Maintenance
Teat preparation
Check that the vacuum is turned on
immediately before attachment by listening
to the change in sound from the cup. To
maintain good udder health, check that teat
cleaning is carried out without water
escaping from the top or at the holes on the
sides of the cup. If this occurs, the tube
might be damaged or the teat is too long.
Maximum teat length is 70 mm. Make sure
that the wastewater and foremilk from the
teat preparation are drained from the
wastewater tank when the teat cleaning is
completed. Also check the teat cleaning
sealings concerning wear and leakage.
Function of disinfect spray
To maintain good udder health, check that
all teats are disinfected properly. Refill
disinfect liquid if necessary. (The liquid is
kept in the front section of the milking
station.)
Movements of the magazine between
milking and cleaning/backflush position
To avoid stop alarms, check that the
movements appear normal.
Backflush: Interior rinsing of teatcups
and teat preparation cup
To prevent stop alarm as well as
contamination between cows, confirm that
the lid covers the teat preparation cup
during the backflush.
Cup shower (exterior rinsing of the
teatcups)
Check that the teatcups are rinsed on both
sides.
Liners and milk tubes
To maintain good udder health, check that
the liners and milk tubes are free from
puncture and other damage.
