TM 9-2320-366-20-4 CAUTION Full system air pressure is required before calibrating load sensing valve. Failure to comply may result in incorrect calibration of load sensing valve. (18) Close air tanks (TM 9-2320-366-10-1). NOTE Hold engine speed at high idle for at least one minute after air pressure stabilizes. (19) Start engine (TM 9-2320-366-10-1) and increase engine speed to high idle. NOTE REAR BRAKE AIR pressure gage should read approximately 120 psi. If REAR BRAKE AIR pressure gage reads less than 115 psi shut down engine and perform step (19) again. (20) Decrease engine speed to low idle. (21) Depress brake pedal (TM 9-2320-366-10-1). NOTE STE/ICE-R attached to rear service brake air chamber should indicate air pressure within limits shown in Table 11-2. Air Chamber Pressure Limits. (22) Note reading on STE/ICE-R while brake pedal is depressed. Table 11-2.
