What is the safe procedure to follow when repacking the jack?

1. Ensure the system is disconnected

2. Use adequate supports to hold up the elevator

3. Perform a visual inspection only

4. Drain all fluids before starting

The correct answer is: Use adequate supports to hold up the elevator

Using adequate supports to hold up the elevator during jack repacking is crucial for safety. Elevators are heavy, and if the jack is removed or worked on without proper support, it can cause the elevator car to fall, posing significant risks to personnel and damaging the equipment. Proper supports ensure that the elevator remains stable and secure while the maintenance is performed, allowing technicians to work safely on the repacking process. This is an essential step in maintaining a safe working environment and preventing accidents. While disconnecting the system, conducting inspections, and draining fluids may be part of the overall maintenance process, these actions do not directly focus on the immediate safety of performing jack repacking, which is predominantly addressed through adequate supports.
