8DO NOT modify the jack in any way.
8The load to be lifted should never exceed the rated capacity of the jack.
8The maximum stroke of the jack indicated on the label should never be exceeded.
9The jack should be supported on a solid, level and horizontal surface which is well illuminated and free of obstructions. Never stand
the jack on a surface which may sink.
9The air supply hose should not be worn and connections should be in good condition. Keep the hose clean and away from heat, dirty
areas or sharp edges and do not bend it.
