Final answer:
Edgar should set up barriers and check the tensioning operations before beginning, calling for assistance if necessary. Proper alignment and following safety checklists indicate a correct setup, while discrepancies suggest an incorrect setup.
Step-by-step explanation:
Before Edgar begins tensioning operations with a jack, he must ensure the safety and correctness of the setup. The first step should be to set up barriers around his work area to prevent any accidents that may occur during the tensioning operations. Additionally, Edgar needs to check the tensioning operations before starting, to ensure everything is in place and correct to prevent malfunctions or accidents. Starting without any precautions or rushing to start without checking can lead to dangerous situations, and thus it is not advisable. If Edgar needs help with the setup or during the operation, he should call for assistance, ensuring he has adequate support for a safe and effective operation.
When determining if the problem is set up incorrectly or correctly, signs of a correct setup include accurate alignment, component checks, and following the operational manual or checklist. If Edgar notices that the indicator levels are off, or if there are signs of strain or improper fitting of components, he may realize the setup is incorrect. Similarly, if he follows the procedure without encountering any issues, and all safety checks are green, he can be confident that he set up the tensioning operations correctly.
