CAMERA 5347710 - Caterpillar

As seen in the chart, the pressure shown on the gauge has no direct relation to the amount of Halon in the bottle. As an example: 80% of the Halon in a bottle can be lost, but because of Halon's pressure characteristics, 250 Psi (1724 kPa) will still be shown on the gauge. To determine (tell) how much Halon is in a bottle, use a scale to check its weight. The weight of a full bottle is 60 2 lb (27 1 Kg).
If a dealer has a D10 Tractor in his area, our recommendation is to find a local source to service the fire suppression system before service is needed.
