Ear protection

Respirator mask

Protective gloves

Protective clothing

Protective boots

Only use genuine spare parts from TYROLIT. Otherwise, personal injury, damage to the equipment and other material damages can occur. Do not install attachments on or convert the equipment without TYROLIT’s written consent.

The danger zone is the area immediately around the floor grinder, particularly near the grinding head and moving parts. No part of the body may be inside this area while the floor grinder is running.

There is a risk of severe injury resulting from the following residual risks:

Grinding tools flying away: Only start grinding when no other persons are in the danger zone. Maintain a safety distance. Change damaged grinding tools. Grinding without a protection cover is prohibited.

Uncontrolled movements and vibrations: Do not connect or disconnect cables when the floor grinder is running.

Getting trapped and caught: Loose clothing or long hair could be caught by the rotating cutting tool. Do not wear loose clothing. Secure long hair in a hair net.

Harmful dust: Inhaling dust can cause respiratory problems and is hazardous. Wear a respirator mask. Ensure adequate ventilation in closed rooms. Use a dust extractor during work.

Poor physical condition: Do not work under the influence of alcohol, drugs, or medication. Do not work when overtired.

Tool quality: Do not use damaged grinding tools. Check tools for damage before assembly.

Danger from a grinding tool continuing to run in an accident: Make sure the floor grinder can be stopped quickly.

General Safety: Death or severe injury can result if safety information is not observed. Ensure the “Floor grinding safety manual” is read and understood.

Only use the floor grinder for grinding, rough grinding and renovating floor coverings and other materials stated in this booklet or recommended by TYROLIT.

Use the floor grinder solely with genuine tools and spare parts from TYROLIT. Otherwise, the CE marking and the warranty will lose their validity.

Only use the floor grinder for dry work.

Binding operating limits and characteristic data can be found in the “Technical data” section.

DANGER: Risk of severe injury due to the floor grinder starting up unexpectedly. Switch off the floor grinder and disconnect it from the mains supply before working on the grinding disc.

INFORMATION: Always use a plastic mallet for mounting grinding tools. Metal hammers can damage the grinding tool and grinding disc.

Assembly:

1. Ensure the tool and tool holder are clean.

2. Push the grinding tool into the tool holder.

3. Secure the grinding tool in the tool holder with a few light taps of the plastic mallet.

Dismantling:

1. To change the tool, detach the grinding tool with a few light taps of the rubber mallet.

2. Pull the grinding tool out of the holder.

DANGER: Risk of severe injury due to a floor grinder suddenly starting up or falling over. Switch off the floor grinder, disconnect it from the mains supply, and make sure nothing can get trapped or squashed when tilting the floor grinder.

Proceed as follows:

1. Make sure the floor grinder is on a solid, horizontal, non-slip surface.

2. Make sure that the connecting cable and dust extractor tube cannot be trapped.

3. Move the handle unit (A) up to the open/tool change position.

4. Tilt the floor grinder (B) backwards until you can access the grinding disc holders.

Yes, the floor grinder can be dismantled into two parts for transport: the motor/grinding head assembly (B) and the handle/chassis assembly (A). Follow the instructions for separating these components.

DANGER: Danger of crushing. Use both hands to adjust the handle.

The height of the handle can be adjusted without tools. Adjust the handle to suit the individual user. When adjusting, make sure that the handle lock engages correctly in the desired position.

Using the angle adjustment unit, the floor grinder can be set to different work positions:

A: Operating position

B: Transport position

C: Tool change position

Adjust the unit to select the desired position.

1. Ensure the mains voltage matches the specifications on the type plate.

2. Connect the motor cable (1) to the machine.

3. Connect the mains connection plug (2) to a suitable power outlet or extension cable.

INFORMATION:

Protect connecting cables against heat, oil, and sharp edges.

Only use connecting cables for their intended purpose.

Do not use the connecting cable to pull the plug out of the socket.

In the event of power failures: Switch off the floor grinder and pull out the plug.

Only use approved and appropriately marked extension cables suitable for outdoors.

Avoid using extension cables with multiple sockets and the simultaneous operation of several devices.

Use extension cables that are approved for the field of application and with an adequate cable cross-section.

Recommended minimum cross-sections and max. cable lengths for 220V-240V:

Conductor cross-section mm²	Max. cable length
1.5	30 m
2.5	50 m
4.0	80 m
6.0	120 m

DANGER: Released dust particles can damage your health. Always use a dust extractor during work.

Connect a suitable dust extractor to the vacuum hose connection (13) on the grinding machine. Ensure the connection is secure. Information on connections for different TYROLIT dust extractor models can be found in their respective documentation.

INFORMATION: Always determine the grinding area when starting work. Refer to the “Floor grinding safety manual” for machine guidance and grinding techniques.

DANGER: Non-compliance carries a risk of death or severe injury.

Never work without suitable PPE.

Always wear ear protection during work.

Remove adjustment and assembly tools before switching on.

Keep children away from the work area.

Avoid working in an unnatural posture. Adjust the handle for an optimum position.

Ensure a secure footing and balance.

Avoid physical contact with earthed surfaces (pipes, heaters, etc.) to prevent electric shock.

Prerequisites:
