|
Do not operate or work on this product unless you have read and understood the instruction and warnings in the relevant Operation and Maintenance Manuals and relevant service literature. Failure to follow the instructions or heed the warnings could result in injury or death. Proper care is your responsibility. |
|
|
Failure to follow all safety guidelines prescribed in this document and by governing authorities and regulatory agencies may result in severe injury or death of personnel or machine damage. |
|
|
When removing a major component or attachment, ensure that it is properly blocked or secured before removing mounting hardware. An assembly that is disconnected without proper blocking may shift or fall, resulting in serious injury or death of personnel or machine damage. |
|
|
Personal injury or death can result from improper maintenance procedures. To avoid injury or death, follow the procedures exactly as stated below. |
|
|
Personal injury can result from improper handling of chemicals. Make sure you use all the necessary protective equipment required to do the job. Make sure that you read and understand all directions and hazards described on the labels and material safety data sheet of any chemical that is used. Observe all safety precautions recommended by the chemical manufacturer for handling, storage, and disposal of chemicals. |
|
|
Use caution when servicing a warm machine. Fluids (hydraulic oil, engine oil, transmission fluid, coolant, etc.) can be extremely hot. Severe burns will result from contact with hot fluids. |
|
|
Personal injury can result from hot oil or hot components. At operating temperature, oil is hot and under pressure. Hot oil can cause burns. Remove the fill cap only when the engine is stopped, and the fill cap is cool enough to touch with your bare hand. Do not allow hot oil or components to contact skin. |
|
|
Observe the safe working load limits of all lifting and blocking devices and keep a safe distance from suspended/blocked loads. Personnel may be seriously injured or killed by falling loads. |
|
|
Personal injury or death can result from sudden movement. Prevent possible injury by performing the following procedures before work begins: Move the product or equipment to a smooth, level surface. When applicable, lower equipment/work tools to the ground. Engage the parking brake, system brakes and/or hydraulic lockout control. When applicable, stop the engine and remove the ignition key. Release system pressure from pressurized systems. If applicable, block the wheels/tracks. Turn the battery disconnect switch to the OFF position and if applicable, remove the battery disconnect key. If not equipped with a battery disconnect switch, disconnect the battery cables from the battery and tape the battery clamps. Attach a “Do Not Operate” or similar warning tag at the battery disconnect switch location and as defined by site rules and/or local regulations. |

Failure to use an approved access system during installation and removal of components could result in slipping and falling which could result in personal injury or death. To prevent injury or death, use an approved access system to reach the appropriate mounting locations of the components. Do not climb on the machine. Maintain three-points of contact and/or use a safety harness. |
|
|
Do not operate the machine if any guards or covers are missing or inadequately secured. Personnel could be seriously injured or machine damage may occur. |
