    Operation Manual

    Please read this entire document prior to operating the miter gearbox. Miter gearbox failure or injury

    to operators may be caused by improper installation, operation or maintenance.

    Installation

    Miter gearboxs must be mounted on a rigid, structurally sound baseplate. Ensure that miter gearbox

    mounting pads rest evenly on the baseplate. The use of shims may be required to avoid housing

    distortion which could alter the gear mesh or cause premature bearing failure.

    The miter gearbox may be driven by direct coupling, flexible coupling, or V-belt drive. Couplers

    should require only a light force to install. The driveline must be accurately aligned within the

    equipment manufacturer's requirements to limit operating loads and minimize thrust loads on the

    miter gearbox shaft. V-belt drives must be mounted close to the housing to minimize excessive

    overhung loading which could result in early bearing or shaft failures. Sheaves must fit correctly. At

    installation, a tight forced fit could move the shaft from its normal position and cause internal damage.A loose fit could induce excessive vibration during operation and cause shaft damage or breakage.

    Warning

    When mounting the miter gearbox, the buyer is responsible to properly determine the quality or grade

    of fastener, thread engagement, load carrying capacity, and torque requirements.

    Warning

    The buyer is responsible to provide protective shields over all external rotating parts, couplers, or

    shaft extensions mounted on or with the miter gearbox. Protective clothing must be worn when

    installing or maintaining the miter gearbox and operating system.

    Initial operation should be carried out under no-load conditions. Before applying power to the miter

    gearbox installation, review the following:

    1. Check tightness of mounting bolts.

    2. Check for proper oil level in miter gearbox.

    3. Be certain that tools, debris, etc., are clear from rotating parts.

    4. Rotate shafts by hand. If they do not rotate freely, check for uneven mounting, coupling

    misalignment or excessive belt tension.

    If all tests are satisfactory, make connections to shafts, ensure that all safety devices are in place,

    and begin operation.

    LubricationAll miter gearboxes are factory tested prior to shipment. They include the correct amount of oil unless

    specified by the customer to be shipped dry. Shaft bearings a
