The space between the body and the frame becomes a zero clearance area when the body is lowered. Failure to install the retaining cable can result in injury or death to personnel working in this area.
Personal injury or death can occur from heavy components falling during removal or installation.Properly support the component with a suitable lifting device during removal or installation.
Personal injury can result from the sudden release of high pressure oil.Be sure the engine has been shut off for a minimum of five minutes to ensure that the accumulator pressure is zero.The accumulator is filled with dry nitrogen. Do not loosen or remove the valve or the cap from the top of the accumulator.
Pressurized System!Hydraulic accumulators contain gas and oil under high pressure. DO NOT disconnect lines or disassemble any component of a pressurized accumulator. All gas pre-charge must be removed from the accumulator as instructed by the service manual before servicing or disposing of the accumulator or any accumulator component.Failure to follow the instructions and warnings could result in personal injury or death.Only use dry nitrogen gas to recharge accumulators. See your Cat dealer for special equipment and detailed information for accumulator service and charging.
Personal injury or death can result from escaping fluid under pressure.Escaping fluid under pressure, even a very small pin-hole size leak, can penetrate body tissue and cause serious injury and possible death. If fluid is injected into your skin, it must be treated immediately by a doctor familiar with this type of injury.Always use a board or cardboard when checking for a leak.
Do not allow any dirt or foreign material to get into the hydraulic system during assembly, connection of lines, when components are filled with fluid, or during any maintenance operation.
