4.7 INTERVENTIONS PERFORMED EXCLUSIVELY
BY AUTHORISED TECHNICIANS
All maintenance interventions other than those described up to
this point must be considered extraordinary maintenance, and
must be carried out exclusively by authorized technicians, in
particular:
- replacement of blade support frames
- replacement or even only regulation of the spring of the control
lever
- replacement of the motor; in this case always check that the
direction of rotation is correct, as indicated by the arrow on the
drive pulley ref. 6 Photo E; if the direction of rotation is
incorrect, invert two phases inside the electrical plug; never for
any reason exchange the earth wire (yellow-green) with one
of the phase wires. When the machine is assembled it is
possible to check the direction of rotation by looking through
the slot on the left side of the bread loading surface, Figure 21.
4.8 POSSIBLE BREAKDOWN AND/OR ERROR SITUATIONS
We indicate here some error situations that could occur while the machine is in service.
The subsequent intervention must be carried out in compliance with the instructions, where provided,
and in any case only after having switched off and disconnected the machine from the electric
and pneumatic power supply.
Problem Possible causes Solutions
The machine
does not start
•
No electrical power
supply
• Protection fuses blown
• Safety device activated
- make sure the plug has been inserted properly in the
socket; if the light in the button ref. 1 Figure 5 is not lit
check the bulb, otherwise the problem lies upstream
from the machine
- check the safety devices for the electricity line in the
work place and reset them if necessary
- Check and replace them if necessary (par. 0)
- reset the emergency button
- microswitch associated with the control lever is faulty,
have it replaced (par. 0)
The machine
is very noisy
and vibrates
in an unusual
way
• Motor turning in the
wrong direction
- see par. 4.6
- th
e connecting rods of the frames as in Figure 17 Photo
M are worn, change them
The machine
working is not
uniform, the
bread
“jumps” up
and down
•
Belt tension not correct
• The spring of the comb
is not correctly
regulated
- Have it regulated or replaced (par. 4.4)
- Check the tension of the comb spring (par. 0)
Slicing quality
is not
acceptable
•
Blades worn
• Force exerted on the
bread by the pusher is
too weak or too strong
- Replace (par. 4.3)
- Adjust the return spring of the control lever (par.4.6)
