rotation and prevent forcing the terminal.
Note: Forcing any of the terminals of the heating elements during connection /
disconnection of electrical cables, irretrievably jeopardizes the entire heating
elements!

5.9 DISMANTLING AND REASSEMBLING THE BELT
After carrying out the operations described in 5.1 above, to dismantle and
reassemble the belt proceed as follows:
- Remove the conveyor belt from the baking chamber by carrying out the
operations indicated in point 5.2.1, then place it on a worktop equipped with a long
nosed clamp.
5.9.1 DISMANTLING THE BELT
- After carrying out the operations described in 5.1 above, to dismantle the belt
proceed as follows:
- Slide the belt until the connector is at the centre top.
- Compress the right side of the belt (fig.22).
- Using the pliers, T75E T97E only: slide the four connector pipes sideways on the
links (fig. 23).
- Disconnect the mesh connectors using the clamp.
- Remove compression from the end of the belt.
- Pull the belt out
5.9.2 REASSEMBLING THE BELT
-After carrying out the operations described in 5.1 above, to reassemble the belt
proceed as follows:
- Insert the belt in the direction required, taking care that the top part is smooth and
that the hooked ends are never travelling in such a way that they will tend to hook
up (fig.27).
- Bring the ends of the belt together at the centre top, making sure that the toothed
wheels on the left hand end and the return bushes on the right hand end connect
properly to the belt.
NOTE for T75E and T97E only: The drive bushings must never be in
correspondence with the gasket pipes, the two wheels at the ends must be
turned as shown in the exploded drawing Tab.A.
- Compress the right side of the belt (fig.22).
T75E T97E: Take one of the side connection links and, after looking to see how
the ends of the belt are fitted (fig.24a), hook up first the outer side and then the
inner one, if necessary with the aid of a long nosed clamp.
- Repeat the above operation on the opposite side link.
- Hook up the intermediate pieces (fig.25), and with the aid of the clamp straighten
any links that may be bent.
- Insert the pipes onto the links, positioning them at the centre of the connector and
clamping them at the two ends (fig.26), making sure that they do not slide.
T64E-TT98E: Take one of the side connector links and after checking to see how
the ends of the belt are assembled (fig.24b), first hook up the outer side section and
then the inner one, using a long nosed clamp.
- Repeat the above operation on the opposite side link.
- Hook up the intermediate pieces and use a clamp to straighten any bent links.
- Check that the belt is lying flat, any bent sections of the belt must be straightened.
- Remove compression from the end of the belt.
- Check manually to ensure that the belt runs properly.
- Replace the conveyor belt in its housing inside the baking chamber and replace all
the other components as described in point 5.2.2
IMPORTANT! Make sure that the belt turns in the direction indicated in
fig.27, the hook-shaped ends must never move in a direction that will tend to
unfasten them, because this would not only damage the belt, but would also
render them extremely dangerous and liable to hook onto any loose clothing,
limbs, rings, bracelets etc.
IMPORTANT! To prevent the belt from squeaking, lubricate it with a thin
layer of spray oil exclusively of a type approved for use with food products,
which must be sprayed in the smallest possible amounts when the appliance is
turned off and cold, and only on the two parts of the belt that are outside the
cooking chamber, taking particular care to spray on the wheels at the two
ends of the belt.
When carrying out this operation particular attention must be paid to dangers
such as flammability, risk of explosion and the like, indicated on the spray
can.
5.9.3 REVERSING
MOVEMENT
- After carrying out the operations described in 5.1 above, to reverse the conveyor
belt direction of movement proceed as follows:
- Remove the conveyor belt from the baking chamber following the operations

point 5.9.1, turn the belt in the direction required and replace it following the
operations described in point 5.9.2.
T75E T97E: Open the electrical panel following the procedure described in point
