Maintenance and Service
5.8.1
Cleaning the brush space
The brush space with the rotary brush
(Fig.
20/1) and seals for the dirt hop-
pers (Fig.
20/7) must be checked daily
for signs of dirt and cleaned as neces-
sary.
Only PowerBoss Collec-
tor 34 B:
Tapes winding around the rota-
ry brush leads shutdown due to
overloading!
1. Remove the dirt hoppers, refer to
Section 5.9.1.
2. Check the brush space - the area be-
tween the rotary brush, panel air fil-
ter and dirt hoppers - for residual
waste and damage.
3. Remove any foreign bodies.
4. Clean the brush space, firstly with a
hand brush and then with water. Dry
the brush space.

refer to Section 5.9.4.
5.8.2
Changing the rotary brush
The rotary brush (Fig.
20/1) must be
checked weekly and changed in the
case of wear. A new rotary brush has a
diameter of 9.8
in. When a rotary brush
has a diameter of only 7.9
in,
it
must
be
replaced with a new one.
The rotary brush (Fig.
20/1) is com-
prised of four individual rotary brush
segments (Fig.
20/2)
which
are
fixed
to
the rotary brush shaft
(Fig.
20/5) by the screws (Fig.
20/4).
Pay attention that the bristle pattern on
the rotary brush (Fig.
20/1)
is
always
ar-
ranged in a V-shape in the direction of
driving so that the dirt is guided to the
center of the rotary brush.
1. Tip the machine to the rear.
Before tipping the Power-
Boss Collector 34 B, the bat-
teries must be removed, refer
to Section 5.5.4!
Before the PowerBoss Collec-
tor 34 B/G can be tipped back,
the handlebar must be adjust-
ed to a vertical position.
2. First of all, disassemble the two adja-
cent rotary brush segments
(Fig.
20/2): Loosen the screws
(Fig.
20/4) and remove the rotary
brush segments (Fig.
20/2).
3. Then turn the rotary brush shaft
(Fig.
20/5) 180º by hand and disas-
semble the two remaining rotary
brush segments (Fig.
20/2).
4. Assemble four new rotary brush seg-
ments (Fig.
20/2) in the reverse se-
quence. When doing so, pay atten-
tion that the rotary brush segments
(Fig.
20/2) are installed on the guide
pins (Fig.
20/6) of the rotary brush
shaft (Fig.
20/5) and screw to facing
rotary brush segments
(Fig.
20/2) firmly to each other.
5. Tip the machine back up again.
