The Air Cleaner is not fitted as standard.
After every 5,000 miles running (approximately) the air cleaner should be removed for cleaning and re-oiling. It should not be dismantled, as if it is taken apart and the wire element isunwound it may not be possible to replace this satisfactorily, so as to get an even ﬂow of air through it all round.
The entire ﬁlter should be washed in clean petrol until all accumulated dirt has been removed and should afterwards be allowed to dry thoroughly inside and out. Before reﬁtting immerse the ﬁlter in clean engine oil (Grade SAE50) and after draining off surplus oil and wiping clean externally reﬁt it to the machine. No other attention is needed.
