Danger ! | Risk of injury. Moving parts can pinch, crush or, in extreme cases even sever extremities. | No parts of the body or limbs should be within the operating range of the mechanism when moving components. | |
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. | |
| Remove/install | ||
1 | Bring engine up to operating temperature (approx. 80°C) | Only perform a pressure test when the engine is at operating temperature. | |
2 | Switch off ignition and remove transmitter key | ||
3 | Remove glow plugs | ||
4 | Attach electrical feed lines for compression recorder (1) and crank engine with the contact switch at the compression recorder (1) | ||
Crank engine for about 5 seconds to remove combustion residues from the cylinders. | |||

5 | Attach screw-in piece (3) with check valve installed into glow plug hole for cylinder to be checked | Screw-in fitting | |
6 | Connect compression recorder (1) to screw-in piece (3) | Compression tester | |
Screw-in fitting | |||
| Check | ||
7 | Crank engine with contact switch for the compression recorder (1) until a pressure rise is no longer indicated on the compression recorder (1) | ||
8 | Carry out testing procedure in the cylinder order on remaining cylinders in the same way | ||
9 | Compare measurements obtained with permissible pressures | Compression pressure, permissible difference between the cylinders | |
Wear limit or limit value of compression pressure | |||
Installation tolerance or new value of compression pressure | |||
If pressure measured is less than minimum pressure or if permissible difference between individual cylinders is exceeded: | |||
| |||
Check for cylinder leakage | |||
10 | Install in the reverse order |
