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
Hako contract workshops.
Proceed to proper initial charging of the used batteries before first operation of the machine. Hako cannot be held liable
for battery damages resulting
from non-execution of initial
charging.
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 Hako contract workshops
are authorised to proceed to
adjustment of the low discharge signal sender.

5.8.1 Cleaning the Squeegee
Check the squeegee (Fig. 11/1) daily
and clean as necessary.
To clean it lift the squeegee out, pull off
the suction hose (Fig. 11/4), loosen the
two star-shaped knobs (Fig. 11/2) and
remove the squeegee.
5.8.2 Changing the Sealing Strips
Check the inner and outer sealing strips
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/

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.
