Accumulator battery maintenance

Keep accumulator battery clean, well attached to the vehicle. The attachment device must not however
deform the accumulator vessel. The level of electrolyte must be under the minimum level (mark line) marked
on a vessel with polypropylene batteries.
Do the refill only with distilled water!
1. First study the instructions manual enclosed to the battery when working with accumulator!
2. When working with accumulator, protect your eyes with either goggles or a protective shield!
3. Electrolyte is an alkali, handle it therefore with due care! Rinse the skin stained with electrolyte
and neutralize with soap and water, just like the stained clothing. Keep away from children!
4. When recharging from electrolyte hydrogen is released on electrodes, which makes an explosive
mixture when mixed with air. It is therefore forbidden to manipulate with open fire near accumulator!
5. An explosion may be caused by a spark incurring after disconnection or release of clamp with
engaged charging circuit!
6. Discarded accumulator is environmentally hazardous waste - when buying a new accumulator,
hand the old one over to a seller who will dispose of it free of charge.
7. Insufficiently charged battery can freeze in winter!

Alternator

It is accessible after hinging the bonnet away. Charging
check is indicated by a red control on the compound
dashboard device, which must go out after starting.
When repairing tractor by electric welding, all
the conductors must be disconnected alternator.
Protect conductor '+B' against short circuit.

Alternator maintenance

When washing and cleaning tractor protect alternator prior to penetration of water or oil!
You must not disconnect alternator from accumulator during operation!
Alternator must not ever be put in operation with a disconnected conductor from of clamp '+B' and
connected clamp '+D'. Such condition when increasing the revolutions may cause an exceptionally
high alternator voltage which would damage semiconductors!
Never short circuit any clamp of alternator in operation!
Alternator must not be over activated. There is a risk of semiconductors damage with this
intervention!
Mind the perfect electrical joint on connecting clamps and on perfect alternator grounding!
Alternator must not be overpoled not even for a short time!
