Manufacture Tech Note: Proper Installation of an Operator Cover & Nested Folding Handle.
When installing the cover and handle on the operator you should follow these
• Snap the cover onto the operator base.
• Place the handle onto the spline of the operator and rotate the handle to close
• Lock the window in place.
• Rotate the handle Ľ turn back (towards opening direction) to reduce the
pressure on the operator.
• If the handle needs to be positioned in a nested cover you can remove the
handle at this time and re-position it so that it will rest correctly in the nested
• Tighten the set screw on the handle.
• Unlock the window and cycle the sash open and closed until the handle returns
to the starting position whereby there is no additional torque required to close the sash. Note: the sash should travel to a point that the lock can easily engage
and seal the window.
• If the window does not come all the way into the closed position, and more force
is required on the operator to close the window, you will need to review the
window for the following; sash sag; racked window; lock points that are not
properly aligned; or hinges not installed correctly. These issues should be
corrected prior to repeating the installation of the handle onto the operator
Placing the operator and the handle under high stress and abusive loads can cause
permanent failures to the handle or operator as the window is repeatedly opened and
