	IMPORTANT!

WARNING!

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 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.

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.

The unit should now be

completely assembled and ready

for use with a trimmer head.

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.
