Saw Blade
The U-type handlebar models are shipped with a manual nylon cutting-line head installed on the
trimmer. If the saw blade is needed, move the ignition switch to the STOP (O) position and disconnect
the spark plug cap from the spark plug. Wear protective gloves when working around the cutting-line
head and saw blade.
Cutting-Line Head Removal
1. Align the gear case hole with the groove in
cover plate/spacer A. Insert a 4 mm hex
wrench or equivalent into the gear case hole
to prevent the left-hand threaded output shaft
from turning.
2. Hold the wrench and rotate the cutting-line
head in the direction of the arrow and remove
the cutting-line head assembly.
Remove the cutting-line head as an
assembly. Do not remove the knob. Refer to
page 31 for a cutting-line head assembly
drawing.
