Lubricate
When the trimmer line becomes too short or worn,
change to a new trimmer line as follows:
• Remove the worn trimmer line and replace with
new trimmer line packed with your string trimmer
mower. Always use 0EM-743-0113 when
purchasing additional trimmer line.
• Fold new trimmer line in half and thread the ends of
line through the loop from the inside out without
going all the way through the loop. See Figure 6.
• Slide the loop end of the trimmer line under the
metal tab and secure in place by crossing and
pulling tight on the ends of the line.

NOTE: When tipping the unit or emptying the fuel tank,
keep the air filter side of engine up. Never tip the string
trimmer mower more than 90 degrees and do not leave
the unit tipped for any length of time. Oil can drain into
the upper part of the engine causing a starting problem.
