    ! WARNING

    Rotating Components!

    Failure to disconnect power before servicing could result in rotating components cutting and slashing technician which could result in death or serious injury.

    Disconnect all electric power, including remote disconnects before servicing. Follow proper lockout/tagout procedures to ensure the power can not be inadvertently energized.

    The fan belts must be inspected periodically to assure proper unit operation. Replacement is necessary if the belts appear frayed or worn. Units with dual belts require a matched set of belts to ensure equal belt length.

    When removing or installing the new belts, do not stretch them over the sheaves. Loosen the belts using the belt tension adjustment bolts on the motor mounting base.

    Once the new belts are installed, using a Browning or Gates tension gauge (or equivalent) illustrated in Figure 14; adjust the belt tension as follows:
