2.5 Maintenance

Always check that the pump is pumping oil into the sight dome.If it is not,the most likely

causes are either a blocked filter,or insufficient oil-check the oil level gauge.The oil should be

completely changed at YEARLY INTERVALS. To do this, remove the machine from the base,tip the

dirty oil away,and clean the tray and the filter on the pump. Replace the machine on its base.

Remove the machine lid and fill with 2 bottles of 800ml oil. If the needle or looper are bent,change

them immediately.
