Step-by-step explanation:
When a fault occurs while driving a forklift, the first action to take is to ensure your own safety and that of others around you. Stop the forklift and assess the situation to determine the nature of the fault. If it is a minor issue that can be fixed quickly and safely, you can attempt to resolve it yourself.
