Name one important guideline for using a hydraulic lift safely.

Always ensuring that the vehicle is in park or neutral and that the emergency brake is engaged before lifting is crucial for safety when using a hydraulic lift. This guideline is essential because it prevents the vehicle from rolling or shifting unexpectedly while it is elevated. When the vehicle is secured in a stationary position, it reduces the risk of accidents that could occur if the vehicle were to roll off the lift. Engaging the emergency brake provides an additional layer of security, ensuring the vehicle remains stable. This practice helps protect technicians and anyone nearby from serious injuries associated with a falling vehicle. Following this guideline fosters a safer work environment and promotes adherence to industry safety standards.
