Maintenance and Care

5.4.1 Charging Batteries

Use the integrated battery charger
(Fig. 7/3) to charge batteries. Connect 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. Observe the operating
instructions of the charger 88-60-2723 as
well as the operating instructions of the
battery manufacturer. If the battery type is
changed (ex. from lead acid to gel) the
charger has to be adjusted by a Minuteman
contract workshop.

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.

5.4.3 Maintenance of Drive Batteries

Refer to operating instructions 88-60-2556
for information on care of drive batteries.

5.4.4 Removing Batteries

1

Park machine on level ground.

2 Switch off machine by key switch.
3 Open empty recovery tank (Fig. 7/7) and

secure by support (Fig. 7/8).

4 Disconnect battery connector (Fig. 7/ 5).
5 Disconnect battery connection cables.
6 Remove batteries.

5.4.5 Installing Batteries

Due to alteration of the center of
gravity , only use batteries as released
and at the prescribed position.

1 Switch off machine by key switch.
2 Open empty recovery tank (Fig. 7/7) and

secure by support (Fig. 7/8).
3 Place batteries according to figure.
4 Connect battery poles and enclosed con-

necting cables according to wiring diagram

(Fig. 7/9). Tighten fasteners and grease

poles.

5.4.6 Disposal of Batteries

Used batteries labelled by the recycling
symbol contain re-usable substances. Such
batteries must not be added to normal
household waste. Obtain local information
for the proper disposal of used batteries.

coupling (Fig. 8/6) is available. Before doing
so, connect the filling hose of the dosage
unit and the quick coupling. The floater valve
automatically closes after the maximum
filling level has been attained.
(Refer to specific operating instructions for
information on operation of the dosage unit)
The maximum admissible service pressure
of the floater unit is 87psi.

5.5.2 Emptying Solution Tank

Park machine such that the fill level hose
(Fig. 8/3) is located above the drain aperture
in the floor. Take fill level hose from holder
and remove lid.

5.5.3 Solution Filter

Check solution filter (Fig. 8/4) at weekly
intervals and clean or replace if required.

graph 5.5.2.
2 Unscrew filter cap.
3 Remove the filter element from the filter

case for cleaning. Replace if required.

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 rollers and floor
must be adjusted by changing the number
of washers on the holder.

Maintenance and Care

3 mm

In the case 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 the case 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.

The Squeegee is equipped with
two additional rollers which are
adjusted at the factory to a
distance of 10 mm to the floor by
means of spacers.
