The fuse FU5 has blown.
The head descent actuator is disconnected or broken.
The poles and charging clips of the batteries are dirty and
oxydized.
The electrolyte level is low.
The battery-charger does not work or is unsuitable.
There are considerable differences in density between the
various elements of the battery.
The machine is working with a too high pressure on the brush.
The storage battery gets flat too fast during use, although it has been charged in the
correct way and when tested with a densimeter at the end of recharging, it turned out to be uniformly charged.
The storage battery is new and does not give 100% of its
expected capacity.
The machine is used at its maximum capacity for continuous
periods and the autonomy is not sufficient.
The electrolyte has evaporated and does not cover the plates
completely.
The storage battery gets flat too fast during use, the recharging with an electronic battery-charger is too fast and
at the end the storage battery gives the right voltage (about 2,14v for each empty element),
The storage battery, already filled with acid by the manufacturer,
has been stored for a too long time before being recharged and
used for the first time.
After recharging with an electronic battery-charger the storage-battery does not show the correct voltage (about
2,14v for each empty element) and only one or few elements turn out to be flat when tested with densimeter.
The storage battery has not been connected to the battery
charger.
The battery-charger and the power socket to which the storage
battery is connected are not compatible.

but it turns out to be not uniformly charged when tested with densimeter.

PROBLEM:
Check and remove the causes that made the fuse blow, then
replace it.
Have the connection restored or the actuator replaced.
PROBLEM:
Clean and grease the poles and clips, recharge the batteries.
Add distilled water topping up all elements according to the
instructions.
See instructions relative to the battery-charger.
Replace the damaged battery.
Reduce pressure on the brush.
PROBLEM:
It is necessary to "run-in" the storage battery by 20-30 charges
and discharges to obtain maximum performance.
Use, if possible, storage batteries with larger capacity or replace
the storage batteries with others already charged.
Add distilled water, topping up all elements until the plates are
covered and recharge the storage battery.
PROBLEM:
If the recharging with a normal storage-charger is not effective,
it is necessary to carry out a double recharging consisting in:
• A slow recharging of about 10 hours with a current equal
to 1/10 of the rated capacity expressed in 5 hours (ex.: for
a storage battery of 100Ah(5), the current should be 10A,
realized by a manual batterycharger);
• One-hour pause;
• Charging with a normal battery-charger.
PROBLEM:
Connect the battery-charger to the storage battery connector.
Check that the power supply characteristics indicated on the
battery-charger plate are compliant with those of the mains.
