Danger! | Risk of injuries by pinching and crushing when tilting the cab | During cab tilting, nobody is to be in the cab tilting area. Always tilt the cab to its final position and latch. | |
Danger! | Risk of injuries on skin and eyes by hydraulic fluid ejected at high pressure. Risk of poisoning by ingestion of hydraulic fluid. | Before starting the jobs in the hydraulic system, relieve the pressure of the system. Use protection clothes and glasses. | |
Danger! | Risk of accident by automatic engine starting. Risk of injuries by crushing and burns at contact during the engine starting procedure or with the engine running. | Protect the vehicle against accidental displacement. Use closed and tight fitting work clothes. Do not touch hot or rotating parts. | |
| In assembly jobs in the steering, to prevent operation faults, it is necessary to observe extreme cleansing conditions. | For the cleaning jobs only lint-free rags or paper towels may be used. | |
