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.Pressurized 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 pressurized air and/or pressurized 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).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
