While performing a safety walk around on the machine, which one of the following guidelines is incorrect?

1. Inspect the area around the machine and under the machine. Look for loose bolts, trash buildup, oil or coolant leakage, broken parts, or worn parts.

2. Be sure the area is free of personnel. Make sure no one is underneath the machine, around the machine, or on the machine.

3. Be sure the machine is parked on a level surface with the truck bed in the upright position.

When checking the engine coolant level on engines equipped with an overflow bottle:

1. Don’t just check coolant level in the overflow bottle. It is possible for the coolant level in the radiator to be low, even if there is coolant in the overflow bottle.

2. Check the level in the overflow bottle. The reading is accurate because the radiator will always be at the same level as the overflow bottle.

3. Check the color of the fluid in the overflow bottle and compare it to the color of the fluid in the radiator. If the color is the same, the level is accurate.

4. The level of coolant is sufficient, as long as you see fluid in the overflow bottle.

Don’t just check coolant level in the overflow bottle. It is possible for the coolant level in the radiator to be low, even if there is coolant in the overflow bottle.
