This fuse is a 15 amp replaceable type for the protection of the backup alarm.(2) Fuse
This fuse is a 15 amp replaceable type for the protection of the horn.(3) 60 Amp Circuit Breaker (9S173)
Current from the batteries is sent through the 60 amp circuit breaker to all of the circuits in the machine.(4) 15 Amp Circuit Breaker (6N8589)
This circuit breaker is for the protection of the pressurizer. When the machine has the optional air conditioner, this circuit breaker is replaced by a 6N9349 30 amp Circuit Breaker.(5) Air Filter Indicator (7S687)
This indicator shows when the air filter elements must be cleaned or replaced. The elements must have service when the red band in the indicator stays up.(6) Light Switch (7S6402)
This is a three position switch that controls the instrument panel lights. It also controls any of the optional outside floodlights.(7) Engine Heat-Start Switch
When the heat-start switch is moved to the left (heat), the glow plugs are activated to heat the cylinders for cold weather starts. When the switch is moved to the right (start), the glow plugs and the starting motor are activated.(8) Fuse
This is a 15 amp fuse for the attachment front flood lights. It is marked spare.(9) Fuse
This is a 15 amp fuse for the attachment rear flood lights. It is marked spare.(10) Fuse
Spare.(11) Ammeter (8M7892)
The ammeter shows if the alternator is charging the batteries. (12) Water Temperature Gauge (3S4824)
During normal operation, the indicator must be in the green (normal) area (1) which is 150° to 225° F (66° to 107° C). (13) Engine Oil Pressure Gauge (4N7563)
The indicator must be in the green area (3) which is 20 to 50 psi (140 to 345 kPa) when the engine is at full load speed. It must be in the white area (2) which is 10 to 20 psi (70 to 140 kPa) when the engine is at low idle speed.The indicator must not be in the red area (1) [less than 10 psi (70 kPa)] when the engine is in operation. (14) Fuel Pressure Gauge (6N3272)
The indicator must be in the wider part of the green area (2) which is 20 to 30 psi (140 to 205 kPa) when the engine is at full load speed. It must be in the narrower part of the green area (1) which is 10 to 20 psi (70 to 140 kPa) when the engine is at low idle speed. (15) Service Meter (6N5906)
The service meter is activated when the engine is in operation and the engine oil pressure is high enough to close the engine oil pressure switch. (16) Converter Oil Temperature Gauge (2S2535)
The indicator must be in the green area (1) which is 150° to 275° F (66°
