Machine Control Instructions
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 (A) .
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 (B) .
To move the machine to the left, exert light downward pressure on the left handle (C) .
It is prohibited to place objects on the base frame to imitate the weight of the arms or body.

Rear Spherical Wheel: OMNICASTER
™
OC30
Choice and maintenance (for the user)
Before commencing operation of the Bona Dual Edge, it is important that you have chosen the spherical OC30 wheel from the OMNICASTER ™ line. The sander is provided with two OC30 black wheels (Ø 35mm).
The glossy sphere is recommended for use on hard or very hard woods.
The material (phenolic resin) is hard, resistant to abrasion and not affected by external contamination from liquids, dust, gels, etc. The sphere is silent and its slide and capacity properties are excellent.
The mat sphere is recommended for use on softer woods.
The material (plastic polyurethane) has high elasticity properties with a hardness of 90° Shore A ~.
It softens vibrations and will not damage flooring. The sphere is silent and its slide and capacity properties are good.
Proper wheel maintenance is important for perfect operation. Maintain both the central body and the sphere. To clean the central body use compressed air to remove dust from internal parts. The glossy sphere can be cleaned with a degreasing agent or alcohol, whereas the mat sphere can be cleaned with only a damp cloth. After cleaning be sure the sphere has kept its round shape, is not warped, and has no grooves. Occurrence of these phenomena could compromise the sliding action of the wheel, making the tool unusable.
