4.5Operation of the Load Limiter

4.5.1If a hoist is used to lift a load that exceeds the hoists rated capacity, the load limiter will cause the hoist to automatically stop lifting.

4.5.2If the hoist stops lifting automatically, lower and remove the load from the hoist.

4.5.3If the load is at or below the hoist’s capacity rating and the hoist stops lifting automatically, the load limiter may need adjustment.

Check air line pressure to ensure adequate pressure at the hoist.

If pressure is adequate, adjust the load limiter. For load limiter adjustment, refer to Section 7.
