Correcting grass bind
Caution: Always remove the battery before correcting grass bind to avoid accidental activation of the trimmer head.
Certain types and lengths of grass can sometimes be caught between the trimmer head and the spindle. When this happens, the grass quickly winds around the shaft clogging the space between the shaft and the trimmer head and slowing or stopping the trimmer head rotation. This condition is called grass bind.
To correct grass bind, remove the trimmer head and clean all grass or weeds from the spindle. If necessary, cut the grass or weeds free. Once the spindle is cleared, replace the trimmer head.
Battery pack
Warning: There are no user serviceable parts inside the battery pack. Do not disassemble.
Lithium ion batteries have a predetermined operating life. If the amount of cutting time per charge decreases noticeably, the battery pack is at the end of its useful life and should be replaced.
•Make sure the battery pack, including the contacts, is clean, dry, and has no signs of puncture, impact, or other damage. Broken batteries can cause fires or emit hazardous chemicals.
•Clean dirty contacts with a soft, dry cloth. Dirt or oil can cause a poor electrical connection resulting in loss of power.
Charger
•Unplug the charger from the electrical outlet.
•Clean dirty contacts with a soft, dry cloth.
