when it intervenes, is NOT mounted on models SR 1100 and SR 5110; for
models SR 1200 and SR 5120 the temperature sensor has only been
mounted from serial number 003007445; on model SR 1300 it has
always been available: at first the temperature sensor was fixed on M M M M 5 5 5 5 drive
motor case with a pink chemical compound; starting from the machine
serial number 003708168 the sensor is fixed with a metal support and a
screw.

the appearance of code 3 3 3 3 0 0 0 0 1 1 1 1 could be normal in the following cases:
- The environment temperature is higher than 40°C / 104°F
- The machine worked on a slope for long period
- The machine is subjected to frequent speed or direction (forward /
reverse gear) changes
In any case let the machine cool off for at least 40 minutes before starting
to work again; in this way code 3 3 3 3 0 0 0 0 1 1 1 1 may disappear; if it doesn't, proceed with
the following inspections:
