RING-PISTON 2A4311 - Caterpillar

of Change: A Caution Label Form SEHS7605 is now used on the 0 to 1000 psi 5P4146 Pressure Gauge which is a part of the 5P4150 Nozzle Testing Group. The label is installed directly on the face of the gauge. The caution label is used to help the operator remember to close the protector valve for the 0 to 1000 psi gauge before direct injection nozzles are tested. If this is not done, damage to the gauge can be the result.
The SEHS7605 Caution Label has the words "CAUTION Close protector valve for this gauge before testing direct injection nozzles."
Adaptable To: Nozzle testing groups that are currently made have the caution label installed on the gauge. The caution label will not be installed on existing nozzle testing groups in the Parts Department. The SEHS7605 Caution Label can be ordered for installation on 5P4146 Pressure Gauges in earlier 5P4150 and 8S2242 Nozzle Testing Groups that do not have the label.
