There is never a more important period in the life of your engine than the period between 0 and 1000 km (600 mi). For this reason, you should read the following material carefully.
Since the engine is brand new, do not put an excessive load on it for the first 1000 km (600 mi). The various parts in the engine wear and polish themselves to the correct operating clearances. During this period, prolonged full-throttle operation or any condition that might result in engine overheating must be avoided.
0-500 km (0-300 mi)
Avoid prolonged operation above 6000 r/min.
After every hour of operation, stop the engine, and then let it cool for five to ten minutes.
Vary the engine speed from time to time. Do not operate the engine at one set throttle position.
500-1000 km (300-600 mi)
Avoid prolonged operation above 8000 r/min.
Rev the engine freely through the gears, but do not use full throttle at any time. NOTICE: After 1000 km (600 mi) of operation, the engine oil must be changed, the oil filter cartridge or element replaced, and the oil strainer cleaned.
1000 km (600 mi) and beyond
The vehicle can now be operated normally.
