1. Care for safety labels

• Keep the safety labels clean and free from

obstructing material.

• Clean the safety labels with soap and water, and

dry the safety labels with a soft cloth.

• Replace damaged or missing safety labels with new

safety labels from your local KUBOTA Dealer.

• If a component with safety label(s) attached is

replaced with new component, make sure that new
safety label(s) is (are) attached in the same
location(s) as the replaced component.

• Attach new safety labels by applying on a clean, dry

surface and pressing any bubbles to outside edge.
