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. Align notch on damper ring
with locating tab on shroud and depress ring
with thumbs until shroud seats into groove
completely around ring (Fig. 4).
Re-attach backing pad as described in
"Backing Pad Installation"
IMPORTANT: Ring should not have bends or
ripples when correctly seated.
