5.1 Changing gear
Warning
Never change gear using force and only do so when the machine is slowing
down or at a standstill.
To change into the next higher or lower gear, move the gear-change lever through an angle of approx. 50°.
If necessary (if the gear is difficult to engage), turn the drive spindle briefly by hand until the gear engages
easily.
Do not use any tools (pliers, hammer, etc.) to change gear since otherwise gear damage is a natural con-
sequence.
5.2 Safety coupling
The values set out in the table are theoretical values and may be used to provide a rough guide for gear
changing. Since a whole range of other parameters also plays a major role in adjusting the speed, we can-
not offer any guarantee if the tool is damaged when using the values in the table. Drilling work for which the
speeds are outside the range of the core drill (values printed in italics), should only be completed with ex-
treme care and by trained personnel.
5.3
Core bits
New core drill bits equipped with the hex polygon connector are already available. Adapters for continued
use of classic core drill bits are also available. Therefore existing equipment can still be used.
Only use core bits that are suitable for the type of stone.
You will keep the core drill in good condition if you only use core bits that are concentric and not deformed
ones.
Ensure that the diamond segments have an adequate undercut against the core bit body.
Warning
To use wrong tools or accessories is danger for your life.
5.4
To change a core bit
The hex polygon connection of the drill spindle allows for toolless assembly and disassembly of the core
drill bit. As soon as the drill bit is positioned on the drill spindle, both hands can be used for tightening the
safety nut on the hex polygon connector. No tools needed anytime.
