_4. Serve._ This usually consists of performing special operations, such as replenishing battery water, and draining and refilling units with oil.
_5. Tighten._ All tightening operations should be performed with sufficient wrench‐torque (force on the wrench handle) to tighten the nut according to good mechanical practice. Use torque‐indicating wrench where specified. Do not overtighten, as this may strip threads, or cause distortion. Tightening will always be understood to include the correct installation of lock washers, lock nuts, and cotter pins provided to secure the tightening.
(_e_) When conditions make it difficult to perform the complete preventive maintenance procedures at one time, these can sometimes be handled in sections, planning to complete all operations within the task if possible. All available time at halts and in bivouac areas must be utilized, if necessary, to assure that maintenance operations are completed. When limited by the tactical situation, items with special services in the columns should be given first consideration.
(_f_) The numbers of the preventive maintenance procedures that follow are identical with those outlined on W.D. AGO Form No. 463, which is the Preventive Maintenance Service Work Sheet for Motorcycles. Certain items on the work sheet that do not apply to this vehicle are not included in the procedures in this manual. In general, the numerical sequence of items on the work sheet is followed in the manual procedures, but in some instances there is deviation for conservation of the mechanic’s time and effort.
(5) SPECIFIC PROCEDURES. The procedures for performing each item in the 1,000‐mile maintenance procedures are described in the following chart. Each page of the chart has a column at its left edge corresponding to the 1,000‐mile maintenance.
NOTE: If tactical situation does not permit a full road test, perform items 2, 3, 4, 5, 6, 7, 8, 9, 12, and 14, which require slight or no movement of the vehicle. When a road test is possible, it should be for preferably 5, and not over 10 miles.
=Before‐operation Inspection.= Perform Before‐operation Service listed on W.D. Form No. 418. “Driver’s Trip Ticket and Preventive Maintenance Service Record” (described in par. 15), to determine if vehicle is in a satisfactory condition to make the road test safely.
