START ENGINE - CONTINUED
CAUTION
Turbocharger damage can result if engine RPM is not kept low until EMS verifies that oil pressure is
sufficient.
j.
Release accelerator pedal after engine has started.
k.
If engine oil pressure does not rise within 10 seconds after engine starts, stop engine and perform troubleshooting.
l.
After engine has started, proceed to Machine Warmup.
MACHINE WARMUP
Perform EMS Self-Test.
1.
a.
Move panel test switch upward:
(1) Action alarm should sound.
(2) ALL indicator lights on EMS display panel should come on.
(3) Action light should flash.
b.
Release panel test switch. If the following does not occur, investigate cause:
(1) Action alarm should shut off.
(2) Selected indicator lights on EMS display panel should remain on, until all systems are operational.
(3) Action light should shut off, when all systems are operational.
2.
Warm Up Machine.
a.
Operate engine at low idle for five minutes to warm up engine. During warmup, monitor EMS alert indicators
and instrument panel gages for any signs of abnormal temperatures or pressures. Shut down engine at the first
sign of a problem.
b.
Continue to warm up machine as follows:
(1) If temperature is greater than 32F (0C), warm up machine for a total of approximately 15 minutes.
(2) If temperature is less than 32F (0C), warm up machine for a total of approximately 30 minutes.
(3) If temperature is less than 0F (-18C) or if hydraulic functions are sluggish, additional time may be needed.
c.
Cycle steering and machine controls to assist in hydraulic system warmup. Ensure that all are functioning prop-
erly.
d.
Before moving out, place transmission in R (Reverse) to ensure backup alarm functions.
OPERATE TRANSMISSION
NOTE
Refer to WP 0004 00 for a complete description of transmission controls.
1.
Transmission Ranges.
a.
N (Neutral) is normal transmission position when machine is not in use. Use N to start engine, when idling
engine, and for parking. Always lock transmission in neutral when machine is left unattended in N, parked or
stopped.
b.
R (Reverse) is used to back up machine. Machine must be brought to a complete stop before shifting into R.
Backup alarm will also sound when in reverse.
c.
To select a specific forward gear range, move transmission shift lever to positions 1 through 6. Upshift one posi-
tion at a time, as engine accelerates and ground speed increases:
(1) Positions 1 and 2 are suitable loading and unloading speeds. They must be manually selected.
