How to Check the Grease Level Inside the
Worm Gear Housing
When we built your MANTIS Tiller, we lubricated the worm
gear housing thoroughly.
It is imperative that you inspect the grease level once a year.
Simply remove the cover plate on the worm gear housing.
(Picture 1) Then check to make sure the grease comes almost
to the top of the housing. If it doesn’t, add lithium #0 grease
(Item M9985.) This is the only way to add grease to the worm
gear housing. (Picture 1) To purchase MANTIS grease,
contact your local authorized MANTIS dealer or call our Sales
Department at 1-800-366-6268.
Please do not overfill. Too much grease can create pressure,
which could cause seals to fail or the clutch to slip.

How to Reseat the
Flange
At some point, you may find
that the tines won’t turn when
you press the throttle. This may
mean the engine isn’t sitting all
the way down on the worm gear
housing.
Perhaps you’ve been using
your Tiller for several years. The
flange bolt (Key #12, Page 18)
may have come loose and lifted
the engine up.
If this happened you’ll notice
a gap between the bottom of the
engine flange (Key #43, Page
18) and the top of the worm gear
housing. (Picture 2)
To fix this, loosen the flange
bolt. Take the engine off the
worm gear housing. Notice the
hex head on top of the drive
shaft (Key #22, Page 18). Inside
the flange housing, you’ll find
the clutch drum (Key #57, Page
18). Make sure the hex head
lines up with the clutch drum
inside the flange housing.
Then put the engine back on the
worm gear housing. Make sure the
plastic carrying handle is not
under the engine.
If you’ve followed these steps
properly, there will be no gap
between the engine flange and the
worm gear housing. (Picture 3)
Make sure you tighten the flange
bolt!

doesn’t sit all the way down on the
