3.3 Assembling the Air-Puff Stimulus (continued)
Place the Air Reservoir near the treadmill, but out of the way (typically on the floor).
Remove and save the protective caps from the air fittings on the rear of the treadmill and the Air
Reservoir.
Using the 8’ (2.4m) air-supply line, connect one end to the 1/2" air-fitting on the rear of the treadmill.
Fully insert the 1/2" tube into the fitting, and finger-tighten the nut. Using the crescent or 1-1/4” open-
end wrench, tighten an additional 1/4 turn.
Connect the other end of the 8’ (2.4m) air-supply line to the 1/2" air-fitting on the air reservoir. Fully
insert the 1/2" tube into the fitting, then finger-tighten the nut. Using the crescent or 1-1/4” open-end
wrench, tighten an additional 1/4 turn.
Place a mark on the free end of the 20’ (6m) air-supply line 3/4" (19mm) from the end. Then, fully
insert the 1/4" tube into the 1/4" fitting on the reservoir brass tee. The mark should be flush with the
end of the fitting.
