1 Introduction
This operating manual contains instructions for using the hand-operated
sweeper.
Our products are subject to continuous improvement. Therefore, design
changes that were made after this manual went to print could not be
incorporated. If you have any questions, please contact our Service
department.
The operating manual must be read and applied by all persons who
operate the sweeper.
Apart from the operating manual and the regulations for accident pre-
vention applicable in the country of use and the location of use, the
common, recognised rules for safe and technically correct working must
also be followed.
1.1 Usage conformant with intended purpose
The appliance is intended exclusively for sweeping on solid surfaces (for
example: parking areas, walkways, shop floors). The area to be swept
should not be wet.
The sweeper may only be used by reliable and instructed personnel.
Prevent children, juveniles and other unauthorised persons from using
the machine (e.g. by pulling out the key after use).
Any other use, or any use over and above that, will be considered to be
non-conformant with intended purpose. The manufacturer rejects any
and all liability for damage resulting from such use. The risk is that of the
user alone.
Usage conformant with intended purpose also includes compliance with
the operating manual and the inspection and maintenance specifica-
tions. Drive the sweeper only along expressly marked routes and spac-
es.

TF90-TRS 5
16. Charge flat batteries directly after use and only in well-
ventilated rooms.
17. Keep naked flames and electrical sparks away from the
charging area, since a highly-explosive electrolytic gas mix-
ture is generated when batteries are being charged.
18. Note that the accumulator batteries are filled with battery ac-
id.
19. Batteries should always be kept clean and dry to avoid
leakage currents! Never short-circuit battery poles!
20. Smoking, eating and drinking should be avoided in the vicin-
ity of the battery charging station to avoid risks to health.
21. Batteries should only be charged with the hood opened and
secured with the holder.

3 Sweeper description
3.1 Sweeper description
The battery-operated sweeper has been equipped with two side brushes
and two counter-rotating brush rollers.
The sweeping mechanism features two side brushes which convey the
refuse to the two brush rollers that are mounted parallel to the direction
of motion.
The brushes throw the refuse overhead in the rear dirt collector.
A chain drives the brush rollers, and a V-belt drives the side brushes
through the forward motion of the running wheel.
The top model is the TF90VB-TRS, which has been equipped with a
dust extraction unit (V) and a main broom drive (B).
The modular design of the TF90-TRS series allows for retrofitting the
TF90-TRS with a brush roller drive (standard model features a dust
extraction unit) and the
TF90V-TRS with a dust extraction unit (standard model features a brush
roller drive).
The electronic system provides for a soft start feature, which ensures
that the drive does not run at full power all of a sudden.
The TF90-TRS sweeper is driven by manual power only, in other words,
by pushing the driving hoop.
The brush roller drive of the TF90B-TRS and the TF90VB-TRS does not
serve as a drive unit.

3.2 Initial start-up
Unpacking and assembly
Open the packaging and carefully lift the machine off the pallet.
Danger of Injuries!
Reach under the frame of the machinery to lift it. There is a risk of injury
if you attempt to lift the machinery at the hood, the side brush retainer,
or the hopper.
Place the driving hoop on the retainers.
Slide the square necked bolts through the bore holes in the driving
hoop and the retainer.
Use the star knobs to secure the square necked bolts. Set the side
brush arms to the top position.
Position the side brushes under the side brush retainers.
Turn the side brushes until the bore holes of the side brush disc line
up with the pins of the side brush retainer.
Push the side brushes into the side brush retainers until you feel the
side brushes lock into place.
Connect the battery.
The sweeper is ready for operation.
CAUTION!

4 Operation
4.1 Sweeping
Lower the side brushes until the tips touch the ground.
To turn on the desired sweeping function, select and push the button for
the desired function on the control panel.
Always use the button on the left first, regardless of the model.
(Models B and VB: Turn on the main broom drive/Model V: Make ready
for operation)
Only then push the button on the right on the V and VB models. (Dust
extraction unit on)
No function has been assigned to the button on the right on the TF90-
TRS.
Push the sweeper across the area to be swept at a normal pace.
Since the sweeping performance depends on the speed of the brush
rollers, you should neither walk too slowly nor too quickly. (e.g. run)
The side brushes remove dirt from corners and edges.
4.2 Height adjustment of the side brushes
The side brush arms are located on the front side of the sweeper.
The height adjustment fixtures for the side brushes are located on the
side brush arms.
You can lower or raise both or just one side brush as needed.
To lower a side brush:
Push the lever of the side brush adjustment fixture to the front.
To raise a side brush:
Pull the lever to the back.

TF90-TRS 9
4.3 After sweeping
Push the respective button on the control panel to turn off all the
actuators and park the sweeper in a safe location.
Empty the hopper in a suitable container.
Make sure the container is appropriate for this type of refuse.
Insert the hopper back into the sweeper. Set the side brushes to their
top position.
Unless the side brushes are set to their top position, the bristles of the
side brushes will be put under permanent load in their off-position and
consequently will wear prematurely when used.
4.4 Emptying the hopper
In order to ensure proper sweeping performance, the hopper has to be
emptied at regular intervals.
A handle is located on the top of the hopper.
Hold on to the handle and lift the hopper out of the sweeper's frame.
Empty the hopper in a suitable container.
Insert the hopper back into the sweeper.
Do not park the sweeper with a full hopper. Always empty the hop-
per once you've finished sweeping.

5 Maintenance
5.1 Safety Information
Only complete the type of maintenance work described in the following
chapter. All other maintenance and upkeep work may only be carried
out by the manufacturer or by companies and persons authorised by the
manufacturer, who are familiar with the relevant safety specifications,
because portable devices in industrial use are subject to the safety test
according to VDE 0701.
Closely follow the steps listed in the maintenance instructions. The im-
proper completion of maintenance tasks may result in malfunctions
when using the sweeper and may possibly render the warranty granted
null and void.
When working on the electrical system, the battery should be discon-
nected.
Maintenance work/ troubleshooting at the electric motor must not be
done while the electric motor is running.
Use only flawless and appropriate tools to complete maintenance work.
Note the requirements for spare parts.
If covers and/or safety devices were removed during maintenance
work/repairs, they will have to be reattached prior to starting the sweep-
er.
For carrying out any work on the sweeper, it must be switched off and
secured from rolling away by accident.
5.2 Cleaning
The suction sweeper may only be cleaned in the off state, when it is dry.
The suction sweeper is a machine with electrical components.
Moisture damages the electronics of the device. Moisture can re-
sult in leakage currents and short-circuits!
Do not use any high-pressure cleaners
WARNING

TF90-TRS 11
5.3 Readjusting the main brooms
The height of the main brooms can be adjusted to obtain the best possi-
ble cleaning results of the area to be swept and to effectively exploit the
efficiency of the main brooms.
The main brooms need to be lowered once the sweeping performance
starts to wane due to wear and tear of the main brooms, or if the area to
be swept is not level.
If pushing the sweeper seems to become harder and you can hear the
main brooms scratching the ground, you will have to raise the main
brooms to ensure you use the sweeper ergonomically and to prevent
the main brooms from wearing prematurely.
On principle, the main brooms should be set to ensure that they touch
the ground at slight pressure.
5.4 Setting the main brooms
Park the sweeper on level ground that has been designated (as-
signed) for this purpose.
Make sure the sweeper has been secured from rolling away by ac-
cident.

TF90-TRS 15
5.11 Filter cleaning
To consistently attain the best possible cleaning results, you must al-
ways clean the lamellar filter prior to emptying the dust bin.
Likewise, you should also clean the filter if particularly dusty areas are
swept, or if dust is whirled up during sweeping.
The sweeper has been equipped with a mechanically operated vibrating
device to clean the lamellar filter.
Turn off the sweeper (all actuators).
Make sure the sweeper has been secured from rolling away by ac-
cident.
Open the hood.
On the top of the ejector's trim panel -3- two slides -1- are located.
Swiftly slide these slides back and forth.
These slides initiate a vibrating mechanism, which works loose the dust
from the lamellar filter. The worked off dust drops directly into the hop-
per.
To remove stubborn dirt, you should use a brush to clean off the filter or
take out the filter and gently knock off the dirt.
