NITROGEN (N
2
) GAS PRESSURE ADJUSTMENT
The hammer will not operate properly and may not start due to an incorrect gas charge. It
is normal for the nitrogen pressure to rise as the hammer warms up. For that reason, a
range of pressures is stamped on a plate near the charge valve. When ambient
temperatures of over 100
0
F are a routine occurrence, the nitrogen charge can raise enough
to stop the hammer. See Table 11, Page 26 for charge settings at high ambient
temperatures.
Follow the procedure described below to adjust nitrogen (N
2
) gas pressure.
WARNING!
DO NOT STAND NEAR THE HAMMER WHEN ADDING NITROGEN. 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.
