If your OKC-3S Multipurpose Bayonet System (USMC only), M7 Bayonet-Knife, M10 Bayonet-Knife Scabbard, or M9 Multipurpose Bayonet System needs improvement, let us know. Send us an EIR. You, the user, are the only one who can tell us what you do not like about your equipment. Let us know why you do not like the design or performance. If you have Internet access, the easiest and fastest way to report problems or suggestions is to follow the instructions and links below. ALL non-Aviation/Missile Warranty EIRs and PQDRs must be submitted through the Web Product Quality Deficiency Reporting (PQDR) site. The Web PQDR site is: http://www.nslcptsmh.csd.disa.mil/webpqdr/webpqdr.htm. New accounts can be established at the following address: http://www.nslcptsmh.csd.disa.mil/accessforms/uarform.htm. You may also submit your information using an SF 368 (Product Quality Deficiency Report).

CORROSION PREVENTION AND CONTROL (CPC)Corrosion Prevention and Control (CPC) of Army materiel is a continuing concern. It is important that anycorrosion problems with this item be reported so that the problem can be corrected and improvements can bemade to prevent the problem in future items. Corrosion specifically occurs with metals. It is an electrochemicalprocess that causes the degradation of metals. It is commonly caused by exposure to moisture, acids, bases, orsalts. An example is the rusting of iron. Corrosion damage in metals can be seen, depending on the metal, astarnishing, pitting, fogging, surface residue, and/or cracking. Plastics, composites, and rubbers can also degrade.Degradation is caused by thermal (heat), oxidation (oxygen), solvation (solvents), or photolytic (light, typically UV)processes. The most common exposures are excessive heat or light. Damage from these processes will appearas cracking, softening, swelling, and/or breaking. SF 368, PQDR, should be submitted to the address specified inPAM 750-8, The Army Maintenance Management System (TAMMS) Users Manual.

DESTRUCTION OF ARMY MATERIEL TO PREVENT ENEMY USE

Refer to TM 750-244-7 for procedures concerning destruction of this materiel.

PREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS)

TM 9-1005-237-23&P

FIELD MAINTENANCEPREVENTIVE MAINTENANCE CHECKS AND SERVICES (PMCS) INTRODUCTION

GENERAL

To ensure maximum operational readiness, it is necessary that the M7 Bayonet-Knife, M10 Bayonet-KnifeScabbard, M9 Multipurpose Bayonet System, and OKC-3S Bayonet-Knife (USMC only) be systematicallyinspected at regular intervals so defects may be discovered and corrected before they result in seriousdamage or failure.

PREVENTIVE MAINTENANCE CHECKS AND SERVICES

Work Package (WP) 0005 lists those Preventive Maintenance Checks and Services (PMCS) to be performed attheir designated intervals.

During periods of inactivity, perform PMCS quarterly unless inspection reveals more frequent servicing isnecessary. An inactive bayonet is one which has been stored in an arms room for a period of 90 days withoutuse. The bayonet may or may not have been assigned to an individual. Normal cleaning (PMCS) of an inactivebayonet will be performed every 90 days. Should the unit armorer detect corrosion on a bayonet/scabbard prior tothe end of the 90-day period, the PMCS shall be performed immediately.

1. ITEM NO. The first column contains the item number which shall be used as a source of item number forthe Technical Manual (TM) Item No. column on DA Form 2404, Equipment Inspection and MaintenanceWorksheet, in recording results of PMCS. Checks and services are numbered in disassembly sequence.

2. INTERVAL. The INTERVAL column states when to perform the inspection or service.3. ITEM TO BE CHECKED OR SERVICED. This column lists the item to be inspected.4. PROCEDURES. This column contains all the information required to accomplish the checks and services.5. EQUIPMENT NOT READY/AVAILABLE IF. This column contains a brief statement of the condition (e.g.

malfunction, deficiency) that would cause the covered equipment to be unavailable to perform itsassigned mission.

CORROSION PREVENTION AND CONTROL (CPC)WP 0006 provides instructions regarding Corrosion Prevention and Control (CPC).

General - Continued

NOTE Where the word "lubricant" is cited in this Technical Manual (TM), interpret to mean

Cleaner, Lubricant and Preservative (CLP), lubricating oil, Weapons semifluid (LSA), orLubricating oil Weapons (LAW) can be utilized as applicable. The following constraintsmust be adhered to:

Under all but the coldest arctic conditions, LSA or CLP are the lubricants to use on thebayonet/scabbard. Either can be used at -10F (-23C) and higher. However, do notuse both on the same bayonet/scabbard at the same time.

LAW is the lubricant to use during cold arctic conditions, +10F (12C) and lower.

Any of the lubricants can be used from -10F (-23C) to +10F (12C).

Do not mix lubricants on the same bayonet/scabbard. The bayonet/scabbard must bethoroughly cleaned during change from one lubricant to another. Cleaning solvent isrecommended for cleaning the bayonet during change from one lubricant to another.Do not use cleaning solvent on the scabbard or the handle.
