37. Cleaning Pneumatic Machines.—It is not necessary to take the gun apart nor disconnect the hose to clean the machine. Thinner can be run thru the device without loss by placing a small can of reducer of the last material used in the machine, and forcing it thru in the usual manner.
38. Directions for Cleaning Machine.—Close right-hand Air Valve and open release valve. Unscrew air nozzle a few turns. Obstruct outlet with thumb and pull trigger. Spraying pressure is thus forced thru gun and fluid hose and the material backed into the container. It is advisable frequently to run thinner thru the machine as follows: (1) Place small can of thinner in center of container directly beneath fluid tube. (2) Replace cover and tighten wing-nuts. (3) Close left-hand air valve and open right-hand air valve. Pressure on container will force thinner thru the machine and clean perfectly without loss. Do not use spraying pressure in cleaning. The thinner can be used again for either cleaning or thinning purposes.
