Safety Rules & Information Operating Safety Congratulations on purchasing a superior-quality piece of lawn and garden equipment. Our products are designed and manufactured to meet or exceed all industry standards for safety. Power equipment is only as safe as the operator. If it is misused, or not properly maintained, it can be dangerous! Remember, you are responsible for your safety and that of those around you. Use common sense, and think through what you are doing.
Safety Rules and Information Slope Operation You could be seriously injured or even killed if you use this unit on too steep an incline. Using the unit on a slope that is too steep or where you don’t have adequate traction can cause you to lose control or roll over. A good rule of thumb is to not operate on any slope you cannot back up (in 2-wheel drive mode). You should not operate on inclines with a slope greater than a 3.5 foot rise over a 20 foot length.
Safety Rules & Information Read these safety rules and follow them closely. Failure to obey these rules could result in loss of control of unit, severe personal injury or death to you, or bystanders, or damage to property or equipment. This mowing deck is capable of amputating hands and feet and throwing objects. The triangle in text signifies important cautions or warnings which must be followed. GENERAL OPERATION 16. Use extra care when loading or unloading the unit into a trailer or truck. 17.
Safety Rules and Information SLOPE OPERATION WARNING Slopes are a major factor related to loss-of-control and tipover accidents, which can result in severe injury or death. Operation on all slopes requires extra caution. If you cannot back up the slope or if you feel uneasy on it, do not operate on it. Control of a walk-behind or ride-on machine sliding on a slope will not be regained by the application of the brake.
SERVICE AND MAINTENANCE Safe Handling of Gasoline 1. Extinguish all cigarettes, cigars, pipes, and other sources of ignition. 2. Use only approved gasoline containers. 3.
