INTRODUCTION TO PMCS TABLE

a. General. Your PMCS table (Table 2-1)has been provided so you can keep your equip-ment in good operating condition and ready forits primary mission.

b. Warnings and cautions. Always observethe WARNINGS and CAUTIONS appearing inyour PMCS table BEFORE, DURING, andAFTER you operate the equipment. The warn-ings and cautions appear before certain pro-cedures. You must observe these WARNINGSand CAUTIONS to prevent serious injury toyourself and others or prevent your equipmentfrom being damaged.

c. Explanation of table entries.

(1) Item number column. Numbers in thiscolumn are for reference. When completing DAForm 2404, Equipment Inspection and Mainte-nance Worksheet, include the item number forthe check/service indicating a fault. Itemnumbers also appear in the order that youmust do checks and services for the intervalsIisted.

(2) Interval column. This column tells youwhen you must do the procedure in the pro-cedure column. BEFORE procedures must bedone before you operate or use the equipmentfor its intended mission. DURING proceduresmust be done during the time you are operat-ing or using the equipment for its intended mis-sion. AFTER procedures must be done immedi-ately after you have operated or used theequipment.

(3) Item to Check Service column. Thiscolumn provides the Iocation and the item tobe checked

(4) Procedure column. This column givesthe procedure you must do to check or service

the item listed in the Check/Service column toknow if the equipment is ready or available forits intended mission or for operation. You mustdo the procedure at the time stated in the in-terval column.

(5) Not fully mission capable if: column.Information in this column tells you what faultswill keep your equipment from being capable ofperforming its primary mission. If you makecheck and service procedures that show faultslisted in this column, do not operate the equip-ment. Follow standard operating procedures formaintaining the equipment or reporting equip-ment failure.

GENERAL

a. Corrosion. Refer to page 1-2.

Unusable CARC mixtures may beconsidered hazardous waste andmay require disposal in accor-dance with Federal, state, DOD,and DA hazardous waste regula-tions. Consult the installation en-vironmental office for properdisposal guidance. Mixed CARChas a flashpoint of approximately38°F (3°C) due to the incor-poration of solvents and is highlyflammable.

b. Touchup/Spot Painting. Painting at theoperator level is limited to touchup/spot paint-ing. CARC paint that has been opened must beused within 8 hours or it will deterioratebeyond use. Mix only what is needed for im-mediate use. Refer to TM 43-0139.

c. I f YourTroubleshoot

Equipment Fails to Operate.with proper equipment. Report

any deficiencies using the proper forms. SeeDA PAM 738-750.

PMCS PROCEDURES

a. Perform PMCS each day vehicle isoperated. If vehicle is not being operatedregularly, start and run engine for approx-imately 1/2 hour at least once a week. Whileengine is running, exercise crane controls.Perform only the PMCS required for runningengine and checking crane controls.

b. Perform weekly as well as before operations PMCS and check fluid levels if:

(1) You are the assigned operator andhave not ‘operated the item since the lastweekly.

(2) You are operating the item for thefirst time.

c. While you perform PMCS, have“checker” tools with you and keep an eyeout for the following:

(1) Loose bolts. A loose bolt can be dif-ficult to spot without using a wrench.However, you can often identify loose boltsby observing loose or chipped paint aroundbolt head and bare metal or rust at its base.Tighten loose bolts.

(2) Damaged welds. Damaged weldsmay be detected by observing rust or chippedpaint where cracks occur.

(3) Frayed electrical wires and looseconnectors. Check electrical wiring for cracksdue to aging and exposed wires that couldcause an electrical short. Tighten looseclamps and connectors.

Equipment operation is allow-able with minor leakages (classI or 11). Of course, you mustconsider the fluid capacity inthe item/system being checked/inspected. When in doubt, noti-fy unit maintenance personnel,

When operating with class I orclass II leaks, continue to checkfluid levels as required in yourPMCS.

Class Ill leaks should bereported to unit maintenancepersonnel.

NOTE

Fluid leakage classificationsapply only to hull components.

(4) Fluid leakage. Leaks are divided intothree classifications. Compare leak with thefollowing definitions:

Class I Seepage of fluid (as in-dicated by wetness ordiscoloration) not greatenough to form drops.

Class II Leakage of fluid greatenough to form drops butnot enough to causedrops to drip from itembeing checked/inspected.

Class Ill Leakage of fluid greatenough to form drops thatfall from the item beingchecked/inspected.

d. If your equipment does not perform asrequired, refer to troubleshooting proceduresin chapter 3 for possible problems. Reportany malfunctions or failures on the proper DAForm 2404, or refer to DA PAM 738-750.

e. If an assembly must be removed and/ordisassembled in order to perform PMCS, referto the maintenance procedures in chapter 3.
