1. Remove the Top Shroud, Left Shroud and Right Shroud
from the Main Unit. Refer to the “Replace the Shrouds”
procedure.
2. To test the Drive Belt tension:
• Push the Drive Belt downward at the midpoint (M)
between the pulleys and measure the distance. The
Drive Belt should have only 0.25” (0.64 cm) of give. See
Figure 1.
Or:
• Hold the edges of the Drive Belt at the midpoint (M) and
twist it (see Figure 2). It should turn only 90 degrees
(1/4 turn, to vertical).
If the tension is correct, go to Step 6.
If the tension is too loose or too tight, adjust the position of the
Flywheel. Continue to Step 3.
!
Disconnect all power to the machine before you service it.
NOTICE: It is necessary to remove the Shrouds for this procedure. Refer to the “Replace the Shrouds” procedure.
