1.8. MAINTENANCE

 Squeezer Machine: Grease the roof hinge occasionally. (Fig. 34). (Thick grease –
consistency grade 2 DIN 51818 and distilled water grade 0 corrosion resistance).
 Glass conveyor: Grease the guides (Fig. 35 and 36) (water repellent grease).
Attention! Do not use aerosol lubricants, as these would grease the belt, causing it
to slip.
 Cooling Unit: Clean the ventilation grilles (Fig. 42).
Loader: Grease the upper and lower bearings. (Thick grease –consistency grade 2 DIN

51818 and distilled water grade 0 corrosion resistance).

1.9. TROUBLESHOOTING

 GLASS CONVEYOR: (Fig. 32, 35, 36).
- Check that the drive pulley does not slip on its axis. Should this be the case, tighten the
fastening stud on the pulley.
- Check that the belt does not slip on the drive pulley. Should this be the case, tighten the belt
or apply a non-slip product.
- Check that the photocell led turns on and off when the glass is placed in front of it. Where
necessary, clean the lens (Fig. 39).
- If glasses are on the lower stool, probably is because they have an oval shape. Please
store the glasses so that they are not misshapen.
 CUP DISPENSER (Fig. 19).
- If the "No Glasses" signal appears when there are glasses, It means that the Cup Dispenser
tried three times to dispense a glass but none have fallen. Check that the glasses are not
overly stuck together or misshapen.
 LOADER AND ROLLER CONVEYOR: (Scheme 1, No. 14 and 13)
- If the loader does not start, despite there being no oranges on the rollers, check that the
rollers photocell led turns on and off by bringing your hand towards it. Where necessary,
clean the photocell lens (Fig. 40).
- Check that the left end of each roller is in its correct position (Fig. 28). If the rollers have
come out of their housing then the orange tank may be too full (Fig. 18).
 COOLING SYSTEM:
- If there is condensation inside the machine, this implies it is colder outside the machine than
in. This is because the thermostat is adjusted to a temperature that is too high. In winter, the
temperature should be lowered to avoid this. It may also be that the ventilation grilles are
obstructed. Pull the machine away from the wall.
- Remove the ventilation grilles and check: a) the compressor unit ventilator that must always
be working when the compressor is working (Fig. 41). b) That the condenser air inlet is not
dirty (Fig. 42).
 SELF-CLEANING SYSTEM:
- Check that the water suction pipe is pushed to the bottom (Scheme 1, No. 3).
- Check that the Water Level Sensor is in position and that works correctly (Fig. 10).
- Check that the water pump are working by pressing button S3 (Scheme 2). (Remember to
place the door switch at "free"). (Sect. 6, point F)
- If the water pump is being used and when button S3 is pressed a characteristic noise is
heard but the water does not reach the nozzles, dismantle the water pump and clean the
rubber membrane, which is bound to contain a small stone of some kind.
 COIN OPERATOR:
- Check that field 6 is programmed for the type of Coin Operator installed.
