– Raise the load using its entire length and distribute it evenly on both folding fork arms. Incorrect lifting of the load could cause the load to tip or slip and cause serious injuries. Folding fork armsTypes KGA, KGI, and DuoLoc V1.07/2021... - Page 13 – Always exercise caution when approaching the load to be lifted. In types KGA and KGI, the fork blade is not secured in the operating position. In case of collision, e.g., with a loading edge, the fork blade can fold up inadver- tently and therefore cause severe damage and serious injuries.
