Procedures.

TM 38-260

(1) Remove all production materials and parts (i.e. in-process parts, raw materials, and bulk process

materials such as quench oils, chemicals, acids, etc.)

(2) Remove such items as covers, inspection plates, and guards, as necessary, to facilitate removal of

manufacturing residue. Standard accessories and attachments, such as chucks, face plates, steady rests, tool holders,

grinding wheels, consumables, dies, jigs, arbors, and fixtures, shall be detached prior to external cleaning.

(3) Each unit containing hydraulic systems shall be tested for polychlorinated biphenyl (PCB) before

draining. Further processing or decontamination of these systems shall be accomplished prior to shipment or preparation

for long term storage.

(4) Drain the coolant system of all soluble and cutting type fluids. Remove residual sediment, sludge, and

manufacturing residue from accessible reservoirs, drip pans, and machine voids.

(5) Clean all exterior machine surfaces (precision, painted, and unpainted), removing manufacturing

residue, such as shop dirt, metal chips, and contaminants, with EPA approved cleaning solvents. Precession and bare

metal surfaces cleaned with cleaning solvent shall be thoroughly dried and a protective coat of preservative oil P-10,

grade 30 of table 2-1, shall be applied.

CAUTION

Care shall be exercised during the cleaning operation to

prevent damage or contamination to the electrical

systems, motors, electronic components, and precision

bearings from the cleaning solvent.

(6) Install a sufficient quantity of solution A in any coolant reservoir(s) to permit free circulation of the

solution through the pump and piping system when the equipment is cycled.

Solution A : One part lubricating oil P-10, type I, grade 30, of table 2-1, and nine parts dry cleaning solvent.

NOTE

If the coolant system is of such a size that it would not

be economical to flush with the cleaning fluid solutions,

the coolant pump may be disconnected to prevent

operation during cycling.
