Different floors and different tools require different loads on the grinding discs. By shifting
the rear wheel axis, this load can be altered. When the axis is fixed in the rear position, this
allows the maximum load on the tools. The more forward position means less load. The
rear wheel axis can be comfortably moved by loosening the two screws behind the rear
wheels.
5.4 Belt tension
Loosen the four fixing screws of the motor. To do this you must remove the front belt cover
and the cover behind the Spindle. By turning an M10 Nut on the rear side of the belt
tensioner (metal plate underneath the motor Appendix diagram No. 101) the tension of the
belt can be adjusted. The tooth belt of the DELTA II should be able to move halve a
centimetre forwards and backwards half way between the pulley and the motor shaft.
Attention: Before working on the grinder bring the motor to a total stand still and
disconnect from the power supply.
Attention: Tools can be hot after use.
- Tilt the machine onto the back wheels and rest it on the bar underneath the control
panel.
- All brackets for segment plates (Appendix diagram No. 11) are secured to the tool
brackets (Appendix diagram No. 3) by 3 Allen screws.
- By loosening the screws the discs can be removed.
- Check the grinding tool for wear or damage ready for the next application.
- Fix new tools according to the appendix „Tools“.
