1.2 Introduction
The DRT (Driven Rotary Tool) is a tool for quickly cutting thin leather and textiles. The extremely high
rotational speed (12000 - 20000 rpm) means that wear on the drive unit is inevitable. The levels of
stress and wear on the tool are also heavily influenced by the following factors:
• Material texture
• Material thickness
• Blade shape and dimensions
• General operation
Manufacturing tolerances may result in audible fluctuations in the rotational speed. The tool remains
fully operational despite these fluctuations and can be used until it fails.

2 Safety requirements
2.1 Protective clothing and equipment
When operating, cleaning or maintaining the equipment, wear only close-fitting clothing and personal
protective equipment suited to the task at hand.
The following protective equipment is required:
• Work clothing
• Safety goggles
• Protective gloves if there is a danger of being burned or injured by pointed or sharp-edged objects
• Ear protection if the continuous sound pressure level is over 85 db(A).
Important:
You are responsible for:
• using the required personal protective equipment;
• cleaning and maintaining the equipment on a regular basis;
• promptly replacing damaged and unusable parts of protective equipment
2.2 General
Important:
These safety requirements and notes only represent tool-specific supplements to the "Safety
requirements" chapter in the cutter operating manual.
This chapter:
• defines the proper use of the tool;
• contains tool-specific safety precautions and instructions;
• provides information on the protective equipment required for work and maintenance.
Special operational and situation-specific safety requirements are listed in the relevant processing
steps in subsequent chapters of this manual.
2.3 Intended use
Safe operation is guaranteed when the equipment is used solely for its intended purpose.
The equipment provided determines the possible uses of the tool.
The DRT is essentially designed to cut soft materials such as leather and textiles using the universal
module.
Any other use which does not meet this description shall be classed as improper use. The user bears
sole liability for any damage arising as a result of improper use.
The tool is deemed to be used as intended under the following conditions:
• all national safety regulations are observed
• the safety instructions listed in this operating manual are observed
7
Safety requirements
•
the operating conditions are observed and the recommended materials are used
2.4 Examples of improper use
•
•

Safety requirements
2.6 Safety signs
The equipment is fitted with important safety signs; failure to observe these signs can result in serious
injury.
Warning:
Safety risks due to missing or illegible safety signs.
• Check all safety signs on a regular basis for legibility and completeness.
• Replace missing or illegible safety signs promptly with new original signs.
Meaning of safety signs
The symbols on the safety signs:
• have specific meanings;
• are located wherever certain behaviour is prohibited due to it being potentially dangerous
Order signs
These symbols:
• are blue and circular;
• stipulate the wearing of personal protective equipment to protect against hazards
Wear eye protection

1-1-1-3-1-7 Raise if overcurrent
If too much force is used to stop the DRT during
processing (e.g. because the material is too
tough), overcurrent occurs. If the function is
activated, the tool is raised in the event of
overcurrent.

Controls and operation
3.5 Putting the DRT into operation
3.5.1 Initialization process
Caution:
Risk of injury during tool initialization!
The front light barriers are not active during manual initialization!
• Do not touch the operating area of the tool during initialization.
• Define the zero point with the ITI.
Tip:
Initialization can be carried out manually or automatically with the permanently installed ITI.
1-1-1-2-1 Define Z init pos
1-1-1-2-2 Auto init
1-1-1-2-3 Up Z pos
16
Set the tool manually or via ITI to
exactly the height of the cutting
underlay.
The value determined is used as the
starting point for the settings upper
position and lower position.
The upper position defines the gap
between the zero point and the raised
tool.
Select this value in accordance with
the material and its folding properties.
A short distance between processing
material and raised tool generally
means a shorter processing time.
Controls and operation
The lower position defines the
processing depth of the tool. Pressure
is built up on the material from the set
depth.

3.5.2 Carrying out a test cut
A Place the material to be processed on the working surface.
B 1-1-1-2-5 Test cut Select.
C Use the travel keys to position the tool over the material.
D Press OK to continue.
A test cut is created.
E Check the test cut.
Has the set cutting depth not been reached?
The performance of the tool is constantly monitored. In the case of an overload (incorrect material,
incorrect settings), the tool is lifted out of the material until the normal load is reached.
F Check that the material is suitable to be processed using DRT.
G Change settings (acceleration, speed, etc.).
