Craftsman 917.776741 Owner's Manual page 8

The operation of any trimmer can result in foreign objects thrown
into the eyes, which can result in severe eye damage. Always
wear safety glasses or eye shields while operating your lawn
mower or performing any adjustments or repairs. We recom-
mend standard safety glasses or a wide vision safety mask over spectacles.
