| | | It is recommended that the following service be performed on a daily basis. 1. The Gun is built at the factory with, P/N 21222-00 Lubricate. This is a water soluble lubricate, not affected by most solvents. When maintaining the Gun, it is recommended that this is used as outlined on "Lubricate Page". Clean the Gun using a brush and a appropriate clean solvent. 2. Inspect Gun Valve Needle shafts, making certain they are clean and free of over-spray or foreign material. Clean and lubricate as required. 3. Inspect the Gun Packings, Needles and Boat seats for catalyst or material leakage. If leakage does occur, correct at once! If material leaks (or drips) out of the nose of the gun, this indicates that there is a bad needle/seat condition. If material leaks out of the back of the needle stem, this indicates loose or worn packings and may be repacked by tightening the packing nuts, P/N 20509-00 1/8 turn each until leak stops. Test trigger to verify spring can return needle to seat. 4. Maintain a reasonable stock level of "wear" items such as Packings, Seals and O-Rings 5. If Spray Gun is leak tested, be sure to dry gun thoroughly. 6. Never leave Spray Gun immersed in any liquid. | | |
