6 SECTION I INTRODUCTION AND GENERAL DESCRIPTION 1-1. INTRODUCTION. 1. Scope. This manual contains instructions for the use of direct support and general support personnel maintaining the forklift truck as allocated by the Maintenance Allocation Chart. It provides information on the maintenance of the equipment which is beyond the scope of the tools, equipment, personnel, or supplies normally available at organizational maintenance. 2. Demolition and Administrative Storage. a. For information on the administrative storage of this equipment, refer to TM b. For information on the demolition of this equipment, refer to TM Maintenance Forms and Records. Maintenance forms, records, and reports which are to be used by maintenance personnel at all maintenance levels are listed in and prescribed by TM REPORTING OF ERRORS. Report of errors, omissions, and recommendations for improving this publication by the individual user is encouraged. Reports should be submitted on DA Form 2028 (Recommended Changes to DA Publications) and forwarded direct to: Commanding General, U. S. Army Mobility Equipment Command, ATTX: AMSME-MPP, 4300 Goodfellow Blvd., St. Louis, Missouri GENERAL DESCRIPTION The Model FJF-040 fork lift truck is a front loading unit rated to handle loads to 4000 pounds at 24 inch load centers. Pneumatic tires permit satisfactory operation of the truck off paved surfaces Handling of loads is accomplished by engaging the two 40 inch fork prongs with the load. The forks are mounted on a hydraulically operated mast assembly which can raise the load to a height of twelve feet for stacking of commodities handled. The mast is tillable ten degrees rearward to cradle the load when traveling, to three degrees forward to facilitate disengaging the load when depositing it. Travel speed of the trucks is limited to about 12 miles per hour loaded, or 14 miles per hour empty, by an engine speed governor. Steering is power assisted. Arrangement of the controls conforms to general industrial truck standards, permitting ready use by operators with previous fork lift experience. Figure 1-1. Deleted. 1-1
