SERVICING YOUR TRIMMER
Removal and Installation
This section shows you how to remove and install
either style trimmer head from your trimmer.
1. Insert the tip of a 4 mm hex wrench, or equiv-
alent, fully into the gear case hole.
2. Turn the trimmer cutting-line head until you
feel the tool drop into the hole in the cover
plate/spacer A. Verify the trimmer head does
not turn.
3. All output shafts use left-hand threads. Make
sure the tool remains in the hole, then grasp
the trimmer head and turn in the direction of
the arrow to remove.
4. Remove spacer B and cover plate/spacer A
from the output shaft. Note the order and
orientation of each part as you remove them.
5. Installation is the reverse of removal. Always
clean debris, dirt, loose line, etc. from the
trimmer head and output shaft area before
installation. Tighten the trimmer head
securely.
