Pretrip Inspection and Daily Maintenance Pretrip Inspection Checklist 5. Tilt the cab. Examine the steering gear compo- nents. The following pretrip inspection checklist helps ensure that the vehicle components are in good working condi- tion before each trip. 6. Check the coolant level in the surge tank sight glass and check the radiator and air-to-air after- cooler cooling fins for clogging or damage. Check the radiator for coolant leaks. Pretrip inspections cannot be performed in a short pe- riod. In checklist form, the sequence below may seem to be overly time-consuming. However, careful pretrip inspections save time by eliminating stops later to ad- just items overlooked or forgotten. 7.
Check the condition of the coolant hoses and heater hoses. Each checklist step corresponds with detailed instruc- tions found under "Pretrip Inspection and Daily Mainte- nance Procedures." If any system or component does not pass this inspection, it must be corrected before operating the vehicle. Refer to the Cargo Workshop Manual for repair procedures, and to the Cargo Mainte- nance Manual for lubricant recommendations, specifica- tions, and maintenance intervals and procedures. 8.

Check the intake-air restriction indicator if it is mounted on the air intake system. 12. Check the fluid level in the hydraulic clutch fluid reservoir if equipped. NOTE: Apply the parking brakes and chock the tires. 13. Check the engine oil level. 1. Drain the air brake system air reservoirs. 14. Check the oil level in the automatic transmission if equipped. 2. Inspect the batteries and battery cables. 15. Check the fuel water separator, if equipped, for contaminants. 3. Check the fluid level in the windshield washer res- ervoir. 4. Check the front hub lubricant level if equipped with oil-lubricated wheel bearings. 16. Lower the cab. Close the drain valves on the air brake system air tanks.
