1. Ensure that the forklift is parked appropriately, with the parking brake engaged.
2. Locate the transmission fluid dipstick under the seat.
3. Clean the dipstick with a rag.
4. Reinsert the dipstick fully and wait a few seconds.
5. Remove the dipstick and check the transmission oil level. The fluid level should fall between the "Full" and "Add" markers.
6. If the transmission fluid level is low, add enough fluid until it reaches the "Full" mark on the dipstick. Use the recommended transmission oil for your forklift.
