Place the lid on the bowl in the right position.
The appliance will only function if the arrow on the

food processor bowl and the same holds for the other
accessoires. The built-in safety lock will now be deblocked
and you can turn the appliance on.
Note that if both the blender jar and the bowl have been
correctly mounted, only the blender will function.
Important:
If the appliance is used without the blender jar, the
appliance will not function if the screw cap has not been
screwed onto the attaching hole for the blender.

− HR 7727
Remove the Poti gear (item 32) by turning it clockwise
until the arrows face each other.
The blender coupling on the motor shaft has been
−
provided with the customary left-hand thread.
The drive coupling (item 11) can be detached by
means of a hammer and a screwdriver. Strike the
screwdriver with a short sharp blow and remove the
drive coupling. Or block the acc. drive wheel (item 23)
and thereby the rotor shaft, by sticking a pin through
the hole (5 mm dia.) in the bottom plate.
The top housing (item 29) can be removed by
−
detaching the snap connections by sticking a pin (or a
screwdriver) through the small round holes (3 mm dia.)
in the bottom plate (item 27) and the housing (item 12).
The arrows in the drawing show the locations of the
holes.
In order to replace the speed selection or variomatic
−
knob, the locking lever (item 33) must be placed in its
lowest position.
The minimum speed of the HR 7727 can be set when
−
the pulse button (the button marked with an “M”) is not
mounted. The minimum speed (rpm) has been
correctly set if the motor starts automatically and
1
continues to run smoothly with the variomatic knob and
the adjustable potentiometer in the lowest setting.
The accessory drive shaft (item 15) has a locking piece
−
(item 14).
The assembly of the accessories depends on the
−
1
national version.
− For specific versions, the component configuration may
differ from the one shown on the exploded view.
However, the actual components can be distinguished
by their code numbers.
−
Make sure that all functions, including the safety
devices, are working correctly after you have
completed the repair.
