Operation
Indicator for function
faults
(Fig. 19/5)
The control lamp lights up
red when one of the following
faults occurs:
• The thermostatic switch of the brush
motor, hydraulic motor, side scrub-
bing brush or rotary brush has
tripped.
• One of the safety fuses is defective
or an electronic fuse has been
tripped.
• Another fault has occurred.
At the same time, a four-digit code ap-
pears in the display of the service indi-
cator (Fig. 19/6). This error code infers
which fault has occurred (refer to Sec-
tion 3.5.1). At the same time, the control
lamps flash and an acoustic, pulsating
signal is issued.
Operating hour coun-
ter
(Fig. 19/6) The four-digit
LED serves to display
the operating hours.
When the key in the key switch is turned
on, one and then two four-digit codes
appear in succession (for further de-
tails, refer to page 43, key switch
(Fig. 20/6)). The operating hours ap-
pear after this.
The counter only operates when con-
sumers are switched on (e.g. hydraulic
or brush motor, suction turbine or pre-
sweep/vacuum unit). At the same time,
a red dot flashes at the bottom right of
the display.
Service indicator
(Fig. 19/6) The four-digit
LED serves for a more
accurate determination
of function faults. If a
fault occurs during operation, a four-
digit code (error code) appears in the
service indicator display. At the same
time, the four dots of the error code
flash in the display and a pulsating
acoustic signal is issued. The control
lamp indicating functional faults lights
up red. Section 3.5.1 provides an over-
view of the error codes which help you
clear functional faults yourself. Clear
the fault before starting to use the vehi-
cle again. If you cannot clear the fault
yourself, note down the error code and
inform the authorized PowerBoss deal-
er responsible for your vehicle.
