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 no. 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 authorised Mantis office.
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 no. 12, page 16) 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 no. 43, page
16) 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 no.
22, page 16). Inside the flange
housing, you'll find the clutch
drum (Key no. 57, page 16).
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!

engine sits all the way down on
