OM3215 10/04 Operating Instructions - Section 32 Page 32-15 Right Turn Signal Indicator This light (15, Figure 32-8) illuminates to indicate the right turn signals are operating when the turn signal lever on the steering column is moved upward. Moving the lever to its center position will turn indicator OFF. High Beam Indicator The high beam indicator (16, Figure 32-8) when illuminated, indicates that the truck head- lights are on HIGH beam. To switch headlights to HIGH beam, push the turn indicator lever away from steering wheel. For LOW beam, pull lever toward the steering wheel.
Left Turn Signal Indicator This light (17, Figure 32-8) illuminates to indicate the left turn signals are operating when the turn signal lever on the steering column is moved downward. Moving the lever to its center position will turn indicator OFF. Speedometer / Payload Meter The speedometer (18, Figure 32-8) indicates the truck speed in miles per hour (MPH), or with OPTIONAL speedometer, it may indicate truck speed in kilometers per hour (KPH). The dis- play also shows Payload Meter information. For more information, see Payload Meter in In- dex. Voltmeter The voltmeter (19, Figure 32-8) indicates the voltage of the 24V battery system.
Normal indi- cated voltage at high RPM is 27 to 28 volts with batteries in fully charged condition. When keyswitch (1) is ON and engine is NOT running, voltmeter indicates battery charge condition. Engine Oil Pressure Gauge The engine oil pressure gauge (20, Figure 32-8) indicates pressure in the engine lubrication system in pounds per square inch (psi). Normal operating pressure after engine warm up should be: Komatsu SDA16V160 or SSDA16V160 Engine: Idle - minimum: 20 psi (138 kPa), nominal: 25 psi (172 kPa) Rated Speed - minimum: 40 psi (276 kPa), nominal:
65 psi (448 kPa) Water Temperature Gauge The water temperature gauge (21, Figure 32-8) indicates the temperature of the coolant in the engine cooling system. The temperature range after engine warm-up and truck operating under normal conditions should be: 185°-207°F (85°-97°C) Fuel Gauge The fuel gauge (22, Figure 32-8) indicates how much diesel fuel is in the fuel tank. Fuel tank capacity is 1200 gallons (4543 liters).
