WARNING

Fuel is very flammable and can explode easily. To avoid serious injury or death, keep fuel away from open fire and keep fire

extinguisher within easy reach when working with fuel. Do not work on fuel system when engine is hot. Fuel can be ignited by hot

engine. When working with fuel, post signs that read NO SMOKING WITHIN 50 FEET (15 m).

Pressure test procedure results in fuel under high pressure. Be sure that pressure test device is connected properly and use

safety shield during test. Failure to do so may result in injury to personnel.

P-D-680 (Type II) is a flammable solvent that is potentially dangerous to personnel. Keep away from heat, sparks or open flame.

Flash point of solvent is 138 degrees F (59 degrees C). Use only in a well ventilated area. Inhaling vapors over a period of time

can cause headache and drowsiness. Use gloves to prevent irritation or inflammation of the skin. Solvent absorbed through the

skin can result in internal disorders. If contact occurs, wash the affected area with water for 15 minutes. For eyes, flush with water

and then seek immediate medical attention.

Improper cleaning methods and use of unauthorized cleaning solvents may injure personnel and damage equipment. Refer to

TM9-247 for correct information.

Eye shields must be worn when cleaning with a wire brush. Flying rust and metal particles may cause injury to personnel.

Particles blown by compressed air are hazardous. Make certain the air stream is directed away from user and other personnel in

the area. To prevent injury, user must wear protective goggles or face shield when using compressed air.

CAUTION

Washing oil seals, electrical cables and flexible hoses with dry cleaning solvents or mineral spirits will cause serious damage or

destroy materials.
