How do I remove the transit bolts before using the washing machine for the first time?

Before operating the washer, you must remove 4 transit bolts along with their rubber bungs by unscrewing them with the supplied spanner and slightly twisting the bungs. After removal, close the holes with the caps supplied, and keep the 4 bolts and spanner for future use in case the machine needs to be transported again. Failure to remove the transit bolts may cause heavy vibration, noise, and malfunction. (Page 5)
