Safe Operating Practices The Toro warning system in this manual identifies potential hazards and has special safety messages that help you and others avoid personal injury, even death. DANGER, WARNING and CAUTION are signal words used to identify the level of hazard. However, regardless of the hazard, be extremely careful. This product is capable of amputating hands and feet and throwing objects. Always follow all safety instructions to avoid serious injury or death.
• The engine, blade, and self–propel drive (self-propelled model) are designed to stop when the control bails are released. Ensure that the control and brake function properly before each use of the mower. • Do not touch the engine while it is running or shortly after it is stopped because it will be hot enough to cause a burn. • Refuel only when the engine is cool. • Disengage the self-propel mechanism or drive clutch (self-propelled models) before starting the engine.
Safety and Instruction Decals Safety decals and instructions are easily visible to the operator and are located near any area of potential danger. Replace any decal that is damaged or lost.
