Visit Visit our website This film is a black-and-white instruction film presented by The United States Army – 2659, for the US Army portable flamethrower M2A1-7. It shows in detail how to charge pressure tanks using either the M1A1 power-driven reciprocating compressor designed specifically for the M2A1-7 or commercial compressed gas cylinders. It further includes detailed safety instructions. The M2A1-7 shown was a flamethrower used by the American troops during the Vietnam War. It is the updated version of the M2A1-2 unit which was used during The Korean War, and a variant of the M2 which was developed during WWII. “Portable Flame Thrower M2A1-7” – “Pressure Charging” title banners (00:18). Two US Army soldiers use the portable flame thrower (00:37). The pressure tanks of the M2A1-7 (00:55). A power-driven compressor and commercial compressed gas cylinders can be used to charge the flame throwers pressure tanks (00:59). The M1A1 power driven reciprocating compressor designed specifically for the M2A1-7 (01:11). One soldier opens a commercial compressed gas cylinder (01:20). He lays all the gas cylinders down and chucks them to prevent rolling and shows one of two ways to charge the M2A1-7 (01:37). He removes the valve caps (01:49) and attaches a t-connector on all four cylinders (01:55). He tightens the adapter nut using a wrench (02:11) and secures all filling valves (02:21). He checks the charging lines for possible cracks (02:31). The charging lines are then connected to the check valve of the flame thrower’s pressure tank (02:45). The M2A1-7 is now charged by opening the fuel-tank bleeder valves and each cylinder valve one by one to maximize pressure (03:26). The soldier then closes all cylinder valves (04:49) and disconnects the charging lines from the pressure tanks (04:59). The soldier now shows the second way of charging the portable flame thrower using the gasoline engine four-cylinder three-stage power-driven compressor (05:04). The compressor tanks are attached to the skid-mounted compressor (05:23). The other end of the charging line is connected to the check valve on the pressure tank (05:55). The soldier checks that the pressure tanks and bleeder valves are closed, and the fuel tank valves are open (06:03). He starts the power-driven compressor and builds enough pressure to charge the flame thrower (06:20). He opens the bleeder valves on the manifold (06:44) and disconnects the pressure tanks (06:49). He checks the pressure s by inserting a pressure tank gauge in the tank (06:55). Safety instructions are given while the soldier shows how to properly use and inspect the condition of the pressure tanks, cylinders, and the compressor (07:08).
