How to Replace the Trimmer Lines
Maintenance
(Continued)
• Save all instructions
When the trimmer line becomes worn to half the original
length, replace the trimmer line. For the best performance,
use a heavy gauge 0.155 in. [4 mm] trimmer line.
1. Stop the engine. Wait for all moving parts to stop.
Disconnect the wire from the spark plug.
2. Remove the worn trimmer line from line retainer.
3. Cut the length of the trimmer line to 21.5 in. [546 mm].
Use the length guide; located on the shield to make sure
the trimmer line is the correct length. (See Figure 14)
NOTE:
Do not allow the length of the lines to vary more than
one inch. Make sure the trimmer head is balanced and does
not vibrate.
4. Thread the ends of the new trimmer line through the
outside loops. (See Figure 15)
5. Take the ends of the line, cross over the line retainer,
and thread the ends through the center hole.
(See Figure 16)
6. Then, check to make sure that the ends of the line are
even. (See Figure 17)
7. Follow same steps for line on alternate side.
IMPORTANT:
To extend the life of the trimmer line, keep the
trimmer line moist. If not kept moist, the nylon trimmer line
will become dry and brittle. Keep extra trimmer line in a can
of water. The line will then stay flexible and easy to change.
A flexible line will also last much longer.
