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. 

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.



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.
