How do I remove the transport bolts before first use?

Loosen and remove all 4 transport bolts completely before first use, then place the provided plastic covers over the transport bolt holes by pressing on the snap hook to lock them firmly. Transport bolts that are not removed can damage the drum during operation and will cause excessive vibration and noise during spin cycles. Keep the bolt and bushing assemblies stored for later use if you need to move the washer. (Page 14)
