a. Confirm the speed sensor is positioned properly and the hardware is fully tightened.The speed sensor
magnet on the drive pulley (reference 2) should be centered on the speed sensor if it is positioned correctly.If
the speed sensor is not centered, refer to the "Replace the Speed Sensor Assembly" section of the service
manual to adjust the speed sensor position (reference 2).You will need a5mm Allen wrench and a 10mm
open-ended wrench to adjust the speed sensor hardware.
b. Confirm the speed sensor and speed sensor wire are undamaged.Inspect the speed sensor for damage,
then follow the cable from the speed sensor to its connection on the MCB (reference 3). Check for any crimps,
cuts, or fraying along the length of the wire.If the speed sensor or wire is damaged,order a Speed
Sensor[13662.A].
c. Confirm the speed sensor is securely plugged into the MCB. Unplug the speed sensor cable from the MCB
and firmly reconnect it (reference 3).
d. Once all steps are complete, plug your machine back into power and test if the issue persists [13662.B].
4. If the issue persists, order a Speed Sensor[13662.C].

The speed sensor magnet is a small magnetic disc on the side of the drive pulley (labeled in left image).
If adjustments are needed, use a 5mm Allen wrench on the outside of the frame (left image, black circle) and a 10mm wrench on the inside
of the frame (right image, white circle) to adjust the speed sensor mounting hardware.
