Porter & Cable 7800 Manual De Instrucciones página 11

1. Turn the vacuum cleaner switch ON (I). (Model 7800 only).
To reduce the risk of personal injury, ALWAYS wear a
respirator approved by NIOSH for "Dust and Mist".
2. Turn Drywall Sander switch ON (I).
3. Position the Drywall Sander lightly against the work surface. Apply just enough
pressure to align the sanding head with the work surface.
4. Apply additional pressure to engage the abrasive pad on the work surface. Move
the sander in an overlapping pattern to smooth the drywall compound down to a
"featheredge".
Apply ONLY enough pressure to keep the abrasive pad flat against the work.
Keep the sander in constant motion while the abrasive pad is in contact with the
work surface. Use a steady, sweeping motion. Excessive pressure, stopping the
sander on the work, or moving the sander erratically can cause unacceptable swirl
marks and unevenness in the work surface.
NOTE: Do not allow rotating abrasive pad to contact sharp protrusions. Contact with
protruding objects (nails, screws, electrical boxes, etc.), can severely damage the
abrasive pad.
