WARNING!
A standard grass trimmer unit with loop handle should NEVER be operated with blade-
type attachments. For blade use, the trimmer must be fitted with a bicycle-type handle-
bar or barrier bar that is located in front of the operator to reduce the risk of the operator
coming in contact with the cutting attachment. (Per ANSI B175.3). When using a blade,
the unit must also be equipped with a harness or strap.
The T272X should now be completely assembled
and ready for use with a trimmer head.
Install the Trimmer Head.
1. Turn the trimmer over so that the gear
case output shaft faces UP.
2. Remove and discard the black plastic
protective cap from the output shaft. See
Figure 9.
3. Rotate the holder until the hole in the
holder aligns with the notch on the
gear case. 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 head
firmly on the output shaft.
IMPORTANT!
The trimmer head has a left-hand thread. For
removal turn the trimmer head clockwise.
