Section 4: Operation
USE THE CORRECT DIAMETER
TRIMMER LINE
Before starting a project, examine the
grass or material you will be cutting
and trimming.
For tougher conditions, use two (or
four) sections of the thicker gauge,
.155" diameter extra-heavy duty line.
For less demanding conditions, use
two sections of the thinner gauge,
.130" diameter heavy-duty line. The
thicker line has the heft to chop
through tougher materials, while the
thinner line provides a more precise
cut. To change trimmer lines, refer to
Changing Trimmer Lines in Section 5.
NOTE: The thinner gauge line is also
recommended for use near trees or or-
namentals to help prevent girdling
(cutting the bark).
USING THE TRIMMER HEAD
CONTROL BAIL
Before starting the engine, it is essen-
tial to know how to use the Trimmer
Head Control Bail.
1. The Trimmer Head Control Bail (A,
Figure 4-3) is used to start and stop
trimmer head motion.
2. Leave the control bail in the disen-
gaged (released) position when start-
ing the engine to prevent the trimmer
head from turning when the engine
starts. See Figure 4-3.
3. When the engine is running, pull up
and hold the control bail against the
handlebar (Figure 4-4) to start rotation
of the trimmer head.
4. Let go of the control bail to stop the
trimmer head. The control bail should
spring forward to the disengaged posi-
tion. If it doesn’t, do not use the ma-
chine until the control bail has been
repaired.

the sections in this Manual on Safety,
Assembly, Features and Controls, and
Operation, you are ready to start and
