2. Use solvent and a brush to wash any oil and dirt off the filler plug, and dry them with compressed air.

3. Remove the filler plug (A) and the sealing washer (B), then check the condition of the fluid, and make sure the fluid is at the proper level (C).

4. The fluid level must reach up the bottom of the filler plug hole. If it is below the hole, add the recommended fluid until it runs out, then reinstall the filler plug with a new sealing washer.
