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 hopper
(Fig. 20/7) must be checked daily for
signs of dirt and cleaned as necessary.
Only Minuteman KS 28 B:
Tapes winding around the rota-
ry brush leads shutdown due to
overloading!
1. Remove the dirt hopper,
refer to Section 5.9.1.
2. Check the brush space - the area be-
tween the rotary brush, panel air fil-
ter and dirt hopper - 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.
5. Change defective dirt hopper seals,
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 9.9
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 two 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 arranged in a V-shape in the di-
rection of driving so that the dirt is guid-
ed to the center of the rotary brush.
1. Tip the machine to the rear.
Before tipping the Minuteman
KS
28 B, the battery must be
removed, refer to Sec-
tion 5.5.4!
Before the Minuteman KS 28
can be tipped back, the han-
dlebar must be adjusted 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.
