Spare and wearing parts
Description
Air filling connector
Braided hose for outlet
7.2
Replacement of spare parts
7.2.1
Replacing the air filling connector
Risk of injury due to pressure in the hoses
High pressure in the hoses might cause the
hoses to buckle and cause injury.
¶
Ensure that the nitrogen pressure gauge
reads 0 bar before replacement.
1. Switch off the master switch of the NTI 105.
2. Rotate the safety valve (Fig. 3, Pos. 2) in the anti-
clockwise direction till the pressure in the nitrogen
pressure gauge reads 0 bar.
!
Ensure that you tighten the safety valve of the tank
after releasing the pressure. If the safety valve is
not tightened, the nitrogen filled into the tank will
escape and the operating pressure of 8 bar will not
be achieved.
3. Loosen the hose clip that fastens the filling nozzle to
the braided hose.
4. Disconnect the filling nozzle from the braided hose.
5. Connect the new filling nozzle connector.
6. Place the hose clip and tighten the screws.
i
Ensure that the orientation of the filling nozzle is in
the correct position. To check, connect the filling
nozzle to a tire. If the braided twists, repeat the
above procedure and adjust the position of the filling
nozzle.

Replacing the braided hose for outlet
1. Switch off the master switch of the NTI 105.
Risk of injury due to pressure in the hoses
High pressure in the hoses might cause the
hoses to buckle and cause injury.
¶
Ensure that the pressure of the nitrogen
tank is less than 2 bar before replace-
ment.
2. Rotate the safety valve (Fig. 3, Pos. 2) in the anti-
clockwise direction till the pressure in the nitrogen
tank drops to 2 bar.
!
Ensure that you tighten the safety valve of the tank
after releasing the pressure. If the safety valve is
not tightened, the nitrogen filled into the tank will
discharge and the operating pressure of 8 bar will
not be achieved.
3. Disconnect the braided hose from the quick coupler
at the digital port.
4. Disconnect the male connector from the hose.
5. Disconnect the air filling connector. Refer to chapter
7.2.1 for disconnecting the air filling connector.
