1. Never mount tools other than XEBEC Brush Surface.
This product is an optional tool exclusively equipped to be used for the XEBEC Brush ™ Surface. There is the risk ofdamaging the main body and machine and/or sustaining an injury if furnished with a tool other than for use with the
XEBEC Brush ™ Surface because of inability to withstand the load.
2. Never use at a rotation speed exceeding the maximum rotation speed.
The maximum rotation speed of this product varies by the brush size being used (XP-AUT06M: MAX10000min-1, XPAUT15M: MAX6000min-1). Using at or higher than the maximum rotation speed may result in breakage of the tool andmachine and/or sustain an injury.
3. Never use this product with the shank not fully inserted all the way to the end of the chuck when mounting itto the machinery.
There is the risk of breaking and rupturing the shank section, damaging the machine, jigs, and work-pieces and/or
sustaining an injury.
4. Tighten the setscrew at the flat section of the shank when fastening with the side-lock style.
Tightening it at any place other than the flat section is dangerous, as the sleeve may be disengaged from the machine,
damaging the machine, jigs and work-pieces and/or sustaining an injury.
5. Never use any brush other than XEBEC Brush SurfaceTM that matches with the main body size.
It is dangerous since the brush may be disengaged from the main body, damaging the machine, jigs and work-pieces.
6. Conduct a trial run for one minute or more before starting work, and three minutes or more after changing
the machine and/or replacing the tool. Immediately stop the operation with any sign of abnormality such as
looseness in the mounting section of machinery or tools, or vibration.
When the use continues, there is the risk of damaging the machine, jigs and work-pieces, and/or sustaining an injury
