True or False: When extending the outriggers, they should extend at least three to four inches after contacting the ground, and the chassis tires should unload noticeably.

The statement is true because extending the outriggers of a piece of equipment is crucial for its stability during operation. When the outriggers are fully extended, they need to extend at least three to four inches beyond just touching the ground. This additional extension ensures that there is enough support and stabilization for the equipment, preventing any potential tipping or shifting during operation.

The unloading of the chassis tires is an important indicator of proper outrigger deployment. When the outriggers are functioning effectively, they take the load off the tires by providing the necessary support, which is often reflected in how noticeably the chassis tires unload. Properly extending the outriggers and ensuring the tires are unloaded enhances safety and operational efficiency, allowing the equipment to function as intended without risk of stability issues.

Other options suggest conditions under which the statement might not be true or imply limitations, but in standard practice, the criteria given in the statement apply universally to ensure safety and proper equipment function.
