Modification notes
| Remove/install | ||
Danger! | Risk of injury to skin or eyes caused by hydraulic fluid spraying out under high pressure. Risk of poisoning caused by swallowing hydraulic fluid | Depressurize hydraulic system completely before starting any work on the system. Wear protective clothing and safety glasses. | |
Danger! | Risk of injury to skin and eyes caused by scalding from contact with hot coolant spray. Risk of poisoning caused by swallowing coolant. | Do not open cooling system unless coolant temperature is below 90°C. Open cap slowly and release the pressure. Do not pour coolant into beverage containers. Wear protective gloves, protective clothing and safety glasses. | |
| Notes on coolant | ||
1 | Open maintenance flap | ||
Danger! | Risk of injury caused by body parts being pinched or crushed as cab is tilted | Ensure that no one is within tilting range of cab as it is being tilted. Always tilt cab all the way to end position and secure with safety strut. | |
