Cleaning

TM 10-7360-204-13&P Change 11 3-5/(3-6 blank) c. Cleaning. Dry cleaning solvent, P-D-680 (Item 5, Table F-1), used to clean parts is potentially dangerous to personnel and property. Avoid repeated and prolonged skin contact. Do not use near open flame or excessive heat. Flash point of solvent is 100 degrees F to 138 degrees F (38 degrees C to 59 degrees C). Avoid breathing dust or fumes or placing generator to mouth. Never try to blow air through the generator to remove any matter. Dust and fumes could cause lead poisoning. Always bury an unserviceable generator if in combat and follow local policy during peacetime. (1) Clean exterior of generator with a wire brush and/or cloth with cleaning solvent, P-D-680 (Item 5, Table F-1). (2) Clean fuel feeder tube (9) by rinsing in a solvent and replace immediately to eliminate loss or damage. Burner unit will fail to light if fuel feeder tube is lost, clogged or dented. d. Repair. The only repair that can be done on the generator is repairing orrepacking the generator flame valve assembly. Refer to figure 3-2. (1) Take apart the generator valve stem and wire brush it. (2) Coat valve stem threads and packing nut threads with anti-seize compound. (3) Replace packing as needed and reassemble valve. (4) Tighten packing nut until a slight bind is felt. Special care must be used when replacing orifice nut on generator. The valve stem should not protrude into orifice nut when replacing this nut. (5) Tighten orifice nut. (6) Close generator flame valve by turning flame valve knob clockwise (Item 5, Figure 3.1). Figure 3-2. Packing the Generator Flame Valve. Improper packing of the generator valve assembly could result in injury to operating personnel (7). Check generator flame valve assembly for proper operation of the generator flame valve by turning the flame valve knob counterclockwise to open the valve. The knob should positively stop when completely opened. Any knob failing to positively stop when opened should be checked by tightening the packing nut or replace the packing WARNING NOTE WARNING
