Maintenance
After each washing operation, all accessible washers should be greased with vaseline to ensure ease
of assembly and operation.
Check the washers and springs on the pump unit each week and if necessary replace them. This is
extremely important for trouble-free operation of the machine.
Check periodically that there
is not too much play (
3
) between
the eccentric shaft (
1
) and
bushing (
2
).
The play (
3
) must be maximum
1 mm
. If it is more, replace piece
(
4
) complete with bushing.
If there is excessive play, scraping
of the ice-cream will not be carried out
correctly and the knives will wear
out rapidly.
After the first month of operation:
- Check the tension of the turbine stirrer
motor belts. Even if just one is worn,
change them all.
After each season of operation check
the following:
- The worm screw reduction unit (
3
) is
oil lubricated. Check the level and top
up as necessary.
After
4000 hours’
operation change the oil.
The types of oil are as follows:
IP TELESIA OIL 15° OR
BP ENERGOL SGXP 150
Quantity =
1 kg.
- Check lubrication of the connecting rod (
4
).
Lubricate with grease and if necessary
add
SKF LGMT 2/1
.
- Check the lubrication of the support which
pulls the turbine. The same grease should be
used for this purpose as mentioned above.
At the start of each season, check the
condition of the refrigeration plant:
- Check the refrigerating gas
- Clean the condenser
