    PPLY THE ADS TO A Powering up the Lifter Place the lifter's power switch in the “on” ( ) position. The blue power light remains illuminated while the lifter is powered up. Keep the power switch in the “on” position while lifting a load.

  • Page 19: Sealing The Pads Against The Load

    Sealing the Pads against the Load The apply/release switch is located on the movable control pendant. The movable control pendant allows the vacuum controls to be moved away from the lifter, so that the operator can control airflow at a distance equal to the length of the extension cord. W AR NI NG: Do not disconnect control pendant during lifter operation.

  • Page 20: Vacuum Level On Optimal Surfaces

    Vacuum Level on Optimal Surfaces When the lifter is attached to clean, smooth, nonporous load surfaces, it should be able to maintain a vacuum level in the green range on the vacuum gauge, except when used at high elevations (see SPECIFICATIONS: Operating Elevation). If not, make sure the vacuum switch is adjusted correctly (see MAINTENANCE: V ).

  • Page 21: T O Lift And Move The Load

    IFT AND OVE THE About the Tilt Linkage W AR NI NG: M ak e sure load is positioned correctly on lifter; unbalanced loads m ay tilt unexpectedly. The lifter’s tilt linkage is designed to automatically hold a balanced load in either the upright or the flat position.

  • Page 22: Load Capacity And The Lift Light

    Load Capacity and the Lift Light A lifter’s Load Capacity is rated at a vacuum level of 16" Hg [-54 kPa] (see SPECIFICATIONS). After the lifter has attained this level, the vacuum pumps turn off automatically, to conserve battery energy. At the same time, the green vacuum lift light turns on, to indicate that the lifter is ready to lift the maximum load weight.

  • Page 23: Controlling The Lifter And Load

    W AR NI NG: Stay clear of any suspended load w hile alarm is sounding. Discontinue lifter use until the cause of the vacuum loss can be determined. Using the lifter on contaminated, rough or porous surfaces may result in a vacuum loss, due to leakage between the vacuum pads and the load.

  • Page 24: T O Tilt The Load

    ILT THE W AR NI NG: Alw ays keep hands and fingers aw ay from bars of tilt linkage. Remember that the load requires more vertical space when tilted to the upright position, as well as more horizontal space when tilted to the flat position.
