Blade Removal and Installation
For loop handle models, a special optional Barrier Kit must be
installed before a blade can be used. Refer to the instructions
provided with each kit on how to install a blade on loop handle
models.
Always wear gloves and install the blade cover on the blade when
working around the blade.
A torque wrench is required to install the blade. If you do not have a
torque wrench, have a Honda trimmer servicing dealer tighten the
blade lock nut for you before using the trimmer.
If the blade lock nut is tightened too much, the output shaft can break.
If the blade lock nut is not tightened enough, the blade could come off.
In either case, it would be possible for the blade to fly off while you are
operating the trimmer.
The blade lock nut is specially designed for this application. When
replacing the lock nut, use only a genuine Honda replacement lock
nut.
BLADE SHARPENING: To avoid weakening the blade or causing
imbalance or poor cutting, the blade should be sharpened by trained
staff at a Honda trimmer servicing dealer.
BLADE REPLACEMENT: Your Honda trimmer servicing dealer has
cutting attachments that have been designed and approved for your
trimmer and are covered by a warranty. Non-Honda attachments are
usually designed for universal applications. Although aftermarket
attachments may fit on your trimmer, they may not meet factory
specifications and could make your trimmer unsafe.
1. Install the protective plastic cover that came with the blade.
2. Insert a commercially available 4 mm hex tool or equivalent fully
into the gear case hole.

3. Turn the blade until you feel the tool drop into the hole in cover
plate/spacer A. Verify the blade does not turn. The output shaft and
blade lock nut have a left-hand thread. Make sure the tool remains
in the hole, then loosen the blade nut as shown. Pay attention to
the order and orientation of the parts as they are removed.
4. Installation is the reverse of removal. Make sure you install the
blade with the cutting edges in the direction of rotation. Be sure to
align the hole in the blade with the shoulder on cover plate/spacer
A. Tighten the blade nut to the specified torque.
