Final answer:
During a pre-trip inspection on a PIT, the four items to check in the tires are Air pressure, cuts, bulges, and embedded objects. These checks are essential for safety and operational integrity of the vehicle.
Step-by-step explanation:
When performing a pre-trip inspection on a Powered Industrial Truck (PIT), there are four specific items that should be checked to ensure the tires are in good condition. The correct choice from the options provided is b) Air pressure, cuts, bulges, and embedded objects.
- Air pressure is crucial for the proper functioning of the tire and vehicle handling.
- Inspect for any cuts that could indicate damage to the tire that may affect its integrity.
- Look for any bulges which can signal weak spots that might lead to blowouts.
- Examine the tire for embedded objects that could potentially cause punctures or further damage.
While service metrics like brand, production date, and temperature resistance might be important for tire selection and maintenance, they are not typically checked during a pre-trip inspection. The sense-based options of color, smell, and taste provided in answer choice a), and the vehicle-specific items like vehicle model provided in answer choice d), are not relevant to tire inspection.
