Maintenance
Before carrying out any maintenance work, including cleaning, the oven must be disconnected from the
electricity supply and completely cooled. In the event of a malfunction, contact only the assistance centres
authorised by the manufacturer.
CLEANING (FIG. 4)
The machine must be cleaned at the end of each use, in compliance with the hygiene regulations and to
safeguard machine operation:
• With the aid of a suitable brush, proceed with a first pass to remove residuals of flour and dough.
• Remove the two protections, the balancing device, and the two chutes from their seats.
• Release the springs (N).
• Pull the dough scrapers out (P - Q).
• Turn the adjustment levers round to position Max, the maximum open position of rollers (K).
•
Clean the machine and all parts, including those that were removed, using a sponge or cloth dampened
with water and detergent.
• Rinse sufficiently to remove all the detergent.
• Dry with kitchen paper. Go over the surfaces in contact with the dough first and then the whole machine
with a soft, clean cloth soaked with a disinfectant specific for food grade machines.
For cleaning it is forbidden to use:
•
Abrasive, corrosive or non food grade chemicals.
•
Blasts or drips of water.
•
Tools in general.
•
Abrasive powders.
• Rough or abrasive products, such as steel wool, sponges etc., that can damage the surfaces and in
particular compromise safety from a hygiene point of view.
Re-assemble in this order:
•
The dough scrapers.
•
The springs.
•
The chutes.
•
The balancing device.
•
The protections.
Make sure that all the parts have been positioned and fixed correctly.
LUBRICATING SHAFTS AND ROLLERS (FIG. 5)
The shafts and rollers must be lubricated once a year.
• Remove the protections, chutes, springs and dough scrapers.
•
Loosen the securing screws.
• Remove the back (A) first, then remove the supports (B and C).
• Pull the rollers (D, E, F, G) and joints (H, I, L, M) out.
•
Clean all parts thoroughly using a sponge, warm water, and a food grade detergent.
• Rinse sufficiently and dry with absorbent paper.
• Lubricate both shafts and holes of the rollers with a reasonable quantity of paraffin oil.
• Re-assemble and fix all the parts removed previously working in the reverse order.
