inch (13 mm) from the groove in the dipstick (Figure 30), add enough fluid to raise level to groove mark. Do not overfill by more than 1/2 inch (13 mm) above groove. reputable manufacturers who will stand behind their recommendation. Checking the Hydraulic System The front axle housing acts as the reservoir for the system. The transmission and axle housing are shipped from the factory with approximately 5 quarts (4.7 l) of high quality hydraulic fluid.
Starting/Stopping Engine Important: The fuel system must be bled if any of the following situation have occurred. • Initial start up of a new machine. • Engine has ceased running due to lack of fuel. • Maintenance has been performed upon fuel system components; i.e., filter replaced, separator serviced, etc. Figure 31 1. Check plug 2. Fill/check plug (one on each end of axle) 3. Fill plug Refer to Bleeding The Fuel System. Check Bidirectional Clutch Lubricant (Models 30627 & 30631 only) 1.
Bleeding Fuel System engine does not start, air may be trapped between injection pump and injectors; refer to Bleeding Air From Injectors. 1. Park the machine on a level surface. Make sure fuel tank is at least half full. 2. Unlatch and raise hood. Checking the Interlock Switches Under certain conditions, diesel fuel and fuel vapors are highly flammable and explosive. A fire or explosion from fuel can burn you and others and can cause property damage.
Operating Characteristics PTO lever to ON. The engine should stop within 2–3 seconds. If the engine does not stop, there is a malfunction in the interlock system that should be corrected before beginning operation. 5. Engage the parking brake. Depress the traction pedal while engine is running and the PTO lever is disengaged. The engine should stop within 2 seconds. If engine stops, the switch is operating correctly; thus, continue operation.
Before stopping the engine, disengage all controls and move throttle to SLOW. Moving throttle to SLOW reduces high engine rpm, noise, and vibration. Turn key to OFF to stop engine.
