holes in the disc or its edges, and reduce the performance. If the extraction force is too low, the dust generated during operation
will stay on the material.
The tool speed and sheet grades must be selected according to the surface worked. Too high grade of the sanding sheet will
produce scratches on the surface of the material.
Higher speeds should be used for sanding ceramic materials and non-resinous wood. Resin wood should be sanded at a lower
speed. If the speed is too high, the resin in the wood will heat up quickly and the sanding sheet will be stuck in place. For a similar
reason, sanding paints and varnishes should also be carried out at a lower speeds.
Take regular breaks during operation to check the condition of the sanding sheet and the fi ll-up level of the dust extraction system.
If a sanding sheet is found to have been clogged with dust generated during operation, or that the abrasive grain has worn, replace
the sheet with a new one.
TOOL MAINTENANCE
NOTE! Before carrying out any adjustment, servicing or maintenance work, unplug the tool from the power outlet.
The Disc Head allows you to remove the disc to clean the space between the disc and the drive guard thoroughly. Hold the disc
with your hand, then use the wrench to loosen the disc retaining screw (XII). Clean the space between the disc, the disc itself and
the guard of dust and other contaminants with a soft dry cloth, a jet of compressed air at a max. pressure of 0.3 MPa, or a soft
brush. Do not use sharp objects for cleaning.
The work foot in the Delta Head cannot be removed.
After you have fi nished working the material, check the technical condition of the power tool visually and evaluate the body and
handle grips, electric cord with plug and bend protection grommet, the operation of the electric switch, the ventilation openings for
blockages, brush sparking, the noise level of bearings and gearbox, start-up and smoothness of operation. During the warranty
period, the user is not allowed to install any power tools or replace any components or parts, as this will result in the loss of war-
ranty rights. Any irregularities found during the check or the operation signal the need for repair to be done at the servicing centre.
After work has been fi nished, clean the housing, ventilation slots, switches, additional handle grip and guards using e.g. a jet of
air (pressure not more than 0.3 MPa), or a brush or dry cloth without the use of chemicals or cleaning liquids. Clean the tools and
handles with a dry, clean cloth.
