screwdriver between the cutter blades
and close to the scroll to stop it
rotating. Please note, it is advisable to
use the coarse screen as this allows
room for a larger diameter
screwdriver. Undo the gearbox pulley

The pulley is a tight fit on the pinion
shaft. Use two screwdrivers to prise it
off.

Removing / replacing the planet hub assembly:

engineering adhesive, and may prove
difficult to remove. Use an 8mm

the hub spout and the hub nut, as

finish. Turn anti clockwise to remove.
* If the hub proves difficult to remove,
stand the appliance upright and tap
the end of the screw (vertical drive
shaft) with a mallet, whilst at the same
time pulling down on the hub spout.

gear, this will then transfer to the ring
gear.
