If the outside temperature is low at the time of the oil change, warm up (to approx.
50°C / 122°F) a part of the new oil and rinse the gear housing with this oil before re-
filling.
Benzol (benzene) or flushing oils too may be used here for rinsing.
Danger of damaging the gear!
Do NOT use petrol (gasoline), petroleum or diesel oil for rinsing here.
Allow the rinsing fluid to drain off completely.
Replace seals (if equipped), reinstall drain screws and tighten them.
Refill with new oil, and let the oil settle.
Check the oil level.
If there is no oil to be seen in the sight glass after the gear has been
refilled with the proper quantity of oil, close the filler neck, start the en-
gine and let the drive rotate for a short while, to bleed the lines free of
air that may be have been trapped.
Reinstall the filler screws and tighten them.
