Blade
Blade Inspection
Always wear gloves when working around the
blade. Before each use, check the blade for wear
and damage, and check the tightness of the
blade lock nut. Examine the entire head area,
including the debris shield, and clear or clean it
free from dirt, debris, loose string, wire, or any
other foreign materials.
WARNING

A worn, damaged or cracked blade can break,
and pieces of the damaged blade can become
dangerous projectiles.
A dull blade is more likely to snag and thrust
(kickback).
Inspect the blade regularly, and do not operate
the trimmer with a dull, worn, or damaged
blade.
NORMAL
BENT
A dull blade can be sharpened, but a blade that is
worn out, bent, cracked, chipped, or otherwise
damaged must be replaced.
When a blade needs sharping or replacement,
take the trimmer to a Honda trimmer servicing
dealer. Or, if you have a torque wrench, you can
remove and install a blade yourself.

Blade Removal & Installation
(HHT31SUNBA only)
For models other than the HHT31SUNBA, 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 HHT31SUNBA 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.
