(1) Transmission oil filler cap
(2) Transmission oil level gauge
Remove transmission oil filler cap (1). The transmission oil filler cap is located near the articulation joint on the left-hand side of the machine.
Fill the transmission with oil. Reference: Refer to Operation and Maintenance Manual, "Capacities (Refill)" for the proper amount of oil.
Transmission oil level gauge (2) is located on the left-hand side of the transmission below the transmission oil filler cap and oil filler tube. Check the transmission oil level. The transmission oil level must be visible in the transmission oil level gauge before you start the machine. Note: The oil level varies significantly when the engine is stopped from when the engine is running. The oil level will be considerably higher than the operating range when the engine is stopped. The oil level should be above the middle of the gauge before the engine is started.
Clean the filler cap and install the filler cap after enough transmission oil has been added to the transmission in order to start the engine.
