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 belt from the side opposite the one with the motor shaft
(fig.22).
- Using the pliers, T64E T75E only: slide the 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 traveling in such a way that
they will tend to hook up (fig.27).
- Bring the ends of the belt together at the centre top, carefully checking
that the toothed wheels at the end with the
transmission wheels at the opposite end hook the belt correctly.
-
Compress the belt from the side opposite the one with the motor shaft
(fig.22).
NOTE:
The belt rollers must never be at the joints.
T64E T75E: 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.
TT96E 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
WARNING!
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.
WARNING!
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 baking 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 THE CONVEYOR BELT DIRECTION OF
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 described in point 5.2.1, dismantle the belt following the
operations described in point 5.9.1, turn the belt in the direction required
and replace it following the operations described in point 5.9.2.
T75E: Open the electrical panel following the procedure described in
point 5.3.1
- Reverse the two power cables on the gear motor, this will reverse the
direction of movement of the gear motor itself.
- Close the electrical panel following the procedure described in point
5.3.3.
- Remove the ARROW label indicating the direction of movement
(fig.4), and reapply it in the opposite direction.
motor shaft and the
UK/14
TT96E: see 3.2.11
Remove the ARROW label indicating the direction of movement
(fig.4d), and reapply it in the opposite direction.
TT98E: Open the side panel, loosening the 2 fastening screws (fig.16 part
L)
- Reverse the two power cables on the gear motor, this will reverse the
direction of movement of the gear motor itself.
- Remove the ARROW label indicating the direction of movement
(fig.16 part M) and in its place, attach the new label provided in the
instruction booklet.
- Position the blowers according to the indication of parts as shown
on the new label (fig 16 part.M) following the procedures in points 5.2.1
and 5.2.2.
- Close the side panel by tightening the 2 fastening screws (fig.16 part L).
T64E: Press for a few seconds in the control panel:
- Press "Up Arrow" to set the direction of movement CLOCKWISE
- Press "Down Arrow" to set to set the direction of movement
COUNTER CLOCKWISE
Remove the ARROW label indicating the direction of movement
(fig.4c), and reapply it in the opposite direction.
WARNING!
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 hook up, 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.
5.10 REPLACING THE TEMPERED GLASS (if any)
After carrying out the operations described in 5.1 above, to replace the
tempered glass proceed as follows:
- Open the front door (fig.15 part Q) and remove the four screws
fastening the inner panel.
- Remove the inner panel and replace the tempered glass.
- Carry out the steps in reverse order to reassemble.
5.11 REPLACING THE MOTOR OR BAKING FAN
After carrying out the operations described in 5.1 above, to replace the
motor or fan proceed as follows:
T64E T75E TT96E:
- Remove the rear panel (fig. 38 part T)
- TT96E only: remove the internal carter (fig. 38 part S), electrically
disconnect the fan, and remove the bracket with the fan by unscrewing the
3 fixing screws (fig. 38 part K-Z)
- Disconnect the motor and the thermal sensor fast-ons if present
- T64E and TT96E only: disconnect the terminals of the heating
elements using a second wrench on the locknut as an anti-rotation in
order to prevent forcing the terminal.
NOTE:
Forcing any of the heating element terminals during
connection / disconnection of electrical cables, irretrievably
jeopardizes the entire resistors!
- Remove the wool containment panels by unfastening the fixing screws.
-
Move the insulation and dismantle the rear baking chamber panel by
unfastening the fixing screws.
NOTE:
TT96E ONLY: BEFORE REMOVING THE FANS,
MAKE SURE YOU HAVE NOTED THE BLADES VERSE, IN
ORDER TO BE ABLE TO RESTORE THE INITIAL STATE.
- Take it to a worktop, straighten the plate preventing unscrewing (on
T75E only) and remove the left-handed screw at the centre of the baking
fan.
-
Remove the fan with the aid of an extractor.
NOTE:
The left-handed screw must be turned clockwise to
unfasten it; the fan will not come out of its housing unless an
extractor is used.
- Should it be necessary to replace the fan only, perform the above
operations in reverse order to reassemble.
- To dismantle the motor, remove the four nuts on the feet of the motor
and pull it out.
- Carry out the above operations in reverse order to reassemble, taking
great care that the gasket sliding on the drive shaft is properly
reassembled and does not force the rotation of the motor. Also make sure
that the conical parts of the drive shaft and fan are perfectly clean and
smooth.
NOTE:
Before startup, check that the engine rotates freely
otherwise it could be damaged.
