onto the drip cup.
· Rotate the cage anti-clockwise so that it is fully engaged onto the drip cup
The cage should be cleaned at the end of each day.
To remove the rear splash shield.
The rear splash shield should be inspected regularly and when necessary removed
for machine washing. This should be performed by suitably trained supervisor or
maintenance department on minimum 3 monthly period, or if signs of cleaning
required.
· Ensure that the bowl support is in the lowered position, with bowl & agitator
removed, and the cage assy has been removed (see above).

remove the 3 retaining screws and place in a safe place for refitting.
· The drip cup can now be removed from the machine by carefully rotating and
lowering.
· The Drip cup should be cleaned to ensure no risk of elements dropping into
product.
· Refit the rear splash shield in reverse ensuring the screws are adequately
tightened
Note: The rear splash shield can be adequately cleaned in situ for normal applications
