Cleaning
When the strainer is disassembled, be sure to replace
the gasket. Install the cover and the magnet only after
sufficiently cleaning them. After being assembled, closely
check the air-tightness of the strainer.
Disassembling/ Assembling
To remove cover (1), loosen it with a spanner. After cover (1)
is removed, gasket (2), strainer (3), and gasket (4) are easily
removed in order. Wash removed strainer (3) with light oil.
Install the strainer in the reverse order of disassembling. At
that time, install gasket (2) into cover (1) first. Then, securely
tighten cover (1) to pump (5) using a spanner.

NOTE: Wrench size: 17 mm
IMPORTANT:
 Only do the cleaning and replacement of the strainer
as well as the replacement of gaskets (2) and (4)
while servicing the machine. Never attempt to
disassemble other parts.
 Gasket (4) can get caught with the shaft of pump (5),
making it difficult to remove the gasket, but do not
disassemble the shaft of pump (5). If the gasket is
difficult to remove, do not disassemble other parts
but extend gasket (4) to remove it. Use new gasket
(4) for assembling.
