Checking procedure  
Determining the rear weight of the vehicle  
Determine the weight on the rear axle and then refer to the adjustment  
graphs.  
The allocation table enables you to choose which graph to use for  
each type of vehicle.  
Refer to the tables of different weights.  
To obtain the rear weight of the vehicle, add the following weights :  
- Rear weight of the vehicle (tank empty + 1 person).  
- Weight of fuel in the fuel tank.  
Connect the tool [1] in order to check the rear pressure values relati-  
ve to the front pressures (60 and 100 bars).  
- Weight of the options on the vehicle.  
Remove from the vehicle any object weighing more than 1 Kg.  
Rear weight of the vehicle (tank empty + 1 person)  
Note the vehicle type.  
Consult the correspondence table.  
Weight of fuel in the fuel tank  
Note the level of fuel in the vehicle and from this deduce the weight  
according to the table.
