General Information

– The unit is the successor to the BR/BD 530.

– Abbreviations:

Ep = Mains powered

Bp = Battery powered

Bp Pack = Battery powered with integratedcharger

C = Compact (without drive system)

W = Walk behind (Bp Pack only)

Drive system (W Bp Pack only)

– 24 V 130 watt electric motor with freewheelingfunction.

– Oil resistant wheels.

– Transport roller extended/retracted using footpedal:

– for relieving the brush rollers after finishingthe work.

– for unit transport.

Brush system

BR version:

– BR brush head with brush quick-changesystem.

– 2 brush rollers, effective working width 550m m(BR 55/40), and 450 mm (BR 45/40).

– Brush drive assembly system with toothedbelt (similar to BR Vario).

BD version:

– 1 disc brush with quick-change system.

– Brush drive assembly system with toothedbelt (similar to BR 530).

Vacuum system

– Suction motor(Bp = BR/BD 530, Ep = BR/BD 40/25).

– Mechanical float.

– Suction bar, straight version only.

– Suction bar is lowered/raised manually.

Brush drive assembly

– 24 V electric motor.

Water system

– No water pump, the water flows to the brushhead by gravity.

– Water volume control through ball valve (similarto BR/BD 530).

– Automatic water stop when brush stops dueto solenoid valve water stop(= BR/BD 40/25 C).

– Level indicator of the freshwater tank.

– Tank-in-tank system (2-piece).

– Freshwater tank (40 l).

– Dirty water tank (40 l).

Electrics

Ep version:

– Operator presence control handle (similar toBR/BD 40/25 Ep).

– 6-stage program selection switch (mechanicaldecoding switch).

Bp version:

– Indicator lamp, battery monitoring.

– Indicator lamp, fault.

– FACT rpm adjustment. 3 adjustment levels(Power/Whisper/Fine), manufacture setting:Power.

– Clean Speed adjustment, 5 adjustment levels(20% - 100%), manufacturer setting 60%.

– Operator presence control handle withmicroswitch (= BR/BD 530).

– 6-stage program selection switch (mechanicaldecoding switch).

– Integrated charger (Bp Pack only).

– Batteries 100 Ah, maintenance free (Bp Packonly).

– Charger 230 V, 15 A (± 10%), IUIacharacteristic curve (Bp Pack only).

– Standby mode, switches off after 30 minutes.

Troubleshooting BR/BD 55/40 45/40 C Ep, C Bp, W Bp Pack

Page 58 / 60

7.1 Troubleshooting without displays

Fault

Unit won’t start

Solution

– Check whether the mains plug is plugged in (Ep only).– Unit is in standby mode/program selection switch is set to

Position „1“ (Drive/OFF) and then switch to required program(Bp only).

– Connect/check/charge batteries (Bp only).– Check battery charge control (Bp only).– Check/replace fuse (F1) (Bp only).– Check/replace program selection switch (S1/S2).– Check/replace unit switch with motor protection switch (Q1)

(Ep only)– Check/replace main control printed circuit board (A1).– Check whether charger (U1) is plugged in/unplug

(Bp only).– Check/replace charger (U1) (Bp only).

No or too little watersupply
