Before use on missions or for training, flame throwers must be charged, filled, and serviced. Charging with compressed air or compressed nitrogen is described in Paragraphs [32 and 33]; filling with fuel in Paragraphs [34] through [40]; and servicing in Paragraphs [50] through [56]. Test for pressure. ([Par 53 d])
17. CONNECTING TANK GROUP AND GUN GROUP.
If a charged and filled tank group has been brought up to replace an emptied one:
a. Place the new tank group on the ground with the tank coupling on top. If the filling is thickened fuel, allow the tank group to rest in this position for from 1 to 2 minutes.
b. Remove coupling plug from new tank group and disconnect gun group from emptied tank group. Place unthreaded end of fuel hose in tank coupling and lock in place. ([Par 70])
c. Lock the coupling plug in the emptied tank group.
18. LOADING WITH IGNITION CYLINDER.
a. General. Just before the start of a mission, load an unused ignition cylinder into the ignition head. (M1 and E1 ignition cylinders are identical and may be used interchangeably.) Cylinders are packed two to a can. Do not open cans until ready to load for a mission. The second cylinder in the can should be used in another flame thrower on the same mission or as soon as possible after opening the can. Partly used cylinders may be employed in training.
b. Precautions. Care must be taken, whenever cylinders are handled, to avoid any blows or pressure against the metal match ends. ([Fig 13]) Face, hands, and other parts of the body should never be exposed to front of cylinder or front of gun.
