b. MX-F402/-F403
Turn two lock pins 90 degrees anticlockwise using
a flathead screwdriver and then push them off
inwards. If it is hard to do so, slightly tap the end of
driver handle.
The lock pins can also be turned by using a 4mm
hex. wrench from the inner surface of the magnet
capsule unit. In this case turn the wrench clock-
wise. Note the pins will be damaged if they are
turned in a reverse direction. After unlocking, push
it off from the outside by using a bar.
After the lock pins are removed, detach the impel-
ler unit from the magnet capsule unit by slightly
tapping the back of the impeller unit with a plastic
hammer. If the impeller unit is hardly removed,
warm it in hot water (approx. 90°C) for five minutes
and tap the back slightly. Be careful not to scald in
hot water.
The impeller unit can not be separated from the
magnet capsule unit unless the lock pins are
removed. Do not have a strong impact to remove
the impeller unit.
