Electrical system - Warnings
Itisabsolutelyforbiddentomakechangesorconnections
to the data interconnecting lines between control
units (CAN-BUS lines). They are to be considered as
INVIOLABLE.Alldiagnosticandmaintenanceoperations
mayonlybecarriedoutbyauthorizedtechnicians,with
specificappliancesapprovedbyLandini.
Useonlyfuseswiththeratedcapacityfortheirspecific
function.Donoteverusefuseswithhigherratedcapacity.
Replaceablown fuse only after correcting the relative
malfunction and turn off any keys and users before
replacing.
Please keep in mind that electrical systems made by
unqualifiedpersonsmightseverelydamagethesystems
on board the tractor (control units, harnesses, sensors
etc.),andjeopardizetheridingsafetyandgoodoperation
of the tractor. Such damages ARE NOT COVERED BY
OURCONTRACTWARRANTY.
Never disconnect control unit and sensor connectors
while the engine is running and the control units are
powered.
Negative conductors connected to a grounding point
of the system must be as short as possible and star
connectedwitheachother.
Asaprinciple,thegroundingconnectionsofthetractor
maynotbechanged.
If the creation of further grounding points is required,
theholesalreadyprovidedontheframemustbeused,
takingcareofthefollowing
-removelacquerfromtheframe
-useasuitablehighlyconductivelacquerbetweenframe
andcableterminal
- connect the ground within 5 minutes from lacquer
application
THE POINTS PROVIDED FOR ENGINE CONNECTION
TO GROUND MUST BE ABSOLUTELY AVOIDED FOR

Starter motor
The starter motor should be thoroughly cleaned after
periodsof1000 hours or atleastonce a year.Parti-
cularlychecktheconditionofthebrushesandcollector.
Alternator
Thealternatorkeepsthebatteryfullycharged.
The alternator is a brushless model and requires no
specialmaintenance.However,thefollowingprecautions
mustbeobserved.
1- Whenfittingabattery,makesurethatthepositive
andnegativeterminalsareconnectedtothesame
leadsasthealternator.Ifthebatteryterminalsare
inverted,youwillshortcircuitthebatterythrough
thealternatordiodes.
2- Whenconnectingthebatterytoacharger,make
surethatthepositive(+)leadofthechargeris
connectedtothepositiveofthebatteryandthe
negative(-)tothenegative.Incorrectconnection
willdamagethediodesandtheothercircuit
components.
3- Neverrunthealternatorunlessitisproperly
connected.
Ifthebatteryisnotconnected,highvoltagescan
buildupinsidethealternatorthatcanbeextremely
dangerousiftheoutputterminalistouched.
Makesurethatallconnectionsarefirmandtight
beforecarryingoutanyinspectionsortestsonthe
electricalsystem.
4- Nevershortcircuitorearthanyofthealternator
terminals.Thiscoulddamagetheelectricalsystem.
5- Neverinvertthealternatorconnections.Thebattery
andalternatorearthsmustbeofthesamesignor
thealternatordiodeswillbedamaged.
6- Alwaysdisconnectbothalternatorterminalsbefore
undertakinganyelectricarcweldingonthetractor.
WARNING: Always use specific personal safety devices
for each operation.
