BATTERY
The machine operates with a 36 Volt battery.
Three options are available, depending on the country where the machine is supplied:
1-Battery supplied together with the machine and fitted, filled with acid and ready for use.
2-Battery supplied and fitted dry (i.e. without liquid electrolyte).
3-Battery not supplied.
DANGER!
During installation or any type of maintenance of the batteries, the operator must be equipped with
the necessary accessories (gloves, goggles, protective overalls etc.); to limit the risk of accidents,
keep away from naked flames, do not short-circuit the battery poles, do not generate sparks and do
not smoke.
The batteries are normally supplied filled with acid and ready for use. If the batteries are without
acid, before fitting them on board they must be activated as follows:
- after removing the battery plugs, fill all the elements with sulphuric acid solution (density from
1.27 to 1.29 Kg at 25°C) making sure that the plates are fully covered;
- leave to rest for 4-5 hours, to give the air bubbles time to come to the surface and the plates time
to absorb the electrolyte;
-check that the level of the liquid is still above the plates; if not, top up the level with the sulphuric
acid solution;
-re-close the plugs.
A first recharge should now be performed before operating the machine: for this operation follow
the directions in the relevant paragraph.
BATTERIES: installation and connection
Make sure that you fit only terminals marked with the symbol “+” on the positive poles. Do not
check the battery charge by sparking. Carefully follow the instructions below as short-circuiting of
the batteries can cause them to explode.
Fit the batteries on the machine using equipment suitable for their weight. The positive and negative
poles have a different diameter. Referring to the arrangement of the cables schematised in the
drawing on the battery case, connect the terminals to the battery poles.
Having arranged the cables as shown in the drawing, tighten the terminal fixing bolts using a
spanner of suitable diameter and cover the poles with Vaseline; connect the battery wiring
connector and the machine wiring connector together:
use the machine according to the instructions below.
THE BATTERY CHARGER
Never let the batteries become too low as they can be permanently damaged.
Choice of battery charger:
check that the battery charger is compatible with the batteries to be charged:
-
tubular lead batteries: the battery charger must have a maximum initial current of 16 A (with
DIN Wa method) or 20 A to 50 A (with DIN Wo Wa two-stage method) for every 100 Ah
(5h) of the battery. Consult the manufacturer and the battery charger manual for
confirmation of the choice.
-
Gel batteries: use a battery charger specific for this type of battery.
