## ROTATING PARTS Stay clear of all rotating and moving parts. - · Wrapping or entanglement may result in serious injury or death. Keep hands, clothing and tools away from the rotating fan and running fan belts. Never operate machine without guarding in place. - · Do not drop or insert tools and others to the fan and belt. They will be blown away or damaged, resulting in serious personal injury or death. - · Always have an operator at the controls to shut down the machine if the machine needs to be running for maintenance activity or an inspection. The operator and the maintenance personnel must have a means of communication when performing these tasks. ［ <!-- image --> ## VENTILATION PRECAUTIONS Never operate the engine in an enclosed area without adequate ventilation. Engine exhaust contains carbon monoxide. Inspecting and maintaining the machine indoors or in a place with poor ventilation could cause serious injury or death. Adequate ventilation is needed when inspecting, maintaining or running the machine indoors. Fully ventilate the work area, especially when handling fuel, cleaning solvent or paint. If the natural ventilation is poor, install ventilators, fans, exhaust extension pipes or other artificial venting devices. <!-- image --> ## CONNECTING, DISCONNECTING AND STORING ATTACHMENT / EQUIPMENT To prevent serious injury or death: - · Always follow the instructions from your supervisor and the instructions in this manual when connecting or disconnecting the attachment /equipment. - · Secure the attachment /equipment to prevent them from falling over when stored. <!-- image --> 1

Know the width of your equipment to maintain proper clearance when you operate the equipment near fences or near boundary obstacles. Be aware of high-voltage power lines and power cables that are buried. If the machine comes in contact with these hazards, serious injury or death may occur from electrocution. Illustration 52 <!-- image --> Wear a hard hat, protective glasses, and other protective equipment, as required. Do not wear loose clothing or jewelry that can snag on controls or on other parts of the equipment. Make sure that all protective guards and all covers are secured in place on the equipment. Keep the equipment free from foreign material. Remove debris, oil, tools, and other items from the deck, from walkways, and from steps. Secure all loose items such as lunch boxes, tools, and other items that are not a part of the equipment. Know the appropriate work site hand signals and the personnel that are authorized to give the hand signals. Accept hand signals from one person only. Do not smoke when you service an air conditioner. Also, do not smoke if refrigerant gas may be present. Inhaling the fumes that are released from a flame that contacts air conditioner refrigerant can cause bodily harm or death. Inhaling gas from air conditioner refrigerant through a lighted cigarette can cause bodily harm or death. Never put maintenance fluids into glass containers. Drain all liquids into a suitable container. Obey all local regulations for the disposal of liquids. Use all cleaning solutions with care. Report all necessary repairs. Do not allow unauthorized personnel on the equipment. Unless you are instructed otherwise, perform maintenance with the equipment in the servicing position. Refer to Operation and Maintenance Manual for the procedure for placing the equipment in the servicing position. When you perform maintenance above ground level, use appropriate devices such as ladders or man lift machines. If equipped, use the machine anchorage poin…

You must locate this receptacle not more than 6 feet 6 inches above the floor, platform, or grade level serving the pool. - Note: In determining these dimensions, the distance to be measured is the shortest path the supply cord of an appliance connected to the receptacle would follow without piercing a floor, wall, or ceiling of a building or other effective permanent barrier. ## (b) Lighting fixtures, lighting outlets, and ceiling suspended (paddle) fans . - (i) In outdoor pool areas, lighting fixtures, lighting outlets, and ceiling-suspended (paddle) fans may not be installed over the pool or over the area extending 5 feet horizontally from the inside walls of a pool unless no part of the lighting fixture of a ceiling-suspended (paddle) fan is less than 12 feet above the maximum water level. However, a lighting fixture or lighting outlet that was installed before April 16, 1981, may be located less than 5 feet measured horizontally from the inside walls of a pool if it is at least 5 feet above the surface of the maximum water level and is rigidly attached to the existing structure. You must also protect it by a ground-fault circuit interrupter installed in the branch circuit supplying the fixture. - (ii) You must protect lighting fixtures and lighting outlets installed in the area extending between 5 feet and 10 feet horizontally from the inside walls of a pool by a ground-fault circuit interrupter unless installed 5 feet above the maximum water level and rigidly attached to the structure adjacent to or en…
