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.
Warm Up Machine.
2.
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 properly.
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.
Transmission Ranges.
1.
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:
Positions 1 and 2 are suitable speeds for water distribution. They must be manually selected.
Positions 3 through 6 are suitable speeds for travel. These positions are powershift selected.
d.
Downshift one position at a time when reducing engine and ground speeds. Downshift when going downhill or
operating on side slopes where greater control is needed.
e.
At gross vehicle weight, top speeds for gear positions 1 through 6 are as follows:
(1)
Position 1: 2.2 mph (3.5 kph)
(2)
Position 2: 3.6 mph (5.8 kph)
(3)
Position 3: 5.7 mph (9.2 kph)
(4)
Position 4: 8.9 mph (14.3 kph)
(5)
Position 5: 15.1 mph (24.2 kph)
WARNING
DO NOT operate machine at speeds greater than 18 mph (29 kph), in all weather and road conditions and
fully loaded. Maximum operating time at 18 mph (29 kph) is 7 hours within a 24-hour period. Failure to fol-
low this warning may cause external or internal injury due to excessive whole-body vibration.
(6)
Position 6: 21.1 mph (34 kph)
