OPERATING INSTRUCTIONS
FUNCTIONAL DESCRIPTION
The Porter-Cable Drywall Sander is designed for sanding walls and ceilings
made of drywall or plaster. The Sander provides a superior finish, and is faster
than conventional finishing methods for both new construction and renovation
work. Clean-up time for Model 7800 is minimized by the use of an external
vacuum cleaner attached to the sander.
ABRASIVE DISC SELECTION
The Drywall Sander is shipped with a 100 grit, abrasive disc installed. This
abrasive is suitable for most applications. Abrasive discs of 120 grit and 150
grit are available for situations requiring a smoother finish.
CAUTION: Do not attempt to use any abrasives other than those
recommended by Porter-Cable.
HOW TO HOLD A
DRYWALL SANDER
The Drywall Sander should be held
with both hands on the main tube (A)
Fig. 1. The hands may be positioned
anywhere along the main tube to
provide the best combination of reach
and leverage for the particular
application.
CAUTION: Keep your hands on the
main tube (A) Fig. 1. Keep away
from the sanding head area. The
sanding head swivels in multiple
directions and could pinch your
hand.
