Tractor Start-Up and Engine Operation
WARNING: AVOID POSSIBLE INJURY OR DEATH
FROM A MACHINE RUNAWAY. DO NOT START
THE ENGINE BY SHORTING ACROSS STARTER
TERMINALS. THE ENGINE CAN START AND THE
MACHINE CAN MOVE WHEN THE STARTING SAFETY
SWITCH IS BYPASSED.
CAUTION: PREVENT INADVERTENT TRACTOR
OR IMPLEMENT MOVEMENT. BE SURE THE
HYDRAULIC CONTROL LEVERS ARE IN NEUTRAL
AND THE 3-POINT HITCH IS SET TO THE LOWEST
POSITION PRIOR TO STARTING THE TRACTOR
WHEN ATTACHED TO AN IMPLEMENT.
THE TRACTOR CAN MOVE AS SOON AS THE
ENGINE IS STARTED BY TURNING THE STEERING
WHEEL, EVEN WITH THE PARK BRAKE ENGAGED
AND THE TRANSMISSION IN NEUTRAL. BE SURE
ALL PERSONNEL ARE CLEAR OF THE TRACTOR
BEFORE STARTING.
Prestart Inspection
Do the following before starting the engine each day:
 . Check the engine oil level and adjust, if
necessary .
2 . Check the coolant level and adjust, if necessary .
3 . Check and clean the radiator and grill for dirt and
debris, if required .
4 . Check the transmission and hydraulic oil tank
levels and adjust, if necessary .
6 . Check differential oil levels .
7 . Inspect the condition of all belts, lights, switches,
hoses, lines, fittings, seals, tires, nuts and bolts .
Replace or tighten, if required .
8 . Check the drawbar and 3-point hitch for wear,
especially around metal-to-metal contact parts .
9 . Check wheel bolt torques .
Engine Starting
IMPORTANT: Protect the turbocharger during start-
up by not opening the throttle or accelerating above
1000 RPM until the engine oil bar graph reads in the
normal range.
Avoid excessive engine speed during warm-up .
 . Fasten your seat belt .
2 . Put the transmission in neutral .
3 . On tractors equipped with a PTO, put the switch to
the “OFF” position . A safety switch on PTO-
equipped models permits engine starting only
when the PTO is off .
4 . Engage the park brake .
5 . Check to be sure that the remote hydraulic levers
are in the neutral position .
6 . On tractors equipped with a 3-point hitch, make
sure that the hitch controls are set to the lowest
position .
7 . Set the engine throttle to the lowest position .
8 . Turn the ignition to “RUN” to activate the electrical
accessories . Observe the warning lamps to be sure
they are functioning .
9 . Engage the clutch pedal
0 . Turn the ignition to the “START” position to crank
the engine, and release when the engine starts .
The switch has a starter protection feature built-in .
If the switch is rotated to the start position, and
then released to the run position, it will be
necessary to rotate the switch to the stop position in
order to make another attempt to start the tractor .
This will prevent an accidental engagement of
the engine starter motor when the engine is already
running .
IMPORTANT: To prevent starter motor damage, never
crank the engine for more than 30 seconds. If the
engine does not start within 30 seconds, wait 2
minutes to cool the starter motor before recranking.
 . Once the engine has started, allow it to idle
and warm up before adding a working load .
IMPORTANT: Pay attention to the warning light bar
and electronic monitor for any indication of a problem.
Stop the tractor immediately and investigate the
problem.
