BATTERYBattery is located behind the front maskof bonnet and is accessible after re-moving the side shields.∗∗∗∗ Battery switch is located on the righthand side of engine compartment (seepicture S22).

If the tractor is out of operation forlonger period of time, it isnecessary to charge the battery atleast once in three month becauseof the battery selfdischarging andthe spacing current of AEV warninglights breaker. It is recommendedto disconnect the battery by meansof the battery disconnecting switchin case the tractor is put out ofaction.

BATTERY MAINTENANCEMaintain the battery clean, good fixed to the vehicle. The fixing device mustn’tdeform the battery case. Electrolyte level mustn’t be under the minimum mark that ison the case.

Add distilled water only!1. First study the operator’s manual before working with batterry!2. Safe your eyes by glasses or by safety shield!3. Electrolyte is a caustic agent that’s why keep attention when working

with electrolyte! Neutralize the skin and wear stained by electrolyte withsoap water. Wash them by clean water.

4. Hydrogen is released from electrolyte at charging the battery and thiscreates the explosive mixture being mixed with the air! That’s whymanipulation with open flame and smoking at battery is forbidden!

5. The explosion might be caused by a spark created at manipulation withbattery terminals when the closed charging circuit!

6. Keep children out of battery and electrolyte!7. Discarded battery is ecologically dangerous reject! Let it scrap by

specialists (service network). They will do it free of charge when buyingthe new battery.

ELECTRICAL INSTALLATIONCHARGING AND MAINTAINING THEBATERYA) Charging on the vehicle and out-

side the vehicle1. Systematic overcharging and dis-

charging of battery damages andshortens its life. Correctly adjustedcharging system maintains batterynear to the fully charged status. At setlevel of voltage (13,8 - 14,4 V) incharging system and average tractoroperation it is sufficient to check andmaintain the level of electrolyte bydistilled water once per six month.

2. At heavier operation and another levelof regulated voltage it is necessarymore frequent checking the level ofelectrolyte. Overcharging the batteryon vehicle (more than 14,4 V) causesbigger loose of electrolyte.

3. It is necessary to charge the batteryremoved from the vehicle or in thevehicle which is not in operation (seestorage of charged batteries withelectrolyte). It is also suitable tocharge battery in vehicle beforewintertime and after wintertime. Inwinter season and strong frost theelectrolyte might be frozen at almostdischarged battery (density ofelectrolyte 1,12 - 1,15 g/cm3) in thiscase the life will be substantiallyreduced (disintegration of active

agent and destroy of battery case).Heavily discharged battery (density ofelectrolyte lower than 1,07 g/cm3)might be frozen already at severaldegrees below zero.

4. Charge the battery by current that is0,1 of total battery capacity (or lower)up to fully charged status.

5. Charging device with constant voltage14,4 V can be also used. Chargingtime can be max. 30 hours accordingto status of discharging.

6. Fully discharged battery must becharged as soon as possible, other-wise its full capacity can not be re-stored.

B) Charged battery1. Battery is considered as fully charged

if all battery cells generates the gaswith same intensity. If the electrolytedensity is 1,28 g/cm3 in all cells and ifthe total voltage of battery is within15,3 - 16,5 V, measured with theprescribed charging current.

2. Status of full charging is confirmedwhen the received density of electro-lyte and level of voltage is notchanged within farther two measure-ments following after two hours.

3. For example the charging status foryour orientation: status of chargingcorresponds to density of electrolyte.Charging status is characterized by

density of electrolyte and is measuredby densimeter. Every cell needs to bemeasured.Status of charging = density of electrolytecharging status electrolyte density

100 % 1,28 g/cm3

70 % 1,23 g/cm3

50 % 1,20 g/cm3

20 % 1,15 g/cm3

0 % 1,12 g/cm3

C) Storage of charged battery withelectrolyte

1. Before storage the battery must becharged up to final symptoms ofcharging. It must be disconnectedfrom charging system, cleaned andwith plugs.

2. Battery that is built into a plastic casefrom polypropylene must be chargedafter three month of storage becauseof smaller self-discharging.

3. Intervals for checking the status ofelectrolyte are: when charging thebattery or minimally once per 6month, battery is maintained byadding the distilled water! If someelectrical components are per-manently connected even at discon-nected key switch (for exampleWarning) it is necessary to check thestatus of charging - i.e. voltage w/oload and electrolyte density min. 1xafter 1 month.

ALTERNATORAlternator is located on the right handside of engine. Charging status isindicated by red indicator light on thegauge display.

Damaged indicator light bulb12 V 2 W must be immediatelyexchanged. If the indicator lightbulb is damaged the battery isn’tcharged!All wires connected with thealternator must be disconnectedwhen repairing tractor by electricarc welding. Protect the wire"+B" against short circuit.

ALTERNATOR MAINTENANCE- Protect the alternator against penetration of water or diesel fuel when washing and

cleaning tractor.- Battery must never be disconnected at operation!- The alternator must never run without load i.e. with disconnected terminal "+B"

and connected terminal "+D". This status creates excessively high voltage ofalternator at increased engine speed and this voltage damages the alternatorelectronics.

- Never create the short circuit of any alternator connector at operation.- Alternator must not be additionally excited. Alternator electronics is damaged in

this case.- Keep the perfect electrical connection of alternator terminals and perfect alternator

ground.
