TRACK BELT RECONDITIONING

Tools Required:
• (2) 7/16" Wrenches
• Permanent Marker
• 50 Grit Sandpaper
• Sanding Block
Procedure:
1. Extend the upper control handle, open the Stair-TREAD™
system tracks and tip the chair forward until it rests on
the handle and the seat section as shown in Figure 42.
2. Using two 7/16" wrenches, remove the hex head bolt,
hex nut, two washers, spacer and wheel from both sides
of the track frame. Remove the wheel and spacer down
in the direction of the floor.
3. Turn both belts over so the small internal teeth are on
the outside. Put the belts on the track frame for support
while sanding them.
Note: New track belts must be installed if the inner
cords are exposed on the wear surfaces.
4. For a start/end point reference while sanding, use a
permanent marker to color a tooth on the belt.
