Gearbox
The gearbox is almost maintenance-free, but should be
checked quarterly to be sure that the oil level is main-
tained at half full. A high quality gear oil with a viscosity
index of 80W or 90W and an API service rating of GL-4
or -5 is recommended for use in the gearbox. Oil
should be changed after the first 30 hours or 30 days of
operating. Then, normal change should be adequate.
In the case of seasonal usage, it is best to change the
oil at the end of the season to remove moisture and
corrosive contaminants.
