WATER TEMP Gage
Shows engine coolant temperature in F and C.
6
OIL PRESS Gage
Shows engine oil pressure in psi and kPa.
7
TRANS TEMP Gage

START (Central Tire Inflation System) Switch
Pushbutton switch starts CTIS when pressed.
10
Central Tire Inflation System Rotary Selector Switch
Four-position switch used to control tire inflation/deflation for different terrain conditions.
11
Central Tire Inflation System ON/OFF Switch
Two-position switch. When switch is in ON position, CTIS will operate. Positioning switch to OFF
will shut down CTIS.
12
Tire Pressure Indicator Lights
Light indicates terrain condition selected by CTIS rotary switch. A maximum speed is associated
with each terrain condition. Lights are labeled as follows:
HIGHWAY - Maximum speed is 45 mph (72 km/h). Tire pressure :s 75 psi (517 kPa).
CROSS COUNTRY - Maximum speed is 30 mph (48 km/h). Tire pressure is 55 psi (379 kPa).
MUD, SAND & SNOW - Maximum speed is 15 mph (24 km/h). Tire pressure is 40 psi (276
kPa).
EMERGENCY - Maximum speed is 5 mph (8 km/h). lire pressure is 30 psi (207 kPa).
13
LOW AIR (Central Tire Inflation System) Indicator
Lights (red) to warn of low pressure in HET Tractor air system. This condition causes CTIS to shut
down, giving HET Tractor brake system priority for available air pressure. The CTIS automatically
resumes operation when air pressure builds up to about 110 psi (758 kPa).
14
OVERSPEED Indicator
Flashes (amber) when speed of HET Tractor is too fast for existing tire pressure as selected by
rotary selector switch.
