Topical note | Notes on self-locking nuts and bolts | ||
1 | Turn off ignition | ||
Warning | Risk of injury caused by body parts being pinched or crushed as cab is tilted | Ensure that no one is within the tilting range of the cab as it is being tilted. Always tilt the cab all the way to the end position and secure it with the safety strut. | |
2 | Tilt the cabin | ||
Notes on tilting the cab | |||
Installation: return the cabin back to working position only after performing leak test. | |||
Danger | Risk of fire/risk of explosion due to short circuit and escaping oxyhydrogen gas. Risk of (burn) injury caused by caustic burns to eyes, skin and mucous membranes from battery electrolyte/mist, short circuit and arcing. Risk of poisoning caused by swallowing battery electrolyte or absorption of lead through the skin or body orifices. Risk of death due to voltage U >= 30 V AC and U >= 60 V DC. | No fires, sparks, open flames, or smoking. Wear acid-resistant gloves, clothing, and glasses. Pour battery acid only into suitable and appropriately marked containers. | |
