a. After‐operation Service is particularly important, because at this time the driver inspects his vehicle to detect any deficiencies that may have developed, and corrects those he is permitted to handle. He should report promptly, to the designated individual in authority, the results of his inspection. If this schedule is performed thoroughly, the vehicle should be ready to roll again on a moment’s notice. The Before‐operation Service, with a few exceptions, is then necessary only to ascertain whether the vehicle is in the same condition in which it was left upon completion of the After‐operation Service. The After‐operation Service should never be entirely omitted, even in extreme tactical situations, but may be reduced to the bare fundamental services outlined for the At‐halt Service, if necessary.

b. Procedures. When performing the After‐operation Service, the driver must remember and consider any irregularities noticed during the day in the Before‐operation. During‐operation, and At‐halt Services. The After‐operation Service consists of inspecting and servicing the following items. Those items of the After‐operation Services that are marked with an asterisk (*) require additional Weekly services, the procedures for which are indicated in step (b) of each applicable item.

(1) Item 54, Fuel and Oil. Fill fuel and oil tanks; fill oil tank within 1 inch of top; be sure to put oil in right tank and fuel in left tank; do not interchange caps. CAUTION: When operating under extremely dusty conditions, drain engine oil tank and refill with fresh oil as frequently as excessive contamination of the oil occurs.

(2) Item 55, Engine Operation. Test for satisfactory engine idle without stalling. Accelerate and decelerate engine, noting any tendency to miss or backfire, unusual noises, or vibration that may indicate worn parts, loose mounting, incorrect fuel mixture, or faulty ignition. Investigate any unsatisfactory engine operating characteristics noted during operation. Learn to recognize noise caused by loose primary (front) drive chain. Slack in excess of ½ inch total up‐and‐down motion can cause excessive noise which sounds like engine knock. Remove inspection cover for examination of chain.

(3) Item 57, Horn. If tactical situation permits, test horn.

(4) Item 59, Lights. If tactical situation permits, observe whether blackout and service lights operate with switch in its respective positions, and go out when switched off. Also see that lights are secure, and lenses clean and not broken. Observe whether both filaments of service headlight operate when dimmer switch on left handle bar is moved to its respective positions.

(5) Item 56, Instruments. Before stopping engine, inspect instruments to see that indicator lights are still out. Stop engine. After 30 seconds, turn on switch to see that oil pressure and generator signal lights turn on. CAUTION: Be sure to turn off ignition switch after this test.

(6) Item 58, Glass. Clean rear view mirror, windshield, instrument, and light glass. Examine for secure mounting and breakage.

(7) Item 62, *Battery.

(a) Inspect battery carrier for good condition and secure mounting. Inspect electrolyte level (should be ⁵⁄₁₆ inch above plates). Inspect for any signs of leakage of electrolyte indicating battery has been overfilled, poorly sealed, or damaged. CAUTION: Do not add water unless actually needed.

(b) Weekly. Clean dirt from top of battery, remove battery caps, bring electrolyte level to ⁵⁄₁₆ inch above plates, using clean, drinkable water. Clean terminals or posts if corroded; be sure felt washers are on terminals and properly oiled; tighten terminal bolts cautiously, if loose. Clean and paint battery carrier if corroded.

(8) Item 63, *Accessories and Chain.

(a) Inspect carburetor, air cleaner, generator, and cut‐out relay for loose connections, mountings, or damage. Examine rear drive chain for broken rollers, broken link side plates, and broken or missing connecting link spring clips. Examine rear chain (final drive) for free up‐and‐down movement (slack) midway between sprockets; maximum total allowable deflection is 1 inch, minimum, ½ inch.

(b) Weekly. Tighten any accessory connections found loose. Wipe excess dirt from rear chain. Check front chain for adjustment, and inspect for proper lubrication.

(9) Item 65, *Air Cleaner.

(a) Examine oil cup for excessive dirt and correct oil level. If air cleaner is excessively dirty, clean elements in dry‐cleaning solvent, refill cup with fresh oil. Dip elements in oil in oil cup, replacing elements and attaching oil cup immediately. If gaskets are damaged, replace. Under extremely dusty or sandy conditions it may be necessary to clean and refill the air cleaner more than once daily. Inspect hose for leaks.

(b) Weekly. Inspect air cleaner for proper oil level and excessively dirty oil. Clean and service air cleaner, tighten mounting and hose clamps. NOTE: Early‐type, round air cleaner does not have removable filter elements. Complete cleaner must be removed to wash element.

(10) Item 66, *Fuel Filter (Gasoline Strainer).

(a) Clean cap and screen of fuel filter.

(b) Weekly. Clean cap and screen of fuel filter, remove carburetor bowl drain plug, and drain off water and dirt. Be sure to replace plug, being careful to avoid cross threading.

(12) Item 68, *Tires.

(a) Remove foreign matter such as nails, glass, or stones from tire treads. Inspect tires for abnormal tread wear, cuts, or bruises: also for presence and tightness of valve caps. Inflate tires to 18 pounds front, 20 pounds rear, with tires cool.

(b) Weekly. Replace badly worn or otherwise unserviceable tires.

(13) Item 69, *Springs and Suspension.

(a) Inspect front fork for broken or sagged springs, loose bolts, studs, and nuts.

(b) Weekly. Tighten wheel axle nuts and rear brake sleeve nut. Also tighten rear wheel mounting socket screws very securely.

(14) Item 70, Steering. Inspect steering head for proper adjustment of bearings. Examine steering damper for correct adjustment.

(15) Item 72, *Vents.

(a) Make sure that crankcase breather outlet and rear chain oil supply pipe are clear. Make sure grease drains in front and rear brake side covers are open and clean.

(b) Weekly. Clean crankcase breather outlet, rear chain oil supply pipe, and grease drains in front and rear brake side covers.

(16) Item 73, Leaks, General. Look around mechanism and beneath vehicle for indication of fuel, oil, and grease leaks. Examine around brake drums for evidence of grease in drums or on linings. Normally a few drops of oil may be expected to drip from skid plate.
