Ref Component Description
1 Charging system
light
The engine is equipped with an alternator and voltage regulator to maintain the bat-
tery charge. The charging system warning light illuminates when there is a malfunc-
tion of the system. Although the machine will run with the light on for a short period of
time, continued operation will drain the battery and eventually cause the machine to
lose all operating functions.
If the system warning light illuminates while operating the machine in a narrow trench
or other confined area, drive machine into a safer area as soon as possible to avoid
stranding it in a hazardous or inaccessible location.
2 Glow plug light The engine is equipped with an automatic glow plug system that pre-heats the com-
bustion chambers to improve normal and cold weather starts. The glow plug light illu-
minates when the key switch and the transmitter ON-OFF switch are placed in the
ON (l) positions. It will go off when the combustion chambers are pre-heated.
Allow five minutes for the engine to warm up before operating the roller.
3 Air cleaner light The air cleaner warning light illuminates when the air filter cartridge needs to be re-
placed.
4 Hour meter The hour meter records the actual running time of the engine. Use the hour meter
when planning scheduled maintenance.
5 Engine oil pressure
light
The oil pressure warning light illuminates when oil pressure falls below the engine
manufacturer's recommended value. During such a condition, the engine will auto-
matically shut down.
6 Coolant tempera-
ture light
The cooling temperature warning light illuminates when engine coolant temperature
exceeds 230°F(110°C). During such a condition, the engine will automatically shut
down.
Allow temperature to drop below 212°F(100°C) before attempting to restart.
7 Coolant level light The cooling level warning light illuminates when coolant level is too low. During such
a condition, the engine will automatically shut down.
