that temperature. Use of winter grade fuel at lower temperatures provides lower flash point and cold flow characteristics which will ease starting and reduce fuel filter plugging.
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 27 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.
4. To raise the roll bar, remove the hairpin cotter pins and remove the two pins (Figure 29). CAUTION Shut engine off and wait for all moving parts to stop before checking for oil leaks, loose parts or other malfunctions. 5. Raise the roll bar to the upright position and install the two pins and secure them with the hairpin cotter pins (Figure 29). Important: Always use the seat belt when the roll bar is in the raised and locked position. Do not use the seat belt when the ROPS is in the lowered position.
4. Turn the key in the ignition switch to the On position. disengaged. The engine should stop within 2 seconds. If engine stops, the switch is operating correctly; thus, proceed to step 5 If engine does not stop, there is a malfunction in the interlock system. The electric fuel pump will begin operation, thereby forcing air out around the air bleed screw. 5. Engage the parking brake. Depress the traction pedal while engine is running and the PTO lever is disengaged.
module energizes outputs including PTO, Starter, and ETR (energize to run) solenoid. The module is divided into inputs and outputs. Inputs and outputs are identified by yellow LED indicators mounted on the printed circuit board. The start circuit input is energized by 12 VDC. All other inputs are energized when the circuit is closed to ground. Each input has a LED that is illuminated when the specific circuit is energized. Use the input LED’s for switch and input circuit troubleshooting. Figure 32 1.
5. If specific output LED is illuminated without appropriate output function, check output harness, connections, and component. Repair as required. 6. If specific output LED is not illuminated, check both fuses. 7. If specific output LED is not illuminated and inputs are in appropriate condition, install new SCM and determine if fault disappears. Each row (across) in the logic chart below identifies input and output requirements for each specific product function.
the uphill wheel stops slipping; thus, increasing traction on the downhill wheel. If independent braking is not desired, engage the lever on left brake pedal with right pedal. This provides simultaneous braking at both wheels. • Before stopping the engine, disengage all controls and move the throttle to the Slow position. Moving the throttle to the Slow position reduces high engine speed, noise, and vibration. Turn the ignition key to the Off position to stop the engine.

is moisture and contamination working its way past the protective seals. Bearings that are greased will rely upon regular maintenance to purge harmful debris from the bearing area. Sealed bearings rely on an initial fill of special grease and a robust integral seal to keep contaminants and moisture out of the rolling elements. The sealed bearings require no lubrication or short term maintenance. This minimizes routine service required and reduces the potential of turf damage due to grease contamination.
Engine Maintenance Note: Determine the left and right sides of the machine from the normal operating position. General Air Cleaner Maintenance • Check the air cleaner body for damage which could possibly cause an air leak. Replace a damaged air cleaner body.
