tube are removed, the operator can be pried out.
the new operator into the channel. Turn the handle counter-clockwise as far as
it will go. Insert the torque tube with its torque arms rotated fully upward.
Be sure the same end of the tube goes into the operator. Raise the opposite end of the tube high
enough to slip on the bushing. Lower the bushing and tube into place and align
the holes. Resecure the operator either
with pop rivets or small machine screws, star
washers and nuts. Use the same
technique on the bushing. Reattach the
torque arms to the link arms and slide the E rings into place. Slide the knob onto the operator shaft and

notches in the tube ends. As necessary, rotate the operator shaft and move the
vents so that the torque tubes fit snugly into the operator sides. Press
downward on the operator to reset it in the center of the windowsill. Align the
mounting holes and replace the screws, thereby securing the operator into
place. Slide the crank onto the operator shaft and open and close the vents to
check for smooth operation. If satisfactory,
replace the screen, operator crank and screw.

and torque arm assembly from the operator.
Remove the screws holding the operator in place. Pry the operator out of
the channel and remove it.
INSTALLATION: Using the operator knob, turn the operator shaft fully
counterclockwise. Slide it into the channel and align the holes. Screw the
operator into place using the screws provided. Rotate the torque tube assembly
so that it fits snugly into the operator. Place the bushing onto the opposite
end and slide it up into place under the mullion. Align the holes of the
bushing and frame. Reinstall the bushing using the screws provided. Attach the
torque arms to the link arms and secure them with the E rings. Slide the knob
onto the operator shaft. Open and close the vent to check for smooth operation.
If satisfactory, snap the screen into place. Install the operator knob onto the
