LINE INSTALLATION

This section covers both membrane line and standard
single line installation.
Always use manufacturer’s 0.095 inch (2.41 mm)
replacement line. Line other than the specified may
cause the engine to overheat or fail.

WARNING:

To prevent serious personal

injury, never use metal-reinforced line, wire
or rope. These can break off and become
dangerous projectiles. 

There are two ways to replace the trimming line:

• Wind the inner reel with new line
• Install a prewound inner reel
