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, and 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.

3 Sweeper description
3.1 Sweeper description
The suction sweeper is driven by an electric motor.
Sweeping is done with two side brushes which convey the refuse to the
two main brooms that are mounted at 90 degrees to the direction of
motion. The rollers throw the refuse overhead in the rear dirt collector.
The dust that is collected by the main brooms is kept in a lamellar filter
in the machine by the dust extraction.
The lamellar filter can be cleaned by a manually actuated filter vibrator.

4.4 After sweeping
Switch off the machine.
8 TF91-TRS
Adjust the side brushes and main brooms in the upper position.
If the main brooms are not set to their top position, the bristles of
the side brushes will be put under permanent load in their offposition and consequently will wear prematurely when used!
Always empty the dustbin once you've finished sweeping.
4.5 Setting the traversing mechanism
The traversing mechanism can be readjusted at the adjusting screws at
the handle and at the belt tensioner.
Adjust the belt tensioner in such a way that the belt lies loosely on
the handle without tension.
It should be possible to press the belt 4 cm inwards in the middle till the
first resistance is felt.

The sweeper does not have any brakes.
Therefore, secure the sweeper against rolling away (e.g: wheel
chocks).
Turn the key in the anticlockwise direction to switch off the motor
and pull out the key.
Improper handling of the suction sweeper can result in harm to
persons and property!

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
5.3 Filter cleaning
Make sure the dust collector has been installed.
Move the filter cleaning lever -1- back and forth a few times.
WARNING
TF91-TRS 11
