tery. The full terms of warranty can
only be accepted when these units
are used.
Before starting the vehicle up
for the rst time, the batteries to
be used must be fully charged,
properly, by implementing the
initial battery charge routine.
PowerBoss assumes no liability
for damage to the battery caused
by a fault when the battery is
charged for the rst time.
The seat console must be pivoted
open during the battery charging
process to prevent the develop-
ment of explosive oxyhydrogen!
Only use the original charger!
Pay attention that the insulation
is not initially damaged and not
damaged during the charging
process. The cable must not rub
against anything. Do not use the
charger if the insulation is dam-
aged.
Do not inhale battery gases.
Please pay attention to the operating
manual provided with the charging unit
as well as the manual from the battery
manufacturer. Powering up the batter-
ies is described in such detail in the
manufacturer’s documents that further
information on the subject is considered
unnecessary for this manual.

Starting Up
2.3 Prior to starting up for the
rst time
The following work must be completed
before starting the vehicle up for the rst
time:
2.3.1 Installing the rotary brushes
Two rotary brushes must be tted in the
rotary brush head. These rotary brushes
are not part of the scope of delivery sup-
plied with the vehicle. Choose the rotary
brushes separately according to the task
to be completed (refer to Section 4). If you
ordered the rotary brushes together with
the vehicle, the rotary brushes are nor-
mally already installed by the authorized
PowerBoss dealer prior to delivery.
Check whether rotary brushes
are tted.
If no rotary brushes are installed, proceed
as follows to install them.
The following applies to all work
on the rotary brushes: Turn the
key switch to position 0, remove
the key and apply the parking
brake (Fig. 14/8).
The front rotary brush is changed
from the right-hand side of the
vehicle, the rear rotary brush from
the left-hand side of the vehicle.

2.3.2 Installing and adjusting the
squeegee
Installing the squeegee
1. Switch on the key switch.
2. Lower the squeegee holding attach-
ment: Press the button for the squee-
gee and suction turbine so that the
green control lamp lights up.
3. Switch off the key switch and remove
the key.
4. Open the rear doors.
5. Slide the squeegee from the rear under
the lowered holding attachment and x
the squeegee to it with the four wing
nuts (Fig. 9/1).
6. Attach the suction hose to the connec-
tion nozzle (Fig. 9/2) of the squeegee.
7. Insert the key in the key switch and
turn the key switch on.
8. The squeegee is then lifted automati-
cally.
9. Close the rear doors.
Fig 9
Adjusting the squeegee
The squeegee must be set up on a level
oor according to the conditions in which
it is to be used. The squeegee must stand
vertically on the oor (adjusted at the fac-
tory). The sealing strip (Fig. 9/3) should
bend slightly to the rear when the vehicle
is in operation. Supporting rollers (Fig.
9/5) limit its movement toward the oor. To
increase the squeegee contact pressure,
the supporting rollers must be adjusted:
• Loosen the counternuts (Fig. 9/4) and
raise the supporting rollers on the left
and right evenly (turn screw counter-
clockwise and lock again).
The sealing strip now bends a little more
towards the rear. An adjustment of the
supporting rollers is also necessary when
the edge of the sealing strip is worn.
