3.1 Method of operation
The Kleen Sweep 25W is a machine
designed to sweep and clean waste
from hard floors and carpets.
The side brush (Fig. 4/1) sweeps the
dirt from corners to a position in front of
the rotary brush (Fig. 4/2). The rotary
brush sweeps the larger particle dirt
overhead into the sweepings container
(Fig. 4/3). The finer dust picked up is
drawn up by the suction turbine, fed into
the filter system (Fig. 4/4) and filtered
out. Only dust-free air is fed back into
the ambient air.
The machine is equipped with maintenance-free batteries (Fig. 4/5), a specially adapted, fully automatic battery
charger (Fig. 4/6) and a total discharge
signal transducer to protect it against
total discharge.
Please refer to the spare parts
catalogue on our internet site
at www.Minuteman.com for
accessories, such as brushes
and rotary brushes.

Operation
Control lamp for rotary brush drive,
side brush drive and suction turbine
(Fig. 5/2)
The green control lamp indicates that
the rotary brush drive and suction turbine are ready to operate. If the rotary
brush or suction turbine are overloaded,
a safety shutdown is triggered and the
control lamp flashes.
ON/OFF button for rotary brush, side
brush and suction turbine (Fig. 5/1)
The button activates the rotary brush
drive, side brush drive and suction turbine so they are ready to operate.
The side brush drive can be switched
off separately. The suction turbine cannot be switched off separately which
prevents the dust vacuum being activated by accident.
To prevent unauthorized use
of the machine, switch the machine off using the button (Fig.
5/1).
Control lamp for side brush drive
(Fig. 5/4)
The green control lamp indicates that
the side brush drive is ready to operate.
If the side brush is overloaded, a safety
shutdown is triggered and the control
lamp flashes.
ON/OFF button for side brush drive
(Fig. 5/3)
The button can be used to swit ch off the
side brush drive independently of the
rotary brush drive and to activate it for
use again.
Control lamp for battery charger
operation (Fig. 5/5)
This control lamp indicates that the batteries are being charged.
Charge control indicator (Fig. 5/6)
During the charging process, the machine's electronics system controls the
machine is not switched on inadvertently and indicates the charge status. The
battery charge status is indicated by 4
green and 1 red LED.
The battery voltage is depicted in 5 levels:
>
25.1 V = all green LEDs on
>
24.5 V = bottom 3 green LEDs on
>
23.9 V = bottom 2 green LEDs on
>
22.7 V = bottom green LED on
< 22.7 V = red battery LED flashes
Drive bar (Fig. 5/7)
The drive bar switches all the drives
which are ready to operate on or off.
The drive bar serves to prevent damage. If the drive bar is released during
operation, all the drives are switched
off.

5.4.1 Charging batteries
The charge control indicator (Fig. 7/2)
indicates the charge status of the batteries during operation. The batteries
must be charged immediately the red
LED lights up. The batteries (Fig. 7/7)

charged, the battery indicator on the
charger (Fig. 7/1) lights up.
Before starting the machine up
for the first time, the batteries
to be used must be fully
charged, properly, by implementing the initial battery
charge routine. Minuteman
assumes no liability for damage
to the battery caused by a fault
when the battery is charged
for the first time.
5.4.2 Total discharge signal transducer (TSG)
The machine is equipped with a total
discharge signal transducer to protect
the batteries against total discharge.
The total discharge signal transducer is
integrated in the electronics. If other
batteries are used, the total discharge
signal transducer must be adjusted.
The total discharge signal
transducer may only be adjusted by an authorized Minuteman
service center.
