Important
The fuel system must be bled if any of the
following 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.
Refer to Bleeding Fuel System.
Starting and Stopping the
Engine
1. Sit on seat, keep foot off traction pedal. Ensure parking
brake is engaged. Set seat and tilt steering wheel and
tower to comfortable position before starting engine.
2. Turn ignition switch to ON position. When glow plug
indicator light goes off, engine is ready to START.
Important
Do not use starting fluid.
3. Rotate ignition key switch to START position (Fig. 25).
Release key immediately when engine starts and allow
it to return to RUN position.
Note: Do not run starter motor more than 10 seconds at a
time or premature starter failure may result. If engine fails
to start after 10 seconds, turn key to OFF position. Recheck
controls and procedures, wait 10 additional seconds and
repeat starting operation.

Caution
Shut engine off and wait for all moving parts to
stop before checking for oil leaks, loose parts, or
other difficulties.

ground speed switch to LOW, disengage PTO and
cruise control switches and move lift levers and traction
pedal to neutral. Move throttle control to SLOW
position. Set parking brake and turn ignition key to OFF
position.
Important
Allow the engine to idle for 5 minutes
before shutting if off after a full load operation.
Failure to do so may lead to turbo–charger failure.
