LINE INSTALLATION

This section covers both SplitLine™ line and standard

Always use Genuine Factory Parts™ 0.080 inch (2.03
mm) replacement line. Using line other than specified
may make the engine overheat or fail.
WARNING: Never use metal-reinforced
line, wire, chain or rope. These can break
off and become dangerous projectiles.
There are two methods to replace the trimming line:
• Wind the inner reel with new line
• Install a prewound inner reel
Winding the Existing Inner Reel

NOTE: Maintenance, replacement, or repair of the

In order to assure peak performance of your engine,
inspection of the engine exhaust port may be necessary
after 50 hours of operation. If you notice lost RPM, poor
performance or general lack of acceleration, this service
may be required. If you feel your engine is in need of this
inspection, refer service to any non-road engine repair
establishment, individual or authorized service dealer for
repair. DO NOT attempt to perform this process yourself
as engine damage may result from contaminants
involved in the cleaning process for the port.
