The following work instructions apply to Meiller dumper systems installed in the Mercedes-Benz plant. In the case of other dumper systems, the operating and maintenance procedures of the relevant manufacturer must be observed. These alternative procedures may deviate from those described below. | |||
Danger! | Risk of death. There is a risk of death to persons located within the dumping area or underneath the raised dumping platform during operation. Risk of injury There is a risk of body parts being crushed or pinched when the dumping platform is lowered. | All persons must remain outside the dumping area of the dumping platform during its operation. Always secure the dumping platform with platform supports before starting any work underneath it. | |
| Checking | ||
Danger! | Risk of accident caused by vehicle starting off by itself when engine is running. Risk of injury caused by contusions and burns during starting procedure or when working near the engine as it is running | Secure vehicle to prevent it from moving by itself. | |
1 | Start engine, switch on power take-off | In models 668, 670, the "Power take-off" indicator lamp must light up. | |
2 | Operate the dumping platform switch (1) and raise the dumping platform | Remaining underneath an unsupported dumping platform is life-threatening and is therefore prohibited. The "dumping platform" indicator lamp must light up before the dumping platform is raised. | |

If damage or defects are found: rectify any damage/defects - subject to separate repair order. | |||
4 | Check condition and attachment of frame (2) and safety ropes (3). | If damage or defects are found: rectify any damage/defects - subject to separate repair order. | |
