measure and adjust the track-belt tension, according to
the instructions on page 27.

For Method 1:
Open the track system and lay the chair
on its tracks on a workbench as shown in Figure 31.
For Method 2:
Stand the chair on its wheels on a
workbench, then open the track system and engage
both wheel locks.
3. Loosen the bolt and black cap locking nut located at
the top end of the track (Figure 32).
4. Slide the #4 Phillips screwdriver into the adjustment
slot (Figure 32).
5. While one person tensions the belt by using the #4
Phillips screwdriver to pull the belt roller toward the
top of the track, the other person uses the two 7/16-
inch wrenches to tighten the bolt and nut only enough
to hold the tension (Figure 33).
