line connections.
Have an electrician or qualified service person check
all hook-ups including all outboard wiring.
Have a qualified service person adjust the yellow UP
limit switch. Deploy screen and turn the adjusting
screw (yellow) clockwise.
Motors require full voltage. Have an electrician or
qualified service person check available voltage.

Allow the motor to cool down. Complete cooling can
take up to an hour. Heat gain is cumulative and
takes time to dissipate. If motor use is initiated before
it has cooled completely, the motor will shut down
again when it reaches maximum temperature.
Brush off or use a mild detergent solution with clean
rag or cotton swab.
Check back of screen; gently brush debris away by
hand.
