Do not lift a load on the end of the toe. Fully engage the load with the toe.
IMPORTANT: When lifting by the toe, wedge the head of the jack on the load to avoid bending the column.
2. Turn the release valve knob in a clockwise direction until it is snug.
3. Pump the jacking lever in an up and down motion.
Lowering a Load
1. Slowly loosen the release valve knob by turning it in a counterclockwise direction. The more the knob is loosened,
the faster the load will be lowered. To stop the jack from lowering a load, tighten the release valve knob by turning
it in a clockwise direction.
