The owner is responsible for training the users.
Safety • Inspect the area where the equipment is to be used and remove all rocks, toys, sticks, wires, bones, and other foreign objects which can be thrown by the machine and may cause personal injury to the operator or bystanders. DANGER 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.
Safety • 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. CAUTION Fuel tank vent is located inside the roll bar tube. Removing or modifying the roll bar could result in fuel leakage and violate emissions regulations. • Do Not remove roll bar. • Do Not weld, drill, or modify roll bar in any way. • Do Not change the engine governor setting or overspeed the engine. • Park machine on level ground.
Safety • 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. The operator is responsible for safe operation on slopes. Figure 3 1.
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.
