Trim the drive in as far as possible. Check the oil level
is between the MAX and MIN markings on the oil con-
tainer. Top up if necessary using ATF oil. Cleanliness
is extremely important, no dirt must get into the drive
when topping up with oil.
If the system has been drained, fill with new oil and
trim the drive in and out 6–10 times to vent the system.
Check the oil level and top up if necessary.
