Discharging
The vent apertures in the
machine must not be closed or
covered.
Opening or closing of electrical
connections (e.g. plugs,
connection leads) may take
place only in the currentless
state with the mains switch
switched off.
In order to reach an optimum
service life, discharges are
permissible only up to the point
at which a certain residual
capacity is reached.
In order to avoid total
discharges, the controls of the
machine contain an automatic
switch-off device which
switches off the main consumer
in good time when the cut-off
voltage is reached and signals
this by means of a red warning
lamp.
Discharged batteries are to be
charged immediately and must
not be left in the discharged
state. This also applies after
partial discharging.
Charging
WARNING!
Only used chargers approved
by Alto for charging.
Maintenance
Maintenance-free, sealed
batteries
Wet batteries
Daily
•
Charge battery after every discharge.
Weekly
•
Visual inspection for dirt and mechanical damage.
•
Grease terminals with terminal grease (Vaseline) and check to
ensure firm fit.
In the case of wet batteries, the
water consumption is influenced
by the operating conditions and
the charging set used.
The water level should not fall
below the minimum mark (top
edge of separator). If necessary,
top-up with distilled water again
after charging.
In the case of maintenance-free
batteries, no topping up with
water is required for the entire
service life.
Care
The battery is to be kept clean
and dry at all times in order to
avoid leak currents and
sparking.
For cleaning, remove batteries,
wear protective goggles and
protective clothing.
Select the place of installation
so that dirty rinsing water
produced during cleaning is
channelled to a suitable waste
water treatment plant.
The cell plugs must not be
unscrewed.
The plastic parts of the batteries
may only be cleaned with water
or cleaning cloths soaked in
water without additives. After
cleaning, the surface of the
battery is to be dried
(compressed air, cleaning
cloths).
