Danger | Risk of death. There is a risk of death to persons located within the tilting range or underneath the raised dump body during operation. Risk of injury There is a risk of body parts being crushed or pinched when the dump body is lowered. | All persons must remain outside the tilting range of the dump body during its operation. Always secure the raised dump body with the dump body support before starting any work underneath it. | |
Warning | Risk of injury to skin or eyes from hydraulic fluid spraying out under pressure.Risk of poisoning from swallowing hydraulic fluid. | Depressurize hydraulic system completely before starting any work on it. Wear protective clothing and safety glasses. | |
