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 OMNICASTERTM 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 a ected by external
contamination from liquids, dust, gels, etc. The sphere is silent and its slide and capacity
properties are excellent.en.
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.
