gearcase output shaft faces UP.
2. Remove and discard the black plastic
retaining plug from the output shaft.
See Figure 10.
3. Rotate the holder until the hole in the
holder aligns with the notch on the
gearcase. Use the long end of the hex
wrench to lock the holder and output
shaft. See Figure 10.
4. While holding the hex wrench, thread
the trimmer head onto the output shaft,
turning counter-clockwise. Using hand
pressure only, tighten the trimmer

WARNING!
A standard grass trimmer with a loop
handle should NEVER be operated
with blade-type attachments. For
blade use the trimmer must be tted
with a bicycle-type handlebar or
loop handle with a barrier bar that
is located in front of the operator to
reduce the risk of the operator from
coming in contact with the cutting at-
tachment (per ANSI B175.3). When
using a blade, the unit must also be
equipped with a harness or strap.
