INSTRUCTION MANUAL
Trimmer/edger
KEY INFORMATION YOU SHOULD KNOW:
• The guard must be installed before trimming or edging - if not, the motor will overheat.
• When replacing the line, use only .065 inch diameter ROUND line (B&D Model #AF-100 is
recommended) - otherwise the trimmer will not function properly.
• Do not bump the feed head against the ground - it will disrupt the automatic feed mechanism.
• Always use the cord retention feature
