INSTALLATION
Holding belt with tabs to the outside push
end tab through two links (three links for
wedge profiles). Twist tab 90° into place.
9
With your thumb twist second tab 90°.
Push belt end down over tab with your
opposite hand. For wedge profiles,
repeat with remaining tab.
Ensure all tabs are fully turned and
across the belt.
Rotate assembled belt so tabs are inside
(facing down into the pulley groove).
Note:
If take-up system is not available, links can be added to reduce the
tension. If links are added the belt may have to be re-tensioned by
removing the extra links between ½ hour and 24 hours running at
full load.

FORCE DEFLECTION GUIDELINES
Note:
If deflection force drops below specified force for Operation, remove links
or adjust take-up until belt is back to Installation force.
12
Determine direction of drive rotation. Belt
must travel in the same direction as the
direction arrow. Tabs will trail.
13 A: DRIVE
13 B: WEDGE
Fit the belt in the closest groove of
the smaller pulley. Roll belt onto larger
pulley by turning the drive slowly. The
belt should feel tight. DO NOT JOG THE
MOTOR. Once installed check to make
sure the all tabs are in position and
the belt is not twisted. For multiple belt
drives, work belt from groove to groove.
If the installation with the recommended
# of links removed is too difficult see 13B
Use the belt take up system to install to
the proper tension: position the motor
approximately in the middle of its range
of travel (mark position), hand fit the belt
removing the recommend # of links.
Move motor forward reducing the center
distance enabling easy installation of the
belt(s). Return motor back to original
marked position.
