Attachments/Accessories Think Safety First A selection of Toro approved attachments and accessories are available for use with the machine to enhance and expand its capabilities.
In certain conditions, gasoline is extremely flammable and highly explosive. A fire or explosion from gasoline can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any gasoline that spills. • Never fill the fuel tank inside an enclosed trailer. • Do not fill the fuel tank completely full. Add gasoline to the fuel tank until the level is 1/4 to 1/2 inch (6 to 13 mm) below the bottom of the filler neck.
Important: Do not use fuel additives containing methanol or ethanol. In certain conditions during fueling, static electricity can be released causing a spark which can ignite the gasoline vapors. A fire or explosion from gasoline can burn you and others and can damage property. Add the correct amount of gas stabilizer/conditioner to the gas. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline.
Filling the Fuel Tank Setting the Parking Brake Note: Do not fill the fuel tank completely full, this will allow gasoline to expand. 1 2 1. Shut the engine off and set the parking brake. 2.

Using the Side Discharge The mower has a hinged grass deflector that disperses clippings to the side and down toward the turf. G010230 2 1 3 Without a grass deflector, discharge cover, or complete grass catcher assembly mounted in place, you and others are exposed to blade contact and thrown debris. Contact with rotating mower blade(s) and thrown debris will cause injury or death. • Never remove the grass deflector from the mower because the grass deflector routes material down toward the turf.
Cut 1/3 of the Grass Blade the mower, cutting quality will eventually become unsatisfactory. It is best to cut only about 1/3 of the grass blade. Cutting more than that is not recommended unless grass is sparse, or it is late fall when grass grows more slowly. Blade Maintenance Maintain a sharp blade throughout the cutting season because a sharp blade cuts cleanly without tearing or shredding the grass blades.
