GAS CHARGE
DISCHARGING THE GAS PRESSURE
PROCEDURE
Remove the valve cap only, not the charge valve assembly!
5. Tighten the charging
adapter cap (g6).
6. Turn the T-handle (g2)
clockwise. As the T-
handle is screwed in, a
resistance is
encountered. By turning
the T-handle (g2)
further, the nitrogen gas
pressure will be
indicated on the
pressure gauge (g8).
Stop turning the T-
handle when the gauge
reads pressure. Do not
over tighten.
7. Loosen the charge adapter
cap (g6) VERY SLOWLY.
The gas pressure will
gradually decrease to
zero; then REMOVE THE
CAP.
8. Remove the charge
adapter (g1) from the
hammer.
9. Remove NPK adapter
part no. 30604100.
10. Install existing plug.
