6. There are two methods for checking belt tension.
You can use whichever method you prefer, but do
not use the chair position from one method with the
measurement range from the other method.
Use Method 1 (below, left) if the chair is laying on its
tracks on a workbench. Use Method 2 (below, right) if
the chair is standing on its wheels.
Method 1
Chair MUsT bE layinG On iTs TraCks
On a WOrkbEnCh
Grasp the belt at the track midpoint and pull the belt
away from the track to remove any slack, then measure
the distance between the exposed surface of the track
and the inner surface of the belt. Take the measurement
at the track midpoint.
The belt is correctly tensioned when the measurement
from the exposed surface of the track to the inner
surface of the belt is 1-1/4 in. to 1-1/2 in. (31.75 mm to
38 mm), as shown in Figure 34.

7. It may be necessary to repeat the tensioning and
measuring one or more times to achieve the correct
belt tension.
8. When the belt tension is correct, finish tightening the
bolt and nut to maintain the tension.
9. Repeat Steps 3-7 to adjust the tension of the other
track belt.
Method 2

Grasp the belt at the track midpoint and pull the belt
away from the track to remove any slack, then measure
the distance between the exposed surface of the track
and the inner surface of the belt. Take the measurement
at the track midpoint.
The belt is correctly tensioned when the measurement
from the exposed surface of the track to the inner
surface of the belt is 3/4 in. to 1 in. (19 mm to 25 mm)
as in Figure 35.
