Note
Indicates useful tips and important information about
the product.
The appliance is used for the wet cleaning of level
floors.
A working width of 300 mm and a capacity of 4 l each
of the fresh and dirt water reservoirs enable an effec-
tive cleaning of smaller surfaces.
The power supply operation allows a high capacity
without a restriction of the working time.
–
The appliance can be used in a forward motion by
pushing it and backwards by pulling it by the han-
dle.
The fresh water tank must be filled with the correct
mixture of water and detergent prior to operation. The
detergent solution flows to the brush head via a water
pump and is revacuumed by two vacuum bars.
–
Content of fresh water tank: 3.7 l
–
Content of wastewater reservoir: 3.7 l
The suction turbine (M1) produces a vacuum pres-
sure in the wastewater reservoir, which pulls the
wastewater from the vacuum bar to the wastewater
reservoir.
If the wastewater reservoir is full, the float closes the
suction opening.
The wastewater reservoir can be removed from the
appliance for cleaning purposes.
Note
The suction turbine (M1) does not switch off automat-
ically when the wastewater reservoir is full. Only
when you press the main switch, the suction turbine
(M1) will shut off.
For the appliances BR 30/4 C and BR 30/4 C Bp
Pack, it is possible to lift the suction bar and perform
a wet cleaning only.
The BR 4.300 does not have a suction bar lift.
The vacuum bar can be replaced without the use of
tools.
The switches for the operation of the appliance are lo-
cated in the handle and on top of the housing.
–
The main switch (S1) for brushing and vacuuming
operations are located on top of the housing.
–
The switch (S2) for the operation of the water
pump (M3) is located in the handle.
