2-9. OPERATING PROCEDURES
The cart can be configured to provide nitrogen for pressurizing tires, accumulators and struts directly from the nitrogen
tank when tank pressure is adequate or by increasing the nitrogen supply pressure with the booster pump. The booster
pump can be driven by the supply nitrogen or by compressed air when available.
WARNING
Always confirm that the pressure produced by the High Pressure Nitrogen Servicing Cart does
not exceed the servicing pressures specified in the applicable aircraft technical manuals.
WARNING
Verify the correct tire inflation pressure in the aircraft manual before inflating.
CAUTION
Do not exceed 30 inch pounds of torque when connecting high pressure inflation chuck to any
charging fitting.
2-10. NITROGEN CHARGING DIRECTLY FROM THE SUPPLY TANKS (See Fig. 2-1)
a.
High Pressure Servicing:
(1)
Setup the cart per paragraph 2-5. Use one or two tanks with adequate pressure to complete the charging
procedure for the given accumulator or strut.
(2)
Slowly open valve(s) located on the nitrogen tanks.
(3)
Check tank pressure on the tank pressure gauge, G1, to make sure that tank pressure is higher than the
required servicing pressure per the applicable aircraft manual.
