- Wipe off overflowed fuel.

- Do not smoke when working on the fuel system and do not use naked light! There is a danger of fire!

SAFETY INSTRUCTION FOR WORK ON ELECTRICAL WIRING • Disconnect the battery when carrying out any repair in the charging circuit to avoid incidental short-circuits.

• When dismantling, first disconnect the cable from the negative pole (-), then from the positive one (+).

• Do not disconnect batteries when the engine is running!

• Connect the “minus“ pole of the battery to the chassis and the “plus“ pole to lead “B+“ from the alternator. In case of the reverse connection the whole semiconductor device could get destroyed.

• When starting with auxiliary external supply, do not disconnect such supply sooner than the battery of the machine is connected. Watch out starting voltage of the auxiliary external supply (for 24 V).

• Do not put the alternator into no-load run, i. e. with the wire disconnected from the “+“ terminal and connected “D+“ terminal.

• Do not check the presence of voltage in the wire by sparking it on the chassis of the equipment.

• Do not do anything that produces sparks.

• When handling batteries, use protective rubber gloves and goggles.

• Protect your skin and clothes from stains by electrolyte or lead particles.

• When electrolyte gets into your eye, rinse it with a stream of water for a few minutes. Then see a doctor as soon as possible.

• When electrolyte stains your skin or clothes, take off your clothes, wash the stained area with soap water or with a solution of baking soda and water and see a doctor.

• After taking electrolyte incidentally, drink as much milk or water as possible or a solution of magnesia and immediately see a doctor.

• Never pour distilled water into the cells unless the operation of the machine or charging outside the equipment follows.

In such case the battery would self discharge increasingly.

• Never add sulfuric acid (H2SO 4)!

• Do not overturn the batteries because electrolyte could run out of the degassing holes of the battery.

• If acid (electrolyte) is spilled, rinse the place with water and neutralize it with lime.

Batteries

13. ELECTRICAL WIRING

Two batteries 12 D HD 135 are connected in series and located to the rear of the frame.

Handling Fill cells with sulfuric acid of specific density 1.28 g/cu. cm, 5-10 mm above the plates. Equalize the electrolyte and the battery to 15 – 20 °C when filling.

Let the electrolyte soak in the plates for 20 minutes, in batteries older than 6 months for 3 hours. Top possible level drop to 5 – 10 mm above plates. Charge the battery according to table.

The highest charging temperature is 40 °C. If necessary, cool by air flow or water bath, or lower charging current, or charge intermittently.

Currents lower than those indicated in the table are beneficial, however, charging will be prolonged. Leave input openings uncovered. Check the level and density of the electrolyte when finished charging. If necessary, top the level and adjust density to 1.28 g/ cu.cm. Tighten the plugs after 2 hours of degassing, flush the outside of the battery with water and clean dry.

Charging current table - example Type

Capacity

The values are correct for electrolyte temperature of 27 degrees C. At temperature lowers by 15 degrees C the electrolyte density is higher by 0.01 g/cu.cm. When topping up the electrolyte, density readings are correct after 10 to 30 minutes of charging, depending on the current and the intensity of bubbling. The level may be raised before charging up, to 5 to 10 mm above cell dividers.

Maintenance during operation Correctly working charging circuit maintains the battery close to full charge. The level of regulated voltage is between 27.6 and 28.4 V. When the voltage level is adjusted to these values, the electrolyte level is checked every 3 months. In summertime, check once a week. Battery overcharging is indicated by the electrolyte volume decrease. Insufficient charge affects the density of the electrolyte. Idle battery discharge is 1% of the capacity per day.

Battery is charged by current 0,1 overall capacity until fully charged.

The batteries must be kept clean, properly fastened, the holder must not deform the battery block.

Vaporization of the electrolyte forms a layer of sulfites on the surface of metal pieces, which must be cleaned.

Cleaned surfaces are to be protected by a light layer of Vaseline or oil.

Idle batteries must be charged up after two months.

Safety rules Indication of completed charging Battery is considered fully charged when all cells bubble intensively and the electrolyte indicates density of 1.28 g/cu.cm. The terminals read 15 to 16 V. Full charge is checked after further two hours; values shouldn‘t vary from initial readings. Battery is discharged when density drops to 1.12 g/cu.cm.

Instantaneous charge rate is indicated in the following table:

While handling full batteries one must be very careful. Use gloves and goggles.

Stained skin must be washed and neutralized by soap and soda. During charging the electrolyte develops oxygen and hydrogen, an explosive mixture. It is not allowed to handle open flame near charging batteries. An explosion may occur if caused by a spark resulting from disconnecting or loosening the clamp while the charging current is present.

When removing the battery, disconnect minus cable first.

It is not allowed to disconnect the battery while the engine is running.
