To check or add worm gear oil:
1. Remove fill plug.
NOTE
There is a breather in a vent hole
at rear of worm drive housing.
Do not remove breather for any
reason.
2. Oil should be level with plug hole when
tines are resting on ground (housing level).
If not, add special worm gear oil (avail¬
able from your dealer) through plug
hole until full. Do not overfill.
NOTE
Damage to the worm gear drive
which results from use of any
lubricant other than special
worm gear oil as specif iced by
the manufacturer, or its equiva¬
lent, will automatically invalidate
the warranty.
3. Reinstall and tighten fill plug.
NOTE
The worm drive housing may be¬
come quite warm from operation.
This is completely normal and no
harm to gears will occur if the
housing is kept full as specified
with the special worm gear oil.
