Installing the Sanding Bumper
The sanding bumper is used to help keep the sander from
gouging perpendicular borders around the sanding area. It
can be removed from the sander for better visibility of the
sanding disk for most operations.
To install the bumper, slide it over the front of the sander’s
housing until the tabs lock into place.
To remove the bumper, pry out on the end of the bumper
to release the tabs and slide the bumper off the sander
housing.
Setting the Sanding Mode
The Rotex sanders can be switched between gear-driven
(Rotex) mode and random orbit mode. The RO-90 has the
third option of orbital mode (Delta). The chosen mode is
dependant on the type of sanding required.
Rotex mode is the most aggressive for rapid material
removal. Random orbit mode produces the finest finish with
minimal visible scratches. Orbital mode is typically used in
conjunction with the delta sanding pad for detail sanding,
but may also be used with circular sanding pads if desired.
Changing modes should be done with the sander turned
off. For the RO-125 and RO-150 sanders, slide the selector
switch side to side to the respective mode setting. For the
RO-90, rotate the selector dial to the desired setting.
NOTICE: The RO90’s mode selection dial has an
interlock to prevent the sander from being oper-
ated in either of the rotary modes when the DX pad
is installed. Forcing the dial to turn with a DX pad
installed will damage the sander.
Turning on the Sander
For best control and sanding results, the sander should be
placed on the sanding surface with no downward pressure
before turning it on, and lifted from the surface before
turning it off. The Rotex sanders have soft-start circuitry, so
there will be a slight delay before the sander reaches the set
motor speed.
To turn the sander on, slide the power switch forward until
it clicks into the on position. To turn the sander off, slide the
power switch back.
