How do you check transmission fluid on a Nissan 50 series forklift?

To check the Transmission Fluid on a Nissan 50 series forklift, first, ensure the forklift is on a level surface and the engine is running. Locate the transmission dipstick, usually found near the transmission case, and remove it. Wipe it clean, reinsert it fully, then remove it again to check the fluid level, which should be within the marked range. If the fluid is low, add the appropriate type of transmission fluid as specified in the forklift's manual.
