Note:
New engines DO NOT require a running-in period. The engine/machine should be used in a normal work cycle
immediately. Glazing of the cylinder bores resulting in excessive oil consumption, could occur if the engine is gently run-in.
Under no circumstances should the engine be allowed to idle for extended periods (e.g. warming up without load).
