Komatsu operator manual OM010 puts the factory's own answers on record for 36 FG and FD forklift truck variants, gasoline FG20-8 through diesel FD45S-4, in 70 pages running break-in to storage. Service data tables cover fan belt deflection, spark plug gap, valve clearance, and tire air pressure, while the lubrication chart maps every grease point from lift chain to differential. Maintenance and replacement checks fill roughly the back half of the book, with intervals for engine oil, hydraulic tank, transmission, and air cleaner gathered in one table you can post by the workbench. Fill the hydraulic tank on a 20, 25, or 30 chassis to 38 liters; a 4D95L engine takes 7.0 liters of oil at a change. Hours disappear while a parked truck waits on an answer. The scan is bookmarked chapter by chapter, and the consumable parts section means your next order carries the right part number the first time.
