BACKING PAD DAMPER
Your tool is equipped with an integrated
backing pad damper ring. This damper
reduces the no-load speed, which helps
prevent swirl marks on the workpiece surface
and provides uniform finishing.
NOTE: If you notice steadily increasing no-
load speed, this indicates that the damper ring
is worn and needs to be replaced.
To replace damper ring, remove backing pad
as described in "Backing Pad Installation" and
remove worn damper ring by pulling firmly out
of locating groove. Loosen the two screws on
shroud just enough so you can separate
shroud approximately 1/4 inch. Align locating
bumps on damper ring with cut outs in shroud
and depress ring with thumbs until shroud
seats into groove completely around ring, then
tighten screws (Fig. 5).
Re-attach backing pad as described in
"Backing Pad Installation"
