CARE AND MAINTENANCE
20. Electrical and elec-
tronic systems
Since even a test lamp can damage electronic
components in the electrical system, trouble
shooting must always be carried out in the work-
shop.
Disconnect battery if the tractor is not used for
long periods, to prevent it being discharged by
small consumers. Check the battery charge level
every 2 months. Do not operate the tractor wit-
hout a battery.
