Drycleaning solvent, P-D-680, used to clean parts is potentially dangerous to personnel and property. Avoid
repeated and prolonged skin contact by wearing rubber or solvent impermeable gloves when handling the
solvent or material wet with drycleaning solvent. Wash hands immediately after exposure with soap and
water and use a lanolin based skin cream to prevent skin drying. Do not use near open flame or excessive
heat. Flash point of solvent is 100F (38C). Ensure that ventilation adequate to reduce solvent vapor
concentrations below acceptable threshold limit values is provided.
(1) Clean strainer with dry cleaning solvent, P-D-60. Dry thoroughly.
(2) Replace strainer, glass bowl and gasket.
(3) Replace bail and tighten bail nut.
NOTE
Water in the strainer is an indication of water in fuel tank. If water is found in fuel line strainer, the fuel
tank should also be serviced to eliminate water.
