Pay attention to other possible risks. • Never use the machine if you are tired, if you have consumed alcohol, or if you are taking other drugs or medication that can affect your vision, judgement, or coordination.
SAFETY INSTRUCTIONS Driving on Slopes Driving on slopes is one of the operations where the risk is greatest that the driver will lose control or the machine will tip over, which can result in serious injury or death. All slopes require extra caution. If you cannot reverse up a slope or if feel unsure, do not mow the slope. Do as follows: • Remove obstacles such as stones, tree branches, etc. • • Mow up and down, not side-to-side. Never drive the rider on terrain that slopes more than 10°.
SAFETY INSTRUCTIONS Children: • Serious accidents may occur if you fail to be on guard for children in the vicinity of the machine. Children are often attracted to the machine and mowing work. Never assume that children will stay put where you last saw them. • Keep children away from the mowing area and under close supervision by another adult. • Keep an eye out and shut off the machine if children enter the work area.
SAFETY INSTRUCTIONS • Allow the engine to cool before refueling. Do not smoke. Do not fill fuel in the vicinity of sparks or open flames. • If leaks arise in the fuel system, the engine must not be started until the problem has been resolved. • Store the machine and fuel in such a way that there is no risk of leaking fuel or fuel vapor leading to damages.
SAFETY INSTRUCTIONS • Never use the machine indoors or in spaces lacking proper ventilation. The exhaust fumes contain carbon monoxide, and odorless, poisonous, and lethal gas. • Stop and inspect the equipment if you run over or into anything. If necessary, make repairs before starting. • Never make adjustments with the engine running. • The machine is tested and approved only with the equipment originally provided or recommended by the manufacturer.
