How to Replace the Trimmer line
For the best performance, use a heavy gauge (0.155” diameter)
trimmer line. Cut the length of the trimmer line to 21.5". Use the
length guide, located on the shield, to make sure the trimmer
line is the correct length.
Do not allow the length of the lines to vary more than one inch.
This is important to make sure the trimmer head is balanced
and does not vibrate.
NOTE: To extend the life of the trimmer line, keep the trim-
mer 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.
1. Stop the engine. Wait for all moving parts to stop.
2. Remove the worn trimmer line from the line retainer.
3. First, thread the ends of the new trimmer line through the
outside loops. see fIGuRe 11.
4. Next, take the ends of the line, cross over the line retainer, and
thread the ends through the center hold. see fIGuRe 12.
5. Then, check to make sure that the ends of the line are even.
see fIGuRe 13.
