Electric drive version (BT): on the back of the control panel, move the bridge (fig. 17) to
select the type of battery installed on the machine (ACID-LEAD/GEL)
CT90-MICRO SCRUB version: set the machine software to the type of battery installed,
following this sequence:
1. turn the machine on by turning the key switch (fig. 6, ref. 15), wait 5 seconds and
make sure the display comes on.
2. press the brush buttons (fig. 6, ref. 3) and suction button (fig. 6, ref. 2) together for
at least 5 seconds. This accesses the battery setting menu.
3. press the suction button (fig. 6, ref. 2) to select the type of battery installed on the
machine "ACd" for acid batteries (tubular leak-proof batteries) or "GEL" (GEL
batteries).
4. memorise the displayed parameter by pressing the emergency button (fig. 6 ref.
15).
5.5.1. Batteries: preparation
!
DANGER
While installing or performing maintenance on the batteries, the operator must be
provided with the necessary personal protection devices (gloves, goggles, overalls,
etc) to limit the risk of accident. Keep away from naked flames, avoid short
circuiting the battery poles, avoid sparks and do not smoke.
The batteries are normally supplied filled with acid and ready for use.
If the batteries are dry, before mounting them on the machine, proceed as follows:
•
remove the caps and fill all elements with specific sulphuric acid solution until the
plates are entirely covered (this requires at least a couple of passes for each element);
•
leave for 4-5 hours to allow the air bubbles to come to the surface and the plates
to absorb the electrolyte;
•
make sure the level of electrolyte is still above the plates and if necessary top up
with sulphuric acid solution;
•
close the caps;
•
mount the batteries on the machine (following the procedure described below).
Before starting up the machine for the first time, charge the batteries. Follow the
instructions in the relevant section.
5.5.2. Batteries: installation and connection
!
DANGER
Check that all switches on the control panel are in the "0" (off) position.
Make sure you connect the terminals marked with a "+" to the positive poles of the
battery. Do not check the battery charge by sparking.
Follow the instructions given below meticulously as short circuiting the batteries
could cause them to explode.
1. Make sure the two tanks are empty (if necessary, empty them. See the relevant
paragraph).
2. Release the dirty water drum (fig. 2, ref. 2) from the detergent tank (fig. 2, ref. 7)
by pulling the catch (fig. 4, ref. 1).
3. Lift the dirty water drum and tilt it backwards by about 90°. This provides access to
the battery compartment (in the detergent tank) from above.
4. Place the batteries in the compartment in the direction shown in the drawing
printed inside the compartment on the detergent tank.
