Checking the battery condition,
acid level and acid density
WARNING
The electrolyte (dilute sulphuric acid) is
poisonous and caustic!
–
Observe safety regulations for han-
dling battery acid; see chapter "Bat-
tery acid".
–
Wear personal protective equipment
(rubber gloves, apron and protection
goggles).

Rinse away spilt battery acid immedi-
ately with plenty of water!
CAUTION
Risk of damage!
–
Heed the information in the operating instructions
for the battery.
–
Remove the battery from the truck.
–
Inspect battery for cracked housing, raised
plate sand acid leaks.
–
Have defective batteries repaired by the au-
thorised service centre.
–
Open filler cap (1) and check the acid level.
For batteries with "caged cell plugs", the liquid
must reach the bottom of the cage.
For batteries without "caged cell plugs", the
liquid must reach a height of approx. 10 to 15
mm above the lead plates.
–
Top up missing fluid with distilled water on-
ly.
–
Clean the battery cell cover and dry if nec-
essary.
–
Remove any oxidation residues on the
battery terminals and then apply acid-free
grease to the terminals.
–
Tighten the battery-terminal clips (2) to a
torque of 22–25 Nm (depending on the size
of the terminal screws used).
–
Check acid density with an acid siphon.
After charging, the acid density must be be-
tween 1.28 and 1.30 kg/l.
