2.5 Operation
1. Switch the machine on using the key
switch. All the units are in Standby
2. Lower the squeegee using the
squeegee lever. The suction turbine
is switched on.
3. Lower the brush head using the foot
pedal.
4. Pull the bar on the bail system. The
brush head drive is switched on.
5. Set the solution quantity using the
button on the operating panel.
6. Set the driving direction and speed

7. To alter the cleaning intensity of the
cleaning process, use the buttons on
the operating panel to change the
solution quantity and switch the solu
-
tion supply on and off.
Start driving immediately after
switching on the brush head
drive otherwise imprints of the
brush could be produced on
the floor. Raise the brush head
when driving over thresholds.
2.5.1 Useful tips
Before beginning wet cleaning, sweep
the floor. This not only improves the
cleaning effect but also reduces the machine's liability to wear.
The floor should be treated twice in the
case of particularly dirty floors or to remove wax (thorough cleaning). During
the first cleaning process, the floor is
scrubbed with a cleaning agent dosage
appropriate to the degree of soiling,
whereby the squeegee is raised.
The cleaning agent is left to act on the
floor for approx. 5 to 10 minutes according to the manufacturer's instructions,
then scrub the floor again and, after
that, treat it with the squeegee lowered.
Pay attention to the correct
dosage of the cleaning agent.
The correct dosage helps to re
duce costs and protect the environment. The development
of excessive foam impairs the
machine's function. It indicates
there is too much cleaning
agent or the wrong one has
been selected for the cleaning
process being completed. Un
-
used component parts of a
cleaning agent which end up in
the waste water lead to the de
velopment of foam. Information on dosage is provided on
the cleaning agent container.
Use the manufacturer's infor
mation as an initial basis. Practical experience will ensure
that you quickly find out which
is the right Hako cleaning
agent and the optimum dosage
to suit your needs.

5.4.1 About Quick Charge Technology
• The Quick Charge Technology lets
you extend the everyday machine
usage time by intermediately charg
-
ing the batteries during idle periods.
• At the beginning of a charging cycle,
a very high charging current is sup
plied for 10 minutes to provide extra
capacity for immediate use. Quick
charging is possible if two or three
segments are shown on the status
indicator.
• To complete a full charging cycle,
just leave the machine connected to
the quick charger. The unit will automatically change from quick to standard charging mode.
• Completely charge the batteries at
the end of your daily cleaning work.
Mind that the number of daily
quick charging cycles is limited
to four. Exceeding this limit
may greatly heat up the batteries and cause premature failure.

5.4.2 Charging batteries
Complete an initial battery
charge cycle to properly
charge the batteries prior to
running the machine for the
first time. Hako assumes no li
ability for damage to the battery caused by a fault when the
battery is charged for the first
time.
Ensure sufficient ventilation in
the charging area when charg
ing the batteries – risk of explosion!
Scrubmaster B45 CL DTC features two
AGM/Optima YTS 5.5 batteries (Fig.
10/6) providing a rated capacity of 75
Ah.
You can charge the batteries if at least
one charge status indicator segment
has extinguished after operating the
machine.
Only use charger E230 G24/90 B25-FP
from the package (Fig. 10/2) to charge
the batteries. This is the only charger
with a set charge characteristic curve
specifically adapted to the on-board
Optima batteries YTS 5.5.
1. Turn the machine off.
2. Disconnect the plug from the machine's battery connector (Fig. 10/4).
3. Plug the charger's battery connector
(Fig. 10/3) into the machine's battery
socket.
4. Turn on the quick charger. Refer to
the table (see section 5.4.1) for the
correct charging time.
5. While charging, the display of the
quick charger shows the battery
charge status.
6. To stop charging: turn off the quick
charger. Pull the plug off the ma
chine's battery connector and plug in
the machine's battery plug.
Read and take heed of the
charger instructions and the
manufacturer's user guide.
5.4.3 Total discharge signal transducer (TSG)
The machine features a total discharge
signal transducer to prevent total battery discharge.
The TSG is set to the built-in batteries at
the factory. The TSG needs to be
adapted to other batteries approved by
Hako.
The total discharge signal
transducer may only be adjusted by a licensed Hako workshop!
39
Maintenance and Service
5.4.4 Charge status indicator
During operation, the charge status of
the batteries is displayed in the indicator field (Fig. 10/1). The charge status
indicator is connected to a total discharge signal transducer (TSG) in the
machine control unit. Four segments on
the display are indicative of the batteries being fully charged. The segments
extinguish one by one as more power is
drawn from the batteries. At the discharge limit, the battery icon starts to
flash and the TSG turns off the cleaning
functions to prevent total battery discharge (machines with a traction drive
can still be moved at reduced speed).
Charge the batteries immediately!
5.4.5 Replacing the batteries
Due to the dedicated charging
technology, no other batteries
than the special AGM types
approved by Hako must be
used!
Batteries to be replaced by
qualified service technicians
only!
We recommend our licensed
Hako Customer Service.
5.4.6 Servicing the d riving batteri es
Never keep discharged batteries but recharge them immediately!
For information on servicing
driving batteries, refer to product sheet 88-60-255.
5.4.7 Disposing of batteries

Maintenance and Service
Height adjustment
The height adjustment is set to 3 mm at
the factory. If streaks appear despite an
optimum angle adjustment, the distance of the rollers to the floor must be
adjusted by changing the number of
washers on the holder.
In the case of very smooth floors, e.g.
varnished floors, linoleum etc.:
Number of washers = 2. This corresponds to a distance of approx. 2 mm to
the floor.
In the case of very uneven floors, e.g.
badly laid tiles (water does not run off):
Number of washers = 4. This corresponds to a distance of approx. 4 mm to
the floor.
