INSTRUCTIONS

WARNING

Drycleaning solvent P-D-680 is toxic and flammable. Wear protective

g o g g l e s and gloves and use only in well-ventilated area. Avoid contact with

s k i n , eyes, and clothes and do not breathe vapors. Do not use near open

flame or excessive heat. Flash point is 100 -1380 F (38-50C). If you

become dizzy while using drycleaning solvent, get fresh air immediately and

g e t medical aid. If contact with eyes is made, wash your eyes with water

a n d get medical aid immediately.

N e v e r use gasoline to clean parts. Gasoline is highly flammable. Serious

personal injury could result if fuel ignites during cleaning.

CAUTION

Petroleum solvents may damage parts that are in contact with hydraulic

fluids.

To prevent damage to equipment, do not clean tires, lubricant seals, rubber

h o s e s , or electrical components with solvent mixture.

Cleaning Solvents. Use only approved cleaning solvents to clean parts. Drycleaning solvent

SD-2 (P-D-680) is commonly used. Always work in a well-ventilated area.

WARNING

T o prevent injury, compressed air used for cleaning and drying purposes will

n o t exceed 30 psi (207 kPa). Use only with effective chip guarding and

p e r s o n a l protective equipment (goggles/shield, gloves, etc.).

Removing Deposits. After soaking parts in solvent, wash away deposits by flushing or spraying.

Where necessary, brush with a soft-bristle brush moistened in solvent. Use compressed air to

dry all parts, except bearings. Bearings must be allowed to air dry.

Tools. Do not use abrasive wheels, or compounds in cleaning parts, unless called for in

detailed instructions. These procedures may weaken a highly stressed part.

Ball and Roller Bearings. When cleaning ball or roller bearings, place them in a basket and

suspend them in a container of drycleaning solvent. If needed, use a brush to remove bearing

before solid particles are removed to prevent damaging races and balls. When bearings have

been cleaned, coat them lightly with lubricating oil to remove solvent. Refer to TM 9-214 for

additional instructions on cleaning bearings.

Rubber Parts. Do not clean rubber parts in drycleaning solvent. Clean by washing with a mild

solution of soap and water. Wipe with a clean, dry, lint-free cloth.
