3.1 Cleaning and replacing the ejector filter

CAUTION
The cleaning kit (KHW-M8860-00X) supplied with the
YG300 is exclusive use for the YG300. Do not use this
cleaning kit for other machines. If accidentally used for
other machines, this may clean away the lubricating
grease applied to the packings assembled in the
