Instruction Manual

When lifting up the heavy load

  1. Engage the accessory lever into the eye of the release screw, and turn clockwise to tighten up the release screw.

 

2. Push the lever grip from the top with your hand to remove the lever hook.

 

3. The Stepped Block enables the Lifting Jack to be used to lift an item with larger gap, and will lift the item further with less penetration.

   ①Attach the stepped block to the tool using the accessory countersunk screw.

   ②Insert the entire stepped block under the item to be lifted.

When keeping the heavy load

Once the item has been lifted to the desired height, or to the maximum height on the step used, the safety block should be inserted into the gap, and will keep the item safely.

When lowering the heavy load

Engage the accessory lever into the eye of the release screw, and turn counterclockwise slowly. The release valve will be opened to let the wedge (and step) fall.
The wedge (step) will fall automatically if under load.

※Never loosen the release screw completely in a breath as the step (wedge) may drop all of a sudden to overturn the heavy object, causing a serious accident.
