Maintenance and Care
5.4.1 Charge Batteries
Use the integrated battery charger (Fig.
7/3) to charge batteries. Proceed to
connection of the charger by means of
the mains cable (Fig. 7/4) with safety
plug. Charging batteries is recommended if at least one bar of the LDS display has extinguished after operation of
the machine. On this behalf you are requested to observe the operating instructions of the charger 88-60-2723 as
well as the operating instructions of the
battery manufacturer. In case it is intended to change the type of battery the
charger has to be adjusted only by Minuteman contract workshops.
Charge the batteries properly
before starting the machine for
the first time. Minuteman
cannot be held liable for battery damage resulting from failure to initially charge batteries.
Provide for sufficient ventilation of areas where batteries are
charged. – Explosion hazard!
5.4.2 Low Discharge Signal sender
(LDS)
The machine has been equipped with a
charge indicator to preclude the batteries from low discharge. This low discharge signal sender has been
integrated into the electronics. If other
batteries are used, readjustment of the
low discharge signal sender is required.
Only Minuteman contract
workshops are authorized to
adjust the low discharge signal
sender.

and secure by support (Fig. 7/8).
4. Disconnect battery connector (Fig. 7/
5).
5. Disconnect battery connection ca-
bles.
6. Remove batteries.
5.4.5 Install Batteries
Due to alteration of the center
of gravity, only use batteries as
released and at the prescribed
position only.

Maintenance and Care
5.9.3 Adjusting the Blades
Angle Adjustment
The angle adjustment is the decisive
factor in ensuring that the squeegee
blades on the squeegee lie evenly on
the floor.
1. Park the machine on a level surface
and lower the squeegee.
2. Loosen the counternut on the adjusting screw (Fig. 12/3) and adjust the
squeegee using the adjusting screw
so that the ends of the squeegee blades have contact with the floor.
Figure A
Turn the adjusting screw counterclockwise: The clearance between
squeegee blade and floor is reduced
in the center.
Figure B
Turn the screw clockwise: The clearance between squeegee blade and
floor is increased in the center.
3. Switch the machine on and check
the suction pattern. When the machine is operating, the entire surface of
the squeegee blades (center and outer areas) must be applied as evenly
as possible.
4. Tighten the counternut on the adjusting screw at 5 lb ft.

Maintenance and Care
Height Adjustment
The height adjustment is set to 3 mm at
the factory. If streaks are produced, despite an optimum angle adjustment, the
clearance between the casters and
floor must be adjusted by changing the
number of washers on the holder.
In cases of very smooth floors, e.g. finished floors, PVC, linoleum, etc.
Number of washers = 2. This corresponds to a clearance of approx. 2 mm.
In cases of very uneven floors, e.g.
poorly laid tiles (water does not run off)
Number of washers = 4. This corresponds to a clearance of approx. 4 mm.
