Adjusting Belt Tension
Adjusting the belt tension is a two-person
operation.
TENSION-ADJUSTMENT
1. Decide if you will use Method 1 or Method 2 to measure and
adjust the track-belt tension.
2. For Method 1: Open the track system and lay the chair on its tracks
on a workbench (Figure 35).
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 36).
4. Slide the #4 Phillips screwdriver into the adjustment slot (Figure 36).
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 37).
