Wheel Drive Components — The wheel drive motor
bearings are pre-lubricated and no further lubrication is neces-
sary. Make certain air cooling ports are not blocked.
The wheel drive a pulley is secured to the drive motor shaft
by a setscrew. The setscrew is secured with removable adhe-
sive to prevent loosening. Annually confirm setscrew is secure.
The wheel drive belt is a urethane stretch belt designed to
provide constant tension through the life of the belt. No adjust-
ment is required. Inspect the drive belt annually for proper
tracking and tension. A properly tensioned belt will turn
the wheel immediately after power is applied with no visible
slippage during start-up.
