Maintenance And Cleaning - Mestra R-080080 Manual Del Usuario

5. Apply the M24 spanner (also supplied with the unit) to the two grooves in the plate
neck.Turn it anticlockwise to free the thread. At the same time ensure that the socket
wrench properly locks the motor shaft. If there is strong resistance, use a nylon
hammer very lightly on the end of the spanner. Perform this last operation with
extreme care, since otherwise the motor shaft could be damaged or put out of
balance.
6. Fit the new disc, being especially careful not to damage the coupler shaft stop. Rotate
it manually to check that it is free, and that there is no significant warping.
7. Fit the housing and retighten its four lock nuts. We recommend that loosening oil be
applied to all threaded connections a few minutes before an abrasive disc is changed.

MAINTENANCE AND CLEANING

To ensure correct, reliable, and enduring operation, we recommend:
• After use, clean dust and plaster from the support surface (B) and from the front
fairing (D).
• For general cleaning, use a cloth dampened in soapy water. Do not use alcohol,
solvents, or other liquids.
• Never immerse the unit in liquid.
• If you notice unusual vibration or noise, send the unit to a technical assistance centre.
• Change the abrasive disc when you notice a significant fall in performance.
• After changing the disc, check that there are no unusual vibrations.
• The unit was designed to endure sound operation when it rests on the four suction
cups at the base. These are sufficient by themselves to withstand the force applied in
facing.
• To ensure optimum performance, Talleres Mestraitua, S.L. recommends the use of
the MESTRA R-080086 catch basin, wich is designed specifically for R-080080, R-
080081, R-080082 and R-080083 cutters.
PRECAUTIONS
♦ Before connecting the unit to the power supply, make sure the voltage is correct (230
V, 50/60 Hz with earth).
♦ Whenever you are carrying out a cut, protect yourself suitably. Use gloves, safety
goggles, and mask.
♦ Always use suction (only in the case of R-080084). In the case of cutters R-080080
and R-08001, always use the system with disc-cleaning by water.
♦ Do not allow children or unspecialised personnel to operate the unit.
♦ If the motor shaft jams during normal operation, disconnect the unit from the power
supply before endeavouring to unlock the shaft by forcing its rotation manually.
♦ Do not polish, brush, or grind materials that could release particles that are toxic
when inhaled.
♦ Before using the unit, make sure it is seated on a firm and solid base.
♦ Do not use the unit close to solvents or other inflammable materials.
♦ After changing the disc, make sure that the gasket belonging to the motor disc-shaft
plate coupling is leak-proof. Similarly check the entire disc-flushing system.
♦ When installing the unit, make sure that the disc-cleaning circuit is perfectly leak-
proof.
