The valves should open at a pressure as specified in
the chapter Technical specifications.
If the valves open too soon: remove a washer, if
installed, between valve seat (4) and housing (1) or
add a washer between spring (2) and housing.
If the valves open too late: remove a washer, if
installed, between spring and housing or add a washer
between valve seat and housing.

The battery must be in operation within 2 months
from being activated; if not, it needs to be recharged
first.

Electrolyte in batteries is a sulphuric acid solution in
distilled water.
The solution must be made up before being
introduced into the battery.

the level marked on the battery.
