Danger ! | 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 with the safety strut. | |
Danger ! | Risk of explosion caused by fuel igniting, risk of poisoning caused by inhaling and swallowing fuel as well as risk of injury to eyes and skin caused by contactwith fuel. | No fires, sparks, open flames or smoking. Pour fuels into suitable and appropriately marked containers only. | |
Danger ! | Risk of accident from vehicle starting off by itself when engine running. Risk of injury (bruises and burns) resulting from working on the engine while it is being started or when it is running. | Secure vehicle to prevent it from starting off by itself. Wear closed and snug-fitting work clothes. Do not touch hot or rotating parts. | |
| Notes on tilting the cab | ||
| Notes on avoiding damage through contamination and foreign objects | ||
| Check | ||
1 | Tilt cab | ||
2 | Remove soundproofing | ||
3 | Open cap on fuel tank | ||
4 | Clean engine in the area of the filling valve (7) | ||
5 | Remove dust cap on filling valve (7) | ||
6 | Place shutoff valve (4.6) at position D (D) | Adapter | |
7 | Attach pressure gauge (5) with compressed air filling line (4.4) to filling valve (7) | Pressure gauge | |
Adapter | |||
8 | Attach compressed air connection (4.7) to an external compressed air supply | ||
9 | Place shutoff valve (4.6) at position E (E) | The fuel in the fuel low-pressure circuit is then pressed by this into the fuel tank. Apply compressed air to the fuel low-pressure circuit for rinsing for about 1 minute. | |
10 | Place shutoff valve (4.6) at position C (C) and relieve pressure | Catch escaping fuel at the bleed line (4.5). Repeat operation steps 9 and 10 if necessary until there is no more fuel coming out at the bleed line (4.5). | |
11 | Remove fuel lines (1, 2) on fuel level sensor (B39) |
| |
For fuel line with plug coupling (B) | |||
12.1 | Insert fuel lines (1, 2) into adapter (4.1) and secure with a slide (4.2) | Fuel line with safety clamp (A) | |
Adapter | |||
12.2 | Close off fuel lines (1, 2) on adapter (4.3) | Fuel line with plug coupling (B) | |
Adapter | |||
13 | Place shutoff valve (4.6) at position E (E) until the prescribed test pressure is reached | The prescribed test pressure is limited by the valve (4.8). | |
Pressure drop in low-pressure fuel circuit | |||
14 | Place shutoff valve (4.6) at position D (D) | ||
15 | After the prescribed test period, read off the indicated pressure on the pressure gauge (5) and compare with the test value | Pressure drop in low-pressure fuel circuit | |
If the permissible pressure drop is exceeded: | |||
| |||
Place shutoff valve (4.6) at position E (E) and localize the leakage in fuel low-pressure circuit with leak finding spray. | |||
Before removing the leakage place shutoff valve (4.6) at position C (C) and relieve pressure. Catch escaping fuel at the bleed line (4.5). | |||
Leak detection spray | |||
16 | Place shutoff valve (4.6) at position C (C) and relieve pressure | Only if no leakage was established in the fuel low-pressure circuit. | |
Catch escaping fuel at the bleed line (4.5). | |||
17 | Remove compressed air connection (4.7) on an external compressed air supply | ||
18 | Remove compressed air filling line (4.4) on filling valve (7) | ||
19.1 | Remove fuel lines (1, 2) on adapter (4.1) | Fuel line with safety clamp (A) | |
19.2 | Remove fuel lines (1, 2) on adapter (4.3) | Fuel line with plug coupling (B) | |
20 | Attach fuel lines (1, 2) to fuel level sensor (B39) |
| |
For fuel line with plug coupling (B) | |||
21 | Fill fuel low-pressure circuit on engine | ||
22 | Start engine and perform an engine test run | Allow engine to run at a higher rotational speed. | |
If engine fails to start or only runs for a brief period: | |||
| |||
Fill fuel low-pressure circuit again. | |||
23 | Stop engine and check fuel lines (1, 2) on fuel level sensor (B39) for leaktightness | Visual inspection. | |
24 | Place dust cap on filling valve (7) | ||
25 | Install soundproofing | ||
26 | Tilt back cab |
