There are several cutting attachments for your 
trimmer. Use the following section to inspect, 
remove, service and install a standard (factory-
installed) cutting attachment.

Always move the engine switch to the STOP (O) 
position, and disconnect the spark plug cap 
before performing any inspection, adjustment or 
maintenance on the trimmer.

Cutting-Line Heads
All Honda trimmers come with either a manual or 
semi-matic cutting head. Read this section to 
learn how to inspect, install new line, and remove 
and install a cutting head from the trimmer.

Inspection         
Make sure the nylon line is only sticking out of the 
metal eyelets on the head. If any of the line has 
come off the spool, follow the Installing 
Replacement Nylon Line instructions in this 
section to disassemble the spool and replace the 
line.

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.

For the manual feed head, make sure the three-
sided knob is correctly tightened (page 31 ). For 
the semi-matic head, verify the spool is locked in 
place (page 33). For both head styles, check for 
any cracks in the plastic and replace any 
damaged parts.

Installing Replacement Nylon Line
First, determine which cutting-line head style is 
on your trimmer. A manual-feed trimmer head 
has a three-sided knob on the bottom of the 
head, while the semi-matic head has a spring-
loaded round button on the bottom of the head.

Do not use any kind of metal, wire or wire rope 
line on the trimmer. Use only genuine Honda 
replacement nylon trimmer line or equivalent.

Honda trimmers come standard with low noise 
line. Using non-Honda line may result in 
increased noise levels.

For original, factory-installed Honda cutting-line 
heads, use only nylon monofilament line in the 
line sizes shown below.
