What safety precautions does the manual give about performing maintenance or repairs?

The manual states that improper operation, lubrication, maintenance, or repair of the product can be dangerous and could result in injury or death. Operators must not perform any lubrication, maintenance, or repair until they have read and understood the operation, lubrication, maintenance, and repair information. Caterpillar also warns that their hazard warnings are not all-inclusive, so operators must ensure any non-recommended procedures are safe before use. (Page 2)
