It is prohibited to place objects on the base frame to imitate the weight of the arms or body.
The Bona Dual Edge is defined as a steering sander due to its innovative control characteristics (patent pending). The point of pressure is related
to the chosen direction whereby the pressure exerted on one side moves the machine in the same direction. Therefore, the machine moves left
and right on the basis of the force and pressure applied to the handles.
Until now all small disc sanders have required point pressure (i.e. a load perpendicular to the center of the machine), whereas the Bona Dual
Edge steering sander has two counter-rotating discs. The thrust of the left disc is counterbalanced by the thrust in the opposite direction exerted
by the right disc

The correct operator position for optimum control is behind the
machine and not at the side, with one hand on each handle. Once
the machine has been started it can be noted that it remains quite
stationary even though the discs in contact with the floor are turning.
To move the machine to the right, exert light
downward pressure on the right handle

To move the machine to the left, exert light
downward pressure on the left handle
