Bona Dual Edge Manual

EN
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

Machine Control Instructions
It is prohibited to place objects on the base frame to imitate the
weight of the arms or body.
