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 prevention 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 specifications. Drive the sweeper only along expressly marked routes and spaces.

2 Safety information
1. The machine should only be used in a flawless state, as
well as in keeping with its intended purpose, in a safetyconscious and risk-conscious manner and in compliance
with these operating instructions.
2. In addition to the operating manual, please heed general legal and other binding regulations for accident prevention
and environmental protection.
3. Sweeping and picking up of flammable, toxic or explosive
substances, along with flammable gases or diluted acids
and solvents, burning or smouldering objects is prohibited!
4. The appliance is not suitable for picking up fluids, cables,
cords, wires or the like.
5. The machine should only be used with the dust box fitted to
prevent injuries caused by parts being slung out.
6. Transporting loads with the sweeper is not allowed.
7. Faults should be eliminated immediately, particularly those
that could impair safety.
8. Do not make any changes, modifications or additions to the
sweeper without the approval of the manufacturer.
9. Replacement parts must meet manufacturer specifications.
This is always ensured by using original replacement parts.
10. Ensure that operating media, auxiliary media and replacement parts are disposed of in a safe and environmentallyfriendly manner, particularly batteries!
11. Suitable non-slip footwear should be worn to avoid accidents.
12. If you have any questions, please contact our Service department.
13. Persons (including children) who are not able to use this
machine safely due to their physical, sensory or mental capabilities or their inexperience or lack of knowledge may not
use this machine without the supervision or instruction by a
responsible person! Children should be supervised to ensure that they do not play with the appliance.
14. Caution: loose clothing can be caught and drawn in on rotating parts.

Page 7
TF90-TRS 5
16. Charge flat batteries directly after use and only in wellventilated rooms.
17. Keep naked flames and electrical sparks away from the
charging area, since a highly-explosive electrolytic gas mixture is generated when batteries are being charged.
18. Note that the accumulator batteries are filled with battery acid.
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 vicinity of the battery charging station to avoid risks to health.

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 TF90TRS.
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.
Page 11
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 improper 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 disconnected.
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 sweeper.
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 result in leakage currents and short-circuits!
Do not use any high-pressure cleaners
WARNING
Page 13
TF90-TRS 11
5.3 Readjusting the main brooms
The height of the main brooms can be adjusted to obtain the best possible 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.
Open the hood.
The rear trim panel of the frame reveals the height adjustment bracket
to adjust the height of the brushes.
5.5 To lower the main brooms
Undo wing nut -2- on the height adjustment bracket -1-.
Push down the rocker arm -3- in the direction of motion.
The brush rollers are lowered.
Tighten wing nut -2- on the height adjustment bracket -1-.
Test the sweeper.

5.6 To raise the main brooms
Undo wing nut -2- on the height adjustment bracket -1-.
Push down the rocker arm -3- in the direction of the hopper.
The brush rollers are raised.
Tighten wing nut -2- on the height adjustment bracket -1-.
Page 14
12 TF90-TRS
Test the sweeper.
5.7 Removing the main brooms
Every brush roller consists of two split shells with brushes. Screws join
the split shells.
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.
Remove the hopper.
Turn the sweeper on its back.
Make sure the running wheels can move freely.
Turn the top running wheel until you can see the screwed connec-
tions on the brush roller.
Undo the screwed connections.
Lift the split shells with the brush rollers off the shaft.
If needed clean the running gear box and the shaft.
5.8 Installing the main brooms
The split shells have square recesses, which retain the main brooms
shaft.
Position the first split shell under the square shaft of the brush roller.
Make sure the shaft fits flush into the recess of the split shell.
Position the second split shell on top of the square shaft of the
brush roller.
To tighten use three screws for each set of brushes. Tighten until
you can no longer see a gap between the split shells.

the ejector -2-
in the direction of the hopper retainer
Page 17
TF90-TRS 15
5.11 Filter cleaning
To consistently attain the best possible cleaning results, you must always 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 hopper.
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.

5.12 Changing the chain
De-tensioning or tensioning of the chain is preceded by turning/
moving the DC-motor or the sprocket-support.
Position the machine on an appropriate surface.
Make sure the machine is blocked against possible movement
Open the cover.
Loosen the screws of the DC-motor or the sprocket-support to move
the support by rotating it around the front/ first screw.
By lowering the DC-motor or the sprocket-support, the chain is de-
tensioned e.g. for changing the chain.
Moving up the DC-motor or the sprocket-support tensions the chain.
Tighten the screws before operating the machine.
The tension of the chain is supported by the automatic chain-
tensioner.
5.13 Charging the battery
The machine has an on-board-charger.
Position the machine on an appropriate surface close to a socket.
Switch the machine completely of.
Make sure the machine is blocked against possible movement
Open the cover.
Connect plug 1 of the charger using the cable delivered with the ma-
chine and connect plug 2 to the 230 V socket.
Only the original charging-cable is to be used: the use of a different
cable makes you lose warranty on the machine and might cause damage.
-1- ready/battery charge ok
-2- ready/battery charge low
-3- ready/battery charge not ok
When charging is finished, the green LED on the charger will on. (Mean-
ing of the LED: see appendix: operator’s manual of the charger).
The machine can only be operated if disconnected after charging.
Make sure the machine is charged before use. The charger contains an
electronic device that keeps current of the battery on a constant level so
the machine can be kept on the charger for a longer period without
causing any damage.
The machine contains a deep-discharge protection and automatically
switches of if such level is reached to protect battery from damage.
