OPERATING INSTRUCTIONS

To reduce the chance of material wrapping around the blade, follow these steps:

WARNING: Do not sharpen the cutting blade. Sharpening the blade can cause the blade tip to break off while in use. This can result in severe personal injury to yourself or others. Replace the blade.

• Cut at full throttle

• Swing the unit into material to be cut from your left to your right (Fig. 29)

• Avoid the material just cut as you make the return swing

WARNING: Do not clear away any cut material

 

with the engine running or blade turning. To avoid

 

serious personal injury, turn off the engine. Allow

 

the blade to stop before removing materials

MAINTENANCE AND REPAIR INSTRUCTIONS

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.

MAINTENANCE SCHEDULE

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.
