NITROGEN (N
2
) GAS PRESSURE ADJUSTMENT
The hammer will not operate properly and may not start due to an incorrect gas charge.
Follow the procedure described below to adjust nitrogen (N
2
) gas pressure.
WARNING!
DO NOT STAND NEAR THE HAMMER WHEN ADDING NITRIGEN. THE
TOOL MAY EJECT SUDDENLY AND CAUSE SEVERE INJURY.
1. Gas Pressure Testing.
a. With the gas charger disconnected from the hammer, plug the inlet (the nitrogen
hose connection port) of the gas charger with the cap provided, then turn the
“T” handle fully to the left (counter clockwise.)
b. Remove the gas valve cap located on the hammer back cap and attach gas charger,
see Figure 7.

2
) Supply
c. Turn the “T” handle on the gas charger valve clockwise, and then measure the N
2
gas pressure.
2. Releasing Gas Pressure (if over charged or prior to disassembly)
a. Test the gas pressure as described in paragraph 1.
b.
For disassembly loosen the bleeder screw on the gas charger very slowly and
release the N
2
gas. Watch the pressure gauge until the nitrogen pressure is fully
released. (see Figure 7 and 8.)
c. If overcharged close the Bleeder Screw when the gas pressure reaches the correct
gas pressure shown on Table 10, Page 26, then turn the “T” handle to the left
(counter clockwise).
d. Finally, remove the gas charger. Install and tighten the gas valve cap.
3. Refilling Nitrogen (N
2
) Gas
a. Perform paragraph 2 procedure.
b. Remove the cap on the gas charger, nitrogen hose connection port. See Fig 9.
c. Attach the N
2
gas pressure regulator to the gas container. Connect the nitrogen
(N
2
) Supply tank to the gas charger with the charging kit hose.
