    Note: Wipe the covers and surfaces around openings before you remove the dipstick/fill plug.

  4. Remove the dipstick/fill plugs for both differentials. Fill the differentials with oil. Maintain the oil between the "ADD" mark and the "FULL" mark on the dipstick/fill plug of each differential.

    Reference: Refer to Operation and Maintenance Manual, "Lubricant Viscosities and Capacities (Refill)".

    Note: Make sure that the dipstick/fill plugs are installed completely before you check the oil level. If the dipstick/fill plug is not installed completely, an incorrect oil level reading can occur.

  5. Install the dipstick/fill plugs for each differential. Operate the machine for a few minutes and allow the oil to flow completely through the axles. Remove the dipstick/fill plugs and check the oil level. Add oil, if necessary.

  6. Clean the dipstick/fill plugs and install the dipstick/fill plugs.
