Follow the instructions below to set the motor
belt tension.
a. Adjust the skew motor on the bracket to

b. Using a scribe, mark the resting location of
the belt against the reflector midway between
the hub and the pulley (see
c. Using a scribe and ruler, measure 1/8"
outward from the scribe mark you just
created (see Figure
desired belt deflection distance.
d. Using the supplied tension meter, secure the
belt at the midway point. Then pull the belt
outward using 2 lbs of force (see
e. Reference the scribe marks in relation to the
belt position. Adjust the motor position, as
required, to ensure the belt deflection is 1/8"
using 2 lbs of force.
f. Using a 2.5 mm ball-end hex wrench, fully
tighten the four motor screws (see
