SERVICING YOUR HONDA TRIMMER

CUTTING ATTACHMENTS
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.
