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.
