Cleaning And Lubrication

The SAW should be cleaned immediately after firing. It should be disassembled into its major groups or assemblies for cleaning.

a. All metal components and surfaces that have been exposed to powder fouling should be cleaned using cleaner, lubricant, preservative (CLP) on a bore-cleaning patch. Use the same procedure to clean the receiver.



b. The gas regulator and piston are cleaned after each firing. To clean the gas regulator and piston, use the scraper tool and solvent. Make sure the gas regulator and piston are dry before assembly.

NOTE: Use a cloth highly saturated in CLP on exterior surfaces to prevent corrosion.

c. After the SAW is cleaned and wiped dry, apply a thin coat of CLP by rubbing with a cloth. This will lubricate and preserve the exposed metal parts under all normal temperature ranges.

d. Lubricate moving parts, as described below, with CLP:

(1) Barrel Group. On the camming surfaces of the bolt-locking lugs.

(2) Operating Rod Group. On the operating rod and spring, the slide assembly, the feed roller, and the bolt-locking lug.

(3) Receiver Group. On all moving parts on the cover assembly and the receiver rails. After lubricating, cycle the components by hand to spread the CLP.

e. Weapons fired infrequently or stored for prolonged periods should have a light film of CLP applied to the interior of the gas plug and the gas regulator and piston immediately after cleaning or after inspection. Preventive maintenance will be performed every 90 days, unlesB inspection reveals more frequent servicing is necessary. The use of the lubricant will not eliminate the requirement for cleaning and inspecting to ensure that corrosion has not formed. Before using, the gas regulator, gas plug, and piston must be clean and free of oil and lubricants. The following procedures apply to cleaning and lubricating the SAW under unusual conditions:

NOTE: CLP is the only lubricant to un on the SAW.

(2) Damp or salty air. Use CLP, grade 2. Clean and apply frequently.

(3) Sandy or dusty areas. Use CLP, grade 2. Clean and apply frequently. Remove excess with a rag after each application.

(4) Below -18 degrees Celsius (0 degrees Fahrenheit). Use CLP, grade 2, generously. Lubricate heavily enough so that it can be spread with finger.

NOTE: Although CLP will provide required lubrication at temperatures between 0 degrees Fahrenheit and -35 degrees Fahrenheit, it will not flow from a 1/2-ounce bottle at temperatures below 0 degrees Fahrenheit.
