START ENGINE - CONTINUED
CAUTION
Use ether-starting aid sparingly and for cold starting purposes ONLY. Excessive ether without cranking can
cause piston and ring damage.
NOTE
Inject ether only while cranking engine or after initial start-up, until engine is running smoothly.
j.
Push ether starting aid switch down for 2-3 seconds, then release for 2-3 seconds. Operate switch at 2-3 second inter-
vals as engine is cranked. Continue to use switch at 2-3 second intervals until engine starts and is running smoothly.
k.
Release start switch when engine starts.
CAUTION
Turbocharger damage can result if engine RPM is not kept low until oil pressure is sufficient and gage is in
green range.
l.
Release accelerator pedal after engine has started.
m. If engine oil pressure does not rise within 10 seconds after engine starts, stop engine and perform troubleshooting.
After engine has started, proceed to Machine Warmup in this work package.
n.
MACHINE WARMUP
1.
Operate engine at low idle for five minutes to warm up engine. During warmup, monitor instrument panel gages for any
signs of abnormal temperatures or pressures. Shut down engine at the first sign of a problem.
2.
Continue to warm up machine as follows:
a.
If temperature is greater than 32F (0C), warmup machine for a total of approximately 15 minutes.
b.
If temperature is less than 32F (0C), warmup machine for a total of approximately 30 minutes.
c.
If temperature is less than 0F (-18C) or if hydraulic functions are sluggish, additional time may be needed.
3.
Cycle steering and machine controls to assist in hydraulic system warmup. Ensure that all are functioning properly.
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 (Neutral) to start engine, when idling
engine, and for parking. Always lock transmission in neutral when machine is left unattended in N (Neutral), 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 8:
(1) Positions 1 and 2 are suitable loading and unloading speeds. They must be manually selected.
