Fit the specified battery and cutting line, check the guard and work area, then hold the tool with both hands and sweep the head across grass in controlled arcs. Follow the exact model manual for line feeding, edging conversion, protective equipment and safe start-up.
The range includes both 20V MAX and 40V MAX models. Match the battery and charger to the trimmer’s exact model and platform; voltage families are not interchangeable just because the brand is the same.
Most models in the listed range use a spool of cutting line, while BLACK+DECKER also lists a cordless resin-blade trimmer. Use only the cutting head and replacement parts specified for your model.
Search the manufacturer’s service site with the model number from the tool label. That is the safest way to find a compatible spool, guard, battery, charger or manual.
