use damaged, out-of-centre or vibrating grinding tools.
Damaged grinding tools can burst and cause injuries.
Operate the power tool with both hands.
Switch the power tool ON when holding it above the
surface to be grinded. Let the diamond grinding tool reach
is maximum no-load speed before it makes contact with
the surface.
Make sure the diamond grinding tool is rotating in the cor-
rect direction. Verify the direction of the arrow on the dia-
mond grinding tool is corresponding the direction of the
arrow on the power tool.
Clean the grinder spindle and all parts to be mounted
before you start. Verify the condition of the fl anges and
diamond grinding tool. The supporting surfaces between
the fl anges and the diamond grinding tool must be clean
