5 Safety rules for the operation of the OMEGA floor grinder
Intended application and operation:
Grinding of flat, horizontal, dry surfaces that are typically concrete, asphalt or steel and with
or without a coating. For optimum performance and compatibility always use tools supplied
by CONTEC. Operation of the grinder outdoors is only permitted if the weather is dry.
Attention ! The OMEGA floor grinders are constructed according to existing safety rules
and regulations. These technical precautions must not be removed or changed
under any circumstances. While operating the grinder the following points
should also be kept in mind:
1. The floor grinder may only be operated by trained professionals. The operators have read
and be familiar the contents of this manual.
2. The floor grinder must not be operated in areas where the hazard of explosion or fire
exists.
3. The floor grinder can only be started when the tools are not in contact with the floor. Do
always start the machine in a tipped position.
4. The tools and discs may be hot after use. Take care when changing them.
5. Never operate the floor grinder on a sloping surface.
6. Take care when moving the machine on a sloping surface, substantial rolling forces can be
produced.
7. The machine should always be stored in a warm, dry place when not in use.
8. The floor grinder may only be operated with the dust guard (Appendix diagram No.3).
9. Only CONTEC original tools and spare parts are to be used.
10. The grinder should only be operated with all safety guards in position.
11. When changing tools, during transportation, cleaning, repair or maintenance the grinder
must be disconnected from the mains.
12. The operator must never leave the machine unattended during operation.
13. Before leaving the machine all rotary parts must be brought to a standstill. Electric models
must be disconnected from the power supply. Ensure the machine cannot roll or move by
itself.

14. After any maintenance and adjustment all safety guards must be refitted.
15. Ear protectors must be worn.
16. Eye protectors must be worn.
17. Safety shoes with steel caps must be worn.
18. When operating the grinder produces large volumes of dust the grinder should be
connected to a suitable dust collector.
19. Depending on the floor (floor coating) grinding can produce gases. The operator must be
held responsible if the gases generated are hazardous and whether protection is necessary.
Grinding floors containing asbestos is especially dangerous and can cause health
problems. Special masks must be worn which keep the breathing air clean. A dust
collector must be used and should be equipped with filters suitable for asbestos dust.
20. The floor must be brushed before grinding to prevent loose material collecting in the tools
and then being thrown out with force. Anchor screws and bolts in the floor can also be
seen better if the area is clean. If the grinding head strikes an anchor screw or bolt then
serious damage can be caused to the machine and grinding head.
6 Operating
After mounting the appropriate tools, the operation of the OMEGA grinder can begin.
Connect the hose of the dust collector to the hose port of the grinder.
Adjust the grinder by turning the hand wheel of the height adjustment (see diagram No.
35/36) so that the motor axis is 90° level to the floor. Lift the tool from the floor by tilting the
machine onto it's back wheels. Switch the motor on.
Attention ! When switching on the motor the machine jumps slightly.
After the motor has reached full rotation place the tools carefully on to the floor. If the
machine is correctly adjusted (see above) it is easier to move across the floor. If the machine
pulls to the left or right, the machine has to be re-adjusted with the hand wheel of the height
adjustment.
Attention ! Never switch the motor on while the tools still touch the floor.

7 Changing and replacing of the tools
Attention ! Before working on the grinder allow the motor to come to a complete stand still
and disconnect from the mains.
-Tilt the machine onto the back wheels and rest it on the handlebar.
-All tools are fixed with 3 screws on the tool bracket.
-Loosen and remove the screws with a 6 mm Alan key.
-Check the grinding tool for wear and tear for the next application.
-Fix a new tool with the 3 screws on the tool bracket.
-Adjust the different heights of the tools with the hand wheel of the height adjustment. The
motor axis of the grinder has to be 90° level to the floor.
-Different tools need different heights for the rubber sealing around the discs.
