4.3.4 Releasing the Feed Unit

After finishing the drilling, the drive shall be released from top of the assembly. In lower pressures, this

can be done by hand. For higher pressures >12 bar it is highly recommended to use the chain block.

- Both of the the adjusting handles ③ shall be gripped, pushed

forward and simultaniously turned counter-

clockwise to release the adusting socket.

- The socket can now be reversed by sliding the power screws

completely off from the drill body

- Release the shaft completely. The chuck inside the drilling

chamber stopps the shaft from comming out.

Warning: If you are unsure about the forces acting on the

shaft while releasing it, use the chain block for this operation.

From the manufacturers experience, it is advisable to use it at a

pressure >12 bar. See chapter 4.6 how to use the chain block.

- The valve has to be closed completely by turning the

ball using proper allen key and turning it 90 degrees.

Since the ball in the hot tap valve has no automatic

stop, you may have to adjust the position

of the ball until it is in correctly closed position.

- The tightness can be controlled by opening the

control cock.

- Connect the hose to the control cock and open it to

release the pressure

CAUTION: Keep enough distance to the

hose while releasing the

pressure to protect yourself.

Make sure the valve is

completely closed !
