Help, My Dyson Won't Stand Up!
During shipping, moving parts on a Dyson vacuum can shift in position. One of these parts is a swinging arm in the base of the unit. This arm holds a removable elbow pipe in the vacuum's air passage. This arm can move out of the way so that you can clear out a blockage in the air passage. When this arm is out of position, the vacuum will not lock in the upright position. Fig. 1 Shows the base of a Dyson DC14 Animal locked upright. The red arrow points to the swinging arm. Fig. 2 shows the vacuum with the swing arm out of position. Since the swing arm is lower than it should be, it doesn't line up with the tab on the main body indicated by the red arrow.
Lean the handle of your Dyson all the way back and locate the black button on the right side of the vacuum indicated by the red arrow in Fig. 3.. Press the button down and hold it to unlock the swing arm.
While holding down the black button, pull the swinging arm (Shaded red in Fig. 4) all the way up. Fig. 5 shows the swinging arm in the correct position. Release the black button to lock the swing arm back in place.
The vacuum can now lock in the upright position as shown in Fig. 6. Note how the tab on the swinging arm overlaps the tab on the main body.
