This manual is used as the guidance "which contains the procedure to diagnose the machine, judge normality/abnormality, isolate the troubled area and carry out repairs soon".
The service life of the machine differs largely depending on the operation method and working conditions. To maintain the initial performance longer, daily operation, inspection and adjustment are very important.
Also, to prevent any trouble, not only proper operation but also ordinary maintenance, inspection and adjustment become important. If any trouble occurs, immediately diagnose the trouble and repair it.
To always maintain the machine under optimal conditions, read through this manual before the maintenance work and use this manual as ahelpful guide.
