3.1 Method of Operation
General

The E33XL is a vacuum scrubbing ma­chine for wet cleaning of hard-surfaced
floors.

3.1.1 Brush Head

Lower brush head (Fig. 3/1) via pedal
before scrubbing. The brushes rotate
and solution supply switches on auto­matically. When the machines stopped,
brushes and solution supply switch off
automatically.

3.1.2 Solution Tank

Fill the solution tank (Fig. 3/2) after re­moving the cover. The solution tank
holds 29.8 gallons and the filling level
can be checked visually (through trans­parent hose). Regulation of solution
amount is available via adjustment
handle.

Operation

3.1.3 Squeegee

The movable squeegee (Fig. 3/3) con­sists of the squeegee lift-out, the suc­tion turbine and sealing strips. The
soiled water is wiped from the floor by
means of sealing strips. Squeegee is lo­wered via hand lever. Simultaneously,
the suction turbine switches on. The
suction turbine works independent of di­rection of travel and even if the machine
stops. Second actuation of the hand le­ver lifts the squeegee up again and suc­tion turbine is automatically switched off
with a delay of 15 seconds.

3.1.4 Recovery Tank

The soiled water is taken from squee­gee to the recovery tank (Fig. 3/4) by
suction turbine and suction hose.

3.1.5 Travel Drive

The machine features a continuous tra­vel drive (Fig. 3/6). The electronic travel
drive control realises modification of tra­vel speed, direction as well as dynamic
braking.

3.1.6 Batteries and Charger

The machine is equipped with 235 Ah
batteries (Fig. 3/5), an automatic char­ger unit (Fig. 3/7) and a low discharge
signal sender (LDS) for protection
against low discharge.

3.1.7 Options

• Extraction hose including suction
pipe, joint nozzle and wet suction
nozzle

• Mop holder and tool-box for cleaning
utensils

Accessories such as brushes,
rollers, pads, pad holder with
centerlock and sealing strips
are available. Contact your Mi­nuteman Dealer for more infor­mation.

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, re-adjustment 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 88-60­2556 for information on care of drive
batteries.

5.4.4 Remove 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 ca-

bles.

6. Remove batteries.

5.4.5 Install Batteries

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

1. Switch off machine by key switch.

2. Open empty recovery tank (Fig. 7/7)
and secure by gas pressure spring
(Fig. 7/8).

3. Place batteries into trough according
to figure.

4. Connect battery poles and enclosed
connecting cables according to wi­ring diagram (Fig. 7/9). Provide for
tight fitting and grease poles.

5.4.6 Disposal of Batteries

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

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 6bar.

5.5.2 Empty Solution Tank

Park vehicle 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 Clean Solution Filter

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

Only clean solution filter with
emptied solution tank.

1. Empty solution tank (Fig. 8/1) entlee­ren, see paragraph 5.5.2.

2. Unscrew filter cap.

3. Remove the filter element from the
filter case for cleaning. Replace if re­quired.

4. Re-install filter element and filter
cap.

on the squeegee (Fig. 11/1) weekly for
signs of wear. The sealing strips can be
used fourfold by turning them.

1. Lift the squeegee out.

2. Pull off the suction hose, loosen the
two star-shaped knobs and remove
the squeegee.

3. Unlock the fastening device (Fig. 11/

5) and remove the outer sealing
strip. Turn the sealing strip or install
a new one, as necessary. Change
the inner sealing strip in the same
way.

Maintenance and Care

5.8.3 Adjusting the Sealing Strips
Angle Adjustment

The angle adjustment is the decisive
factor in ensuring that the sealing strips
on the squeegee lie evenly on the floor.

1. Park the machine on a level surface
and lower the squeegee.

2. Loosen the srews on the eccentric
wheel (Fig. 12/1) and adjust the
squeegee using the eccentric wheel
(SW13) so that the ends of the
sealing strips still have contact with
the floor.
Figure A: Turn the eccentric wheel in
the front top position: The clearance
between sealing strip and floor is re­duced in the centre.
Figure B: Turn the eccentric wheel in
the behind top position: The clearan­ce between sealing strip and floor is
increased in the centre.

3. Switch the machine on and check
the suction pattern. When the machi­ne is in operation, the entire surface
of the sealing strips (centre and ou­ter areas) must be applied as evenly
as possible.

4. Tighten the srews on the eccentric
wheel 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 rollers and floor
must be adjusted by changing the num­ber of washers on the holder.

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 110 cm 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.
