B. Agitator/brushroll Jam Light Comes On Too Soon or Not At All
If the sensor is coming on too soon, the customer may be vacuuming one extra plush carpet. Set the height adjustment to higher level and
retest. If the sensor still comes on too soon, it may be out of calibration and need adjusting. - See Adjusting the Agitator/brushroll Jam
Indicator below.
If sensor is coming on too late or not at all the sensor may be out of calibration and need adjustment. - See Adjusting the Agitator/brushroll
Jam Indicator below.
Adjusting the Agitator/brushroll Jam Indicator:
1. Unplug the power cord, remove the dust cover, and lower the upper body to the reclined position.
2. Locate the two plugs on the right side of the motor cover. (See Figure M. Agitator/brushroll Jam Screw - Full Bag Screw Position)
3. Remove the right plug from the motor cover. A gray colored airow adjustment screw should be visible through the hole.
4. The slot of the screw should be in the “Eleven o’clock” position. If not, adjust it to the “Eleven o’clock” position using a small at-headed
screwdriver that ts through the hole.
NOTE: Be careful not to apply pressure while making the adjustment.
5. Reassemble the vacuum and retest it to ensure it is operating properly. Follow testing procedure in Section III.Troubleshooting: G. Agita-
tor/brushroll Jam Test
6. If the problem still exists, or if the screw is already adjusted to “Eleven o’clock”, make gradual adjustments (approximately “one hour”
increments or less). Turn the adjustment screw counter-clockwise to make it less sensitive (harder to jam) and clockwise to make it more
sensitive (easier to jam). It is important to make small adjustments and test the vacuum after each adjustment.
