OPERATING INSTRUCTIONS FOR CATALOG # ST4500

BUMP FEED TRIMMER

LINE FEED
Your trimmer uses .065 in. (1.65 mm) diameter, ROUNDnylon line
to cut grass and weeds quickly and easily. Cutting line will wear
faster and require more feeding if the cutting or edging is done
along sidewalks or other abrasive surfaces or heavier weeds are
being cut. As you use the trimmer, the string will get shorter due to
wear. Gently bump the unit on the ground and the line will feed.
CAUTION: ALWAYS USE EYE PROTECTION.
