MAINTENANCE
Check the Air Filter Often
A wet or dirty air filter can affect the
way your engine starts, performs, and
wears. So, it’s a good idea to check your
air filter once a month.
If you work in dusty soil, or if you
want to be on the safe side — then
check your filter more often (for
instance, before each use). But be sure
to replace it at least once a year, in the
spring or fall. Clean or change it as
needed. It is recommended to change
the air filter yearly.
How to Check, Clean and
Change the Air Filter
1. Loosen the wing nut on the side
of the air-cleaner cover. (See Picture 1,
or look up Key #1 in Air Cleaner Parts
Assembly on page 17.)
2. Take off the cover. Make sure to
clear the choke button. (Picture 2)
3. The air filter is the pad on the
inside of the air-cleaner cover. Check
whether it is soiled or moist.
4. If the air filter needs cleaning or
no longer fits properly, remove it. Just
lift an edge carefully and “peel” it out.

5. Use a brush to remove debris
from the pad.
6. If the air filter is so dirty that it
won’t come clean, you must replace it
or severe engine damage will occur.
Order a new one directly from our
Customer Service Dept. Call 1-800-
366-6268.
7. Insert your clean filter inside the
air-cleaner cover.
IMPORTANT! Make sure filter
is “seated” properly in the
cover. The filter must fit
snugly inside the rim that
holds the filter in place.
Installing the filter incorrectly will
cause engine damage and void the
warranty. Fit the cover back over the air
cleaner. (Again, make sure to clear the
choke button.)
8. Tighten the wing nut to secure the
cover.
Note:
Please check the lip on the Air Cleaner
Cover. If the lip is chipped or cracked,
it should be replaced. This will prevent
dirt from being ingested through the
carburetor into the inside of the engine.

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 9985.) This is
the only way to add grease to the worm
gear housing. (Picture 2) To purchase
MANTIS grease, call your local
authorized MANTIS dealer.
Please do not overfill. Too much
grease can create pressure, which could
cause seals to fail or the clutch to slip.
Fuel Filter Replacement:
Fuel filter to be changed at the end of
every season.
Clear Blockages From
the Fuel Line & Filter:
After you’ve used your Tiller for a few
seasons, check for blockages in the fuel
tank and fuel filter. Such blockages can
keep your Tiller from starting.
Clear any blockages you see in the
tank, fuel filter, or fuel line. Remember:
The fuel filter is located inside the tank.
(See Picture 3) Then use the normal
starting procedure to start your Tiller.
