• T27 Torx.
• Wire Cutters.
• 1/2” Open End Wrench.
• 7/64” Allen Wrench.
PROCEDURE
1. Unplug the bed power cord from the wall socket.
2. Manually raise the fowler to 60 degrees.
3. Using a 7/64” Allen wrench, loosen the screw holding the linkage to the potentiometer shaft and remove the linkage
from the shaft.
4. Using a ½” open end wrench, remove the nut holding the potentiometer to the frame and disconnect from the 3
pin quick disconnect.
5. Install the fowler potentiometer to the Fowler platform arm using a ½” combination wrench, making sure to align
the potentiometer alignment tab up with the notch in the fowler frame.
6. Using a multi-meter and small flat blade screwdriver, set the fowler potentiometer to 500 +/-50 ohms, using the
black and white wires from the fowler potentiometer.
7. Using a 7/64” Allen wrench, tighten the set screw on the fowler potentiometer linkage attaching to the potentiometer.
Make sure to double check the ohms reading after tightening the set screw; readjustment maybe necessary.
