The direction adjustment knob must be adjusted appropriately
for the floor.
The battery poles and charging terminals are dirty and oxidised. Clean and grease the poles and terminals, recharge the batteries.
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.
You are using the machine with excessive pressure on the
brushes.
There are considerable differences in density between the
various elements of the battery.
The battery discharges too fast during use, even though it has been charged correctly and when tested with a
hydrometer at the end of recharging, it turned out to be uniformly charged
The battery is new and does not deliver 100% of its expected
capacity.
The machine is being used atmaximum capacity for
continuous periods and the working time is not sufficient.
The electrolyte has evaporated and does not cover the plates
completely.
The battery discharges too fast during use, recharging with an electronic battery charger is too fast and after
recharging the battery supplies the right voltage (about 2.14v for each element without load), but when
The battery supplied filled with acid by the manufacturer has
been stored for too long before being recharged and used for
the first time.
At the end of charging with the electronic battery charger, the battery does not provide the correct
voltage (about 2.14 v per element without load) and appears to be uniformly not charged when tested
The battery has not been connected to the battery charger (for
example, because the low voltage connector of the battery
charger has been erroneously connected to the machine
connector).

PROBLEM:
Regulate the direction of movement by adjusting the speed
adjustment knob.
PROBLEM:
Top up all the elements with distilled water as described in the
instructions.
See battery charger instructions.
Replace the damaged battery.
Reduce pressure on the brush.
Replace the damaged battery.
PROBLEM:
The battery must be "run-in" by performing 20-30 charges and
discharges to obtain maximum performance.
If possible, use batteries with a higher capacity or replace
the batteries with others charged previously.
Top up all elements with distilled water until the plates are
covered then recharge the battery
PROBLEM:
If recharging with a normal battery charger is not effective, you
must use a double recharging cycle:
• Charge slowly over a 10 hour period at a current of 1/10 the
nominal capacity for 5 hours (e.g. for a 100Ah(5) battery the
current must be set at 10A, using a manual battery charger);
• Rest for one hour;
• Charge with the normal battery charger.
PROBLEM:
with a hydrometer
Connect the battery charger to the battery connector.
