The thickness setting Indexer is adjustable to suit
the customer slicing requirements.
Important!
After servicing these machines the Indexer must
always be set to zero and check that the blade is not
exposed above the gauge plate, otherwise the
gauge plate/Indexer cam will need to be adjusted.
Sharpening Devices
Note: The sharpening should only be done when
necessary.
Procedure to sharpen blade.
Unplug the machine. Turn the Indexer to setting
number 50.
Install the sharpening device as shown above,
ensure the nurled retaining knob locates securely
into the recess on the underside of the gauge plate.
Plug in machine and switch on. Turn the Indexer

engages onto the blade and grind for 5 secs approx,
then turn Indexer back to position 50 (anti-clock-
wise) so that grinding ceases. Follow this by press-
ing the deburring wheel (finest) for 5 secs max.
