Swing Arm
The Swing Arm holds the main Tire Changer Tool, the Mount/Demount Head. It swings out of the way
when you do not need it.
Front view. Swing Arm shown fully to the right. Not necessarily to scale. Not all components shown.
The main parts of the Swing Arm are:
•
Swing Arm
. When facing forward, puts the Mount/Demount Head directly over the middle of the
Turntable. From that position, the Swing Arm can swing up to 90° to the right, which lets you get it
out of the way when desired.
• Swing Control . Limits how far the Swing Arm can move. Makes sure the Mount/Demount Head
cannot go past a point you control. Useful if you are going to be working on multiple Wheels that
are exactly the same size; move the Mount/Demount Head to the desired location, then adjust the
Swing Control so that the Swing Arm will return to this same position if moved out and then back.
•
Mount/Demount Head
. Attaches to the Bottom of the Shaft. The entire purpose of the Swing
Arm is to let you get the Mount/Demount Head to where you need it.
•
Shaft
. Moves the Mount/Demount Head up and down. Grab the Mount/Demount Head to move
the Shaft up and down. Do not grab the Shaft, it is greased.
• Shaft Lock Handle . Locks the Shaft in position when you get it to the right height. Locking the
Shaft moves it a very small amount up.
• Shaft Spring . Pushes the Shaft and the Mount/Demount Head back up when you release the
Shaft Lock Handle.
• Moving the Swing Arm . Grab the end of the Swing Arm below the Shaft Lock Handle and
above the Shaft to move the Swing Arm (location shown in the drawing above). Do not grab the
Shaft itself, as it is greased.
