14.To set drive belt tension, turn adjustment screws (J) equally on both the upper and lower tension assemblies. Turn the screws counterclockwise to increase tension or clockwise to decrease tension. See Figure 4-3.

Use a force gauge to pull the belt outward 25 mm [1 in] at midspan, as shown in Figure 4-4 with a moderate pulling force of 3.5 kg [7 lbs].

15.After adjusting belt tension, tighten lock nuts (H) on both the upper and lower tension assemblies.
