Trimmer Head
Install the Trimmer Head.
1. Turn the trimmer over so that the gear
case output shaft faces UP.
. Remove and discard the black plastic
protective cap from the output shaft.
See Figure 10.
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.
5. Remove the hex wrench.
6. Adjust the trimmer line length to reach
no further than the line cutter on the
cutting attachment shield. Trim to the
correct length if necessary.

WARNING!
A standard grass trimmer
with a loop handle should NEVER be
operated with blade-type attachments.
For blade use the trimmer must be
fitted with a bicycle-type handlebar
or 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 attachment (per ANSI
B175.3). When using a blade, the unit
must also be equipped with a harness
or strap.
The unit should now be
completely assembled and ready
for use with a trimmer head.
