INFLATION AND DISCHARGING OF NITROGEN IN THE BACK HEAD
INFLATION
1. Remove the inflation valve cap from the the back head.
2. Connect the end of the pressure gauge adapter (1) to the
inflation valve on the back head.
3. Remove the end cap (4) to uncover the pipe fitting for the
hose.
4. Connect the hose from the pipe fitting to your Nitrogen
tank.
5. Ensure that the pressure relief valve (3) is tightened.
6. Press and hold the pressure release pin (2) to begin
inflating the back head with Nitrogen.
7. When the appropriate pressure is reached, stop pressing
the pressure release pin (2).
8. Disconnect the hose and reattach the end cap (4).
9. Disconnect the end of the pressure gauge adapter (1) and
securely reattach the inflation valve cap to the back head.
DISCHARGING
We do not recommend trying to disassemble or
assemble the back head, but if such action is taken,
the Nitrogen must be fully discharged first. If the
through bolts atop the back head are loosened before
discharging the Nitrogen, an explosion could occur.
1. Remove the inflation valve cap from the back head.
2. Connect the end of the pressure gauge adapter (1) to the
inflation valve on the back head.
3. Loosen the pressure relief valve (3).
4. Press and hold the pressure release pin (2) to begin
discharging Nitrogen from the back head.
5. When all of the Nitrogen has been discharged, stop
pressing the pressure release pin (2).
6. Disconnect the end of the pressure gauge adapter (1) and
securely reattach the inflation valve cap to the back head.
