Operation
Startup Procedure
1. By hand, turn wheel clockwise (as viewed
from the pulley side), to verify wheel turns
freely through 360º rotation.
2. Before applying power to drive motor,
confirm wheel segments are fully engaged in
wheel frame and segment retainers are
completely
fastened.
(See
Segment
Installation Diagram).
3. With hands and objects away from
moving parts, activate unit and confirm
wheel rotation. Wheel rotates clockwise (as
viewed from the pulley side).
4. If wheel has difficulty starting, turn power
off and inspect for excessive interference
between the wheel surface and each of the
four (4) diameter seals. To correct, loosen
diameter seal adjusting screws and back
adjustable diameter seals away from surface
of wheel, apply power to confirm wheel is
free to rotate, then re-adjust and tighten hub
and diameter seals, as shown in hub seal
adjustment diagram.
5. Start and stop wheel several times to
confirm seal adjustment and to confirm belt
is
tracking
properly
on
wheel
rim
(approximately 1/4” from outer edge of
rim).
