Rear spherical wheel: OC30
Choice and maintenance (for the user)
Before starting to use the Gemini 100 steering sander it is important to
choose the spherical OC30 wheel from the OMNICASTER line to use.
The sander is provided with 2 OC30 wheels (ø35mm) with 2 different
spheres, one black and one white.
The black sphere is classed as hard due to its intrinsic characteristics as
it is made with phenolic resin.
This material is very stiff and therefore highly 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.
It is recommended for sanding hard or very hard woods.
The white sphere is classed as medium. It is made of plastic
polyurethane material with hardness of 90° Shore A ~. This material has
high elasticity properties.
The polyurethane sphere does not damage flooring, is silent, cushions
knocks and vibrations,
and the slide and capacity properties are good.
It is recommended for sanding softer woods.
.
Good wheel maintenance is important for perfect operation,
and is characterised by two phases - maintenance of the central body and maintenance of the sphere.
To clean the central body compressed air is required to remove all the sawdust from internal parts,
whereas a distinction has to be made between the two spheres for their maintenance.
The black sphere can be cleaned with a degreasing agent or alcohol.
The white sphere need only be cleaned with a damp cloth.
Check the following on both after cleaning:
-
the sphere has kept its round shape
-
the surface is not warped
-
there are no grooves
The occurrence of these phenomena could compromise the sliding action of the wheel making the tool unusable.
