Final answer:
The service hose between the system and the vacuum pump should be connected securely and checked for leaks or damages.
Step-by-step explanation:
In a system with a motorized pump, the service hose between the system and the vacuum pump should be connected securely to ensure proper operation. For example, in power brake systems or bulldozers, the service hose transfers the fluid or air between the system components and the vacuum pump, allowing the pump to generate the necessary vacuum pressure for the system to function correctly. Therefore, it is essential to check for any leaks or damages in the service hose and ensure it is installed correctly to maintain the efficiency and effectiveness of the system.
