TORQUE: 2.5 ft-lb (3.4 N·m)
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.
A cutting-line head containing nylon monofilament line and a debris
shield with a cutoff knife is standard equipment. The shield’s cutoff
knife automatically removes any excess line that is released from the
cutting head.
The U-type handlebar trimmers are supplied with two different debris
shields. Use the debris shield with the cutoff knife when the
cutting-line head is installed.
Nylon monofilament line is suitable for cutting grass and ordinary
weeds, but not brush and woody growth.
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 22). For the semi-matic head, verify the
spool is locked in place (page 23). 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 Honda Genuine 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.
See page 29 for replacement parts information.
