safety covers attached to the inside of the drive

Gearbox Oil
the gearbox oil should be changed after the first
20 hours of operation to clear away any debris
inside the gearbox, then changed annually there-
after.
Although it is not necessary to remove the drive
chain cover to access the fill and drain plugs, it is
more convenient to do so (see
figures 29–30).
replace the gearbox oil with 80W–90W gear oil
until it just reaches the fill plug.
