6 a. Adjusting the Motor Belt Tension
NOTE: The motor belt tension need not be tightened as
tightly as the main timing belt (see 6 c.)
Check the belt tension for tautness by pressing it with the
index finger (see Figure 6.1). Proper belt tension provides
for some belt flexibility under light finger pressure, but
should not be so tight as to bind the machine. If a correction
is necessary:
•
Loosen the motor frame screws 1, 2, 3, and 4 shown in
Figure 6.2, and slide the motor frame up or down to
achieve the correct adjustment.
