Be sure a teenager: This Safety Alert Symbol (Figure 2) is used both in this manual and on the machine to identify important safety messages which must be followed to avoid accidents. 1.
Safety DANGER DANGER In certain conditions gasoline is extremely flammable and vapors are explosive. A fire or explosion from gasoline can burn you, others, and cause property damage. In certain conditions during fueling, static electricity can be released causing a spark which can ignite gasoline vapors. A fire or explosion from gasoline can burn you and others and cause property damage. • Fill the fuel tank outdoors on level ground, in an open area, when the engine is cold.
Safety • Never operate the mower with damaged guards, shields, or covers. Always have safety shields, guards, switches and other devices in place and in proper working condition. • Never mow with the discharge deflector raised, removed or altered unless there is a grass collection system or mulch kit in place and working properly. • Do Not change the engine governor setting or overspeed the engine.
Safety • Be aware of the mower discharge path and direct discharge away from others. • Do Not operate the mower under the influence of alcohol or drugs. • Use extreme care when loading or unloading the machine into a trailer or truck. • Use care when approaching blind corners, shrubs, trees, or other objects that may obscure vision. Slope Operation Use Extreme caution when mowing and/or turning on slopes as loss of traction and/or tip-over could occur.
Safety • Disconnect battery or remove spark plug wire before making any repairs. Disconnect the negative terminal first and the positive last. Reconnect positive first and negative last. WARNING There is no rollover protection when the roll bar is down. Wheels dropping over edges, ditches, steep banks, or water can cause rollovers, which may result in serious injury, death or drowning. • Use care when checking blades. Wrap the blade(s) or wear gloves, and use caution when servicing them.
Safety CAUTION WARNING If the ignition is in the “ON” position there is potential for sparks and engagement of components. Sparks could cause an explosion or moving parts could accidentally engage causing personal injury. Hydraulic fluid escaping under pressure can penetrate skin and cause injury. Fluid accidentally injected into the skin must be surgically removed within a few hours by a doctor familiar with this form of injury or gangrene may result.
Safety Safety and Instructional Decals • Keep all safety signs legible. Remove all grease, dirt and debris from safety signs and instructional labels. • Replace all worn, damaged, or missing safety signs. • When replacement components are installed, be sure that current safety signs are affixed to the replaced components. • If an attachment or accessory has been installed, make sure current safety signs are visible.
