Specification
Note: If at anytime during the life of a machine it is necessary to fit a new engine, then after the first 50 operating hours a new
engine oil filter must be fitted and the engine oil changed. Failure to complete this could damage the engine.
Note: Should further details be required for the refitting of the engine refer to Engine Service Manual 9803/8600.
