Running-In - Beta RR 390 Manual De Uso

RuNNiNG-iN

The running-in period lasts approximately 15 hours, during which it is advisable to:
1 During the first 3 hours of operation the engine should only be used to approxi-
mately 50 percent of its power. In addition, the engine speed should not exceed
7,000 rpm.
2 For the next 12 hours of operation the engine should only be used to about 75
percent of its power.
3 Use the vehicle after properly warming up the engine.
4 Avoid travelling at constant speed (changing the speed causes the different com-
ponents to bed in evenly and more quickly).
This procedure should be followed each time piston, piston rings, cylinder, crankshaft
or crankshaft bearings are replaced.
WARNING
After the first 3 hours or 20 litres of petrol change the engine and gear oil.
• Always use high-octane unleaded petrol.
• After using the vehicle on rough ground for the first time, carefully check the
tightening of all nuts and bolts.
