MAINTENANCE AND REPAIR INSTRUCTIONS

MAINTENANCE SCHEDULE

WARNING: To prevent serious injury, never perform maintenance or repairs with unit running. Always service and repair a cool unit. Disconnect the spark plug wire to ensure that the unit cannot start.

Perform these required maintenance procedures at the frequency stated in the table. These procedures should also be a part of any seasonal tune-up.

NOTE: Some maintenance procedures may require special tools or skills. If you are unsure about these procedures take your unit to any non-road engine repair establishment, individual or authorized service dealer.

NOTE: Maintenance, replacement, or repair of the emission control devices and system may be performed by any non-road engine repair establishment, individual or authorized service dealer.

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.

LINE INSTALLATION FOR THE SPEEDSPOOL®

WARNING: Never use metal-reinforced line, wire, chain or rope. These can break off and become dangerous projectiles.

Always use original equipment manufacturer 0.095 inch (2.41 mm) replacement line. Lines other than the specified may make the engine overheat or fail.

There are two methods to replace the SpeedSpool® trimming line:

•Wind the inner reel with new line

•Install a pre-wound inner reel

Winding the Inner Reel With New Line

NOTE: It Is unnecessary to remove the bump knob to install a new trimming line.

1.Cut two pieces of 0.095 inch (2.41 mm) trimming line, 10 feet (3 m) long.

2.Hold the outer spool and turn the inner reel counterclockwise to line up the arrows on the outer spool and inner reel (Fig. 15).

WARNING: Always use the correct line length when installing trimming line on the unit. The line may not release properly if the line is too long.
