How to Check the Grease Level
Inside the Worm Gear Housing
When we built your Mantis
added Lithium EP #0 grease to properly
lubricate the transmission for the first 10
hours of operation. As part of the regular
maintenance of your tiller, it is imperative
that you inspect the grease level and add
grease if necessary. This will help your
tiller give you years of excellent usage.
You will need to add grease with a
grease gun using the fitting at the front of
the transmission (Figure 1). You should
add grease through this fitting after the
first 10 hours of operation and then every
50 hours of use.
You can use Lithium EP#0 EP#1
Premature transmission failure can
occur if proper grease level is
not maintained
grease or #2 grease in combination with
specially formulated Mantis
9985).
The following are different service steps
for different type of grease.
IF YOU USE Lithium EP #1 or #0
grease:
1. Make sure the tiller is turned off and
remove the tines.
2. Place the tiller front side down on an
elevated surface and remove the 4
screws holding the transmission cover
(Figure 2).
3. Remove the transmission cover and
gasket. Inspect the grease level. If it
is below the edge of the gear housing,
you will need to add grease. If it is
already flush with this edge, you do
not need to add grease.
4. If grease is needed, remove the
protective cap from the grease fitting,
attach the grease gun, and slowly add

grease until the level is flush with the
edge of the transmission (Figure 3).
5. Return the grease fitting protective
cover, gasket and attach transmission
cover with the 4 original screws.
IF YOU USE Lithium EP #2 grease
in combination with Mantis
(p/n 9985):
Follow steps 1 through 3 and then follow
instructions below.
4. If grease is needed, remove protective
cap from the grease fitting on the front

grease (p/n
of the transmission and attach the
grease gun. Please pay attention to
the size of the grease gun. Different
guns distribute different amount of
grease per pump.
a. If you are using Mini grease gun
with 3 ounce cartridge add 5
full pumps of grease. One pump
from Mini grease gun is equal to
approximately 0.012 oz. or 0.3
grams.
b. If you are using standard
automotive grease gun with 14
ounce cartridge, add 2 full pumps of
grease. One pump from a standard
automotive grease gun is equal to
0.03 oz. or 0.9 grams.
CAUTION: DO NOT ADD MORE
GREASE THAN SPECIFIED ABOVE
5. Remove the grease gun from
the grease fitting and replace the
protective cap.

6. Inspect the grease level. If it is below
the edge of the gear housing, you will
need to add grease. If it is flush with
the gear housing do not add grease.
7. If you need to add more grease,
utilize the specially formulated Mantis
grease (p/n 9985). This grease is
compatible with the grease that was
in the transmission from the factory.
DO NOT USE Lithium EP #2 IN THIS
STEP. (Figure 4)
8. Return the gasket and the
transmission cover. Secure cover with
the 4 original screws.
Always inspect the gasket prior to re-
installation. If the gasket is damaged,
replace it with a new gasket (p/n 436)
DO NOT OVERFILL.
Too much grease can create
pressure which can cause seals
to fail or the clutch to slip.
In between adding grease with the
grease gun, you should inspect the
grease level after approximately 10
hours of operation. If grease is needed,
you can add grease directly to the
opening in the transmission using
Mantis ® p/n 9985.
