11 1.3 CHASSIS ASSEMBLY The Chassis Assembly includes the cab, truck body and frame, engine, transmission, drive lines, front and rear axles, steering, fuel, brake, and electrical systems and wheels and tires. Also included with the chassis are miscellaneous items related to the operation of the truck, such as light and sound systems, power converter, bumpers, towing hooks and mirrors Controls and Instruments The controls and instruments necessary for the road operation of the truck, for transfer of power to the pump and ladder, and for the operation of light and sound systems are located in the cab of the truck. The following sub-paragraphs provide a brief description of the function of each component in the truck cab (for component locations, refer to Figures 1-1 through 1-4). 1. Ignition Switch - When switched on, a green lamp in the switch lights, indicating the ignition system is on. 2. Headlight Switch - Operates the headlights, tail lights, instrument panel lights and running lights. 3. Air Cleaner Restriction Indicator - Turns red when the air cleaner element requires servicing. 4. Engine Coolant Temperature Gauge - Indicates the temperature of the coolant. -7-

12 5. Warning Lights - Indicate a malfunction in one of five systems: low engine oil pressure, high engine coolant temperature, low air pressure in front air system, low air pressure in rear air system, and high automatic transmission fluid temperature. The warning light is mounted next to the gauge for each system being monitored. In addition to the warning light, the operator is alerted to malfunctions by a loud warning buzzer. If the malfunction is in one of the "vital circuits" (low engine oil pressure, high engine coolant temperature, or high automatic transmission fluid temperature), the buzzer will sound a steady, piercing alarm. If the malfunction is low air pressure in either the front or rear system, the buzzer will sound an intermittent alarm. 6. Voltmeter - Indicates battery conditions. 7. Ammeter - Indicates amount of charge or discharge. 8. Engine Oil Pressure Gauge - Indicates the pressure of the lubricating oil in the engine. 9. Red Parking Brake Override Button - Used in emergencies to release the parking brake when the ladder is not on its bed. Press and hold down the button and then move the truck. When the button is released, the parking brake will automatically re-set. 10. Tachometer - Indicates the engine speed in revolutions per minute. 11. Hourmeter - Indicates the number of hours the engine has operated. The hourmeter is activated by engine oil pressure. It will not register when the master switch is on unless the engine is running. -8-

13 12. Turn Signal Indicator Lights - Blink to indicate the direction of turn when the Turn Signal Lever is used. 13. Parking Brake Light - Will light when the parking brake is applied. It will remain lit until the yellow park brake button (Item 23) is pushed to release the brakes. 14. Headlight High-Beam Indicator Light - Glows a bright blue when the headlights are on high-beam. 15. Speedometer/Odometer - Indicates the truck speed in miles per hour and kilometers per hour. The odometer records the total number of miles travelled. 16. Fuel Level Gauge - Indicates the amount of fuel in the fuel tank. 17. Air Pressure Gauge - Front Brakes - This gauge works in conjunction with the low-air warning lights and buzzer. Normal operating pressure is psi. 19. Automatic Transmission Oil Temperature Gauge - Indicates the temperature of the oil in the transmission. Normal operating range is 160 degrees to 220 degrees F. Maximum allowable temperature is 250 degrees F. 20. Air Pressure Gauge - Rear Brakes - This gauge works in conjunction with the low-air warning lights and buzzer. Normal operating pressure is psi. 22. Black Shut-off Handle - Pull out to stop engine. Push in to start. -9-

15 32. Pump Power Shift Control - Controls the transfer of power from the truck drive train to the Hale pump. In the OUT position, the pump is engaged; when pushed IN, the truck drive train is engaged. 33. Jacobs Brake Control Switch - Controls Jacobs engine brake. 34. Ladder PTO Switch - ENGAGED/DISENGAGED switch engages the power-take-off (PTO) controlling the ladder hydraulics. 35. Master Switch Indicator Light - Lights when the Master Battery Selector Switch is turned to "BATTERY 1". 36. Ladder PTO Indicator Light - When lit, indicates the Ladder PTO is engaged. 37. Engine Start Button - There are two engine start buttons. Either may be used to start the engine providing it has been selected by the Master Battery Selector Switch. The Master Battery Select Switch and Automatic Transmission Gear Selector are located on the floor of the cab to the right of the driver s seat (see Figure 1-3). The start button that is energized will be indicated when its associated indicator light is lit. 38. Master Switch Indicator Light - Lights when the MaSTER Battery Selector Switch is turned to "BATTERY 2". 39. Engine Start Button - Energized when Indicator Light is on. 40.
