Wear a hard hat, protective glasses, and other protective equipment, as required.
When work is performed around an engine that is operating, wear protective devices for ears in order to help prevent damage to hearing.
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 other instructions are provided, perform the maintenance under the following conditions:
The engine is stopped. Ensure that the engine cannot be started.
Disconnect the batteries when maintenance is performed or when the electrical system is serviced. Disconnect the battery ground leads. Tape the leads in order to help prevent sparks.
Do not attempt any repairs that are not understood. Use the proper tools. Replace any equipment that is damaged or repair the equipment.Pressure Air and Water
Pressurized air and/or water can cause debris and/or hot water to be blown out. This could result in personal injury.When pressure air and/or pressure water is used for cleaning, wear protective clothing, protective shoes, and eye protection. Eye protection includes goggles or a protective face shield.The maximum air pressure for cleaning purposes must be below 205 kPa (30 psi). The maximum water pressure for cleaning purposes must be below 275 kPa (40 psi).Trapped Pressure
Pressure can be trapped in a hydraulic system. Releasing trapped pressure can cause sudden equipment movement or attachment movement. Use caution if you disconnect hydraulic lines or fittings. High pressure oil that is released can cause a hose to whip. High pressure oil that is released can cause oil to spray. Fluid penetration can cause serious injury and possible death.Fluid Penetration
Pressure can be trapped in the hydraulic circuit long after the engine has been stopped. The pressure can cause hydraulic fluid or items such as pipe plugs to escape rapidly if the pressure is not relieved correctly.Do not remove any hydraulic components or parts until pressure has been relieved or personal injury may occur. Do not disassemble any hydraulic components or parts until pressure has been relieved or personal injury may
