INTRODUCTION

manual for detailed information about the
controls on the engine.
FEATURES AND CONTROLS
Trimmer Head Control Bail
Pull the control bail (A, Figure 3-1) up
against the handlebar (engage bail) to
start rotation of the trimmer head. Let go
of the control bail (disengage bail) to stop
the trimmer head.
Cutting Height Settings
The trimmer head (B, Figure 3-1) is
adjustable to an infinite number of height
settings from 1-1/2" to 4-1/2" (see “Adjust
Line Cutting Height” in Section 4).
Trimming Line Mounting Plates
The two trimming lines (C, Figure 3-1) are
secured to wire-looped line holders.
Replacing the trimmer lines is easy (see
“Changing Trimmer Lines” in Section 5).
Handlebar Height Adjustment
The handlebar (D, Figure 3-1) has two
height settings (see “Adjust Handlebars”
in Section 4).
Plastic Debris Shield
A heavy-duty plastic shield (E, Figures 3-1
and 3-1A) prevents debris build-up on the
engine. The shield tilts forward for access
to the engine.
Engine Throttle Control Lever
Use this lever (F, Figure 3-1) to change
engine speeds and to stop the engine.
The throttle settings are shown on a decal
next to the lever.
Engine Recoil Starter
The recoil starter (G, Figure 3-1) is used to
pull start the engine.
Fuel Primer Button
The fuel primer button (H, Figure 3-1)
allows a cold engine to be primed for
faster, easier starting.
Keyswitch (electric start model)
The ignition keyswitch (I, Figure 3-1) acti-
vates the engine starter motor to start the
engine. The keyswitch does not have an
engine stop position. Use the Engine
Throttle Control (F) to stop the engine.
IMPORTANT: Always remove ignition key
when leaving unit unattended.
Battery (electric start model)
The battery (J, Figure 3-1) activates the
engine starter motor when the keyswitch
is turned to the start position.
Before operating your machine, care-
fully read and understand all safety,
controls and operating instructions in
this Manual, the separate Engine
Owner’s Manual, and on the decals on
the machine.
Failure to follow these instructions can
result in serious personal injury.
