1. Check the tires
Before beginning a trip, the mechanics should thoroughly inspect all four tires to ensure they are not punctured or otherwise damaged. They should also check that the tires are properly inflated and have adequate tread depth. The mechanics should make sure that the lug nuts are secure and there is no sign of rust or wear on any of the wheel components.
2. Check steering operation
The mechanics should check that the steering wheel is correctly centered, and make sure there are no cracks or damage to any of the joints in the linkage system. They should also inspect for any leaks from the power steering pump or hoses. The brakes should then be tested to ensure they are responding correctly and smoothly without any warning signs such as grinding noises or vibration when applied.
3. Check brakes
The brakes should be tested to make sure they are working properly and that all wheel cylinders have the appropriate amount of brake fluid. The mechanics should also ensure that there is no evidence of wear on the brake pads or rotors.
4. Inspect fluid levels in the engine compartment
The mechanics should check the level and condition of all essential fluids including engine oil, coolant, transmission fluid, power steering fluid, hydraulic oils and other lubricants used by the bus. Low oil pressure can cause major problems, so it is important to check for any leaks or low levels before taking off on a trip.
5. Examine belts/hoses for condition
Belts and hoses play an important role in the overall performance of a bus. The mechanics should look for any cracks or other signs of wear and tear on these components. They should also check to make sure that all hoses are securely connected and not leaking any fluids.
6. Test all lights on the bus
The mechanics should inspect all exterior lights including headlights, tail lights/brake lights, turn signals and reversing lamps. They should also ensure that the interior lighting is functioning correctly, as well as the emergency lighting system if applicable.
7. Look at windshield wipers to make sure they are working properly
Windshield wipers are essential for providing clear visibility during rain or snow storms. The mechanics should examine them closely to make sure they are in proper working order.
8. Open doors on each side of bus to check interior lighting is functioning correctly
Before taking a trip, the mechanics should open each door of the bus to check that the interior lighting is properly functioning. This will ensure that passengers have an adequate level of illumination while inside the vehicle.
9. Start engine; listen for any unusual noises while checking temperature gauge during idle time
The mechanics should start the bus and listen closely for any signs of mechanical issues such as grinding or knocking sounds coming from the engine. The temperature gauge should also be monitored to make sure it is not rising too high or too low when idling.
10. Listen closely as you drive away from stop to detect any potential mechanical issues during acceleration
The mechanics should take the bus for a test drive before beginning a trip. They should listen closely for any unusual noises coming from the engine, transmission or exhaust system as they accelerate away from a stop.
11. Check the bus horn to make sure it is working properly
This is an important safety feature that needs to be checked regularly. The mechanics should press the horn and make sure it is loud enough for other drivers to hear, and also check for any cracks in the air hose that could affect its performance.
12. Test emergency exit and emergency lighting system, if applicable
The mechanics should check to make sure that the emergency exit door is functioning properly and that all relevant signs are in place. They should also inspect the emergency lighting system, if applicable, to make sure it is working correctly.
13. Inspect all mirrors on the bus for visibility
The mirrors should be inspected for visibility, as well as their condition. Any cracked or broken mirrors should be immediately replaced to ensure that the driver has an unobstructed view of what is happening outside the vehicle.
14. Examine the fluid levels of power steering and other hydraulic systems, if applicable
The power steering fluid and other hydraulic systems should be checked for their levels and condition. If any of the fluids are low, then they should be topped off to ensure that the bus is running optimally.
15. Make sure windshield has no cracks or scratches. Clean windshield inside and out
The mechanics should clean the windshield both inside and out, as well as check for any cracks or scratches that could impair vision. This will ensure that all passengers have an unobstructed view while traveling in the bus.
