Blades - Honda HHT25S Owner's Manual

BLADES

If installing a metal blade on a Honda trimmer equipped with a loop
handle, also install the optional barrier kit that includes a full shoulder
harness, a barrier bar, and a debris shield for metal blades. Follow the
safety information and installation instructions that come with the kit.
Grass/Weed Blades
Grass/weed blades, which may
be plastic or metal, are used as
an alternative to nylon
monofilament line for cutting
grass and ordinary weeds.
However, blades should never
be used for edging against
solid surfaces.
Weed/Brush Blades
These metal blades have
chisel-shaped teeth that are used for
cutting through field grass, thick weeds,
and light brush. They are not designed
for sawing woody material. The teeth
must be sharp for good results.
Brush/Wood Blades
These metal saw-tooth blades are used
for sawing through saplings, shrubs
and woody brush. The teeth must be
sharp for good results. Brush/wood
blades will also cut grass and weeds,
but they are not efficient for that
purpose.
Blade Cover
Use the blade cover to protect yourself
from injury while installing or removing
the blade and to protect the blade from
damage during storage.
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.
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 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 Honda Genuine 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.
