MAINTENANCE 24.4 EVERY 50 HOURS SERVICE 24.4.1 DRAIN WATER, SEDIMENT FROM FUEL TANK Loosen valve (1) on the right side of the tank so that the sediment and water will be drained together with fuel. 24.5 EVERY 100 HOURS SERVICE Maintenance for every 50 hours should be carried out at the same time. 24.5.1 CHECK OIL LEVEL IN HYDRAULIC TANK, ADD OIL WARNING When the oil filler cap is removed, oil may spurt out, so turn OFF the engine and wait for the oil temperature to cool down, then turn the cap slowly to release the internal pressure before removing the cap.
If oil has been added to above the H mark, turn OFF the engine and wait for the hydraulic oil to cool down, then drain the excess oil from the drain plug. 1. Lower the bucket horizontally to the ground and turn OFF the engine. Wait for 5 minutes, then check sight gauge (G). The oil level should be between the H and L marks. NOTE: Do not add oil if the oil is above the H line. This will damage the hydraulic equipment and cause oil to spurt out. 2. If the oil is below the L level, open the inspection cover above the step and add oil through oil filler port (F). For specification of the oil to use, see “20 FUEL, COOLANT AND LUBRICANTS ACCORDING TO AMBIENT TEMPERATURE” on page 3-10.
