Attachments/Accessories Operation A selection of Toro approved attachments and accessories is available for use with the machine to enhance and expand its capabilities. Contact your Authorized Service Dealer or Distributor or go to www.Toro.com for a list of all approved attachments and accessories. Note: Determine the left and right sides of the machine from the normal operating position.
Add the correct amount of gas stabilizer/conditioner to the gas. DANGER 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. Note: A fuel stabilizer/conditioner is most effective when mixed with fresh gasoline. To minimize the chance of varnish deposits in the fuel system, use fuel stabilizer at all times.
Think Safety First Please carefully read all of the safety instructions and decals in the safety section. Knowing this information could help you, your family, pets or bystanders avoid injury. DANGER Mowing on wet grass or steep slopes can cause sliding and loss of control. Wheels dropping over edges can cause rollovers, which may result in serious injury, death or drowning. A loss of traction is a loss of steering control.
Using the Rollover Protection System (ROPS) Operating the Throttle The throttle control can be moved between Fast and Slow positions (Figure 11). WARNING Always use the fast position when turning on the mower deck with the blade-control switch (PTO). To avoid injury or death from rollover: keep the roll bar installed and use the seat belt. WARNING There is no rollover protection when the roll bar is removed. • Drive slowly and carefully. • Check carefully for overhead clearances (i.e.
Important: Do not engage starter for more than 5 seconds at a time. If the engine fails to start allow a 15 second cool-down period between attempts.
