Servicing and maintenance works Electrical system

Regulations for working on the electrical system

Battery

Do not touch the voltage conducting parts,

faulty warning lamps should be immediate-

ly replaced.

Pay attention to correct polarity of the con-

nections.

Cover electrical/electronic parts and con-

nections to clean the engine (e.g. control

units, generator, solenoid valves etc.). Do

not aim the water/steam jet directly at them.

Allow engine to warm up.

Touching a lead against the frame to check

whether it is live must not, under any cir-

cumstances, be carried out.

For electrical welding work, the ground ter-

minal of the welding gear must be clamped

directly to the part being welded.

Three-phase current generator: Never dis-

connect the cables between battery, gener-

ator and regulator while the engine is

running.

Electronically stored data could be lost if

the battery is disconnected.

Keep battery clean and dry.

Make sure the battery is fitted correctly and

securely.

Dispose of old batteries in an environmen-

tally friendly way.

Checking the voltage

Check the battery voltage with a conventional

voltmeter. The voltage indicates the charging

state. It should be between 12 and 14.4 Volt de-

pending per battery.

Check acid level

Unscrew caps.

Note the manufacturer’s specifications concern-

ing the liquid level.

The liquid should normally be 10-15 mm above

the top edge of the plate or reach up to any avail-

able control device.

Only use distilled water to top up the battery.

Screw in caps.

Danger of explosion! The gases emitted by

the battery are explosive!

Fire, sparks, smoking and naked lights are

prohibited!

Danger of acid burns! Wear protective

gloves and glasses! Avoid contact with skin

and clothing!

Danger of short circuit! Do not rest tools on

the battery!

Check acid density

Unscrew caps.

Measure the electrolyte density of individual cells

with a commercial hydrometer. Hydrometer

reading indicates battery’s state of charge. The

acid temperature when measuring should be 20

°C if possible.

Check the acid level before recharging.
