1. To avoid damages to the pushing air bag at deployment,start by carefully clearing the edges of the stone block of possible debris;

2. Consult the thrust table to determine the types and number of pushing air bag required to spread an opening 15cm between the sawed block and the quarry;

3. Fasten one  end of two pull back ropes to the rings at the upper edge the bag and tie the other ends to fixed point;

4. Link the air supply through pressure gauge tube to the bag;

5. Begin the inflating  operation by opening the ball valve connected to the bag;

6. Continue inflating until obtaining opening of 10-15cm opening ,place appropriate metal wedges under the stone block;

7. Overlap the bags until overtuning block;
