4. Use a bright light inside the element to inspect
for damage. Check the element very carefully
for pin holes or other damage that will allow
dirt to leak through the paper media. Replace
element if necessary.
5. Without removing, visually inspect the condition
of the safety lter for damage or holes. The
safety lter should only be removed for yearly
replacement (or when dirty or damaged).
6. Check the condition and resilience of the radial
sealing surface (inside of the open end) of the
lter. Replace the lter if any cracks, tears, or
other damage to the sealing surface are noted.
7. Use a clean, damp cloth and wipe the interior of
the air cleaner canister clean. Use special care
to clean both the inside and outside surfaces
of the outlet tube.
IMPORTANT: Any dust left on the inside of the
outlet tube will go into the engine and cause
wear.
8. Check the outside surface of the outlet tube for
smoothness and cleanness (this is the sealing
surface).
9. Insert and seat the safety lter and Radialseal™
element carefully into the canister, applying
pressure at the outer rim of the lter; not at the
exible center. Make sure the lter element is
completely in place before installing the cover.
IMPORTANT: DO NOT use the cover latches
to force the lter into the canister -- the cover
should t on with no extra force.
NOTE: DO NOT use petroleum based lubri-
cants on the sealing surfaces of the lter; use
tal cum powder or dry silicone lubricants if re-
quired for lter installation.

10. Install the cover with the word “TOP” properly
oriented to the top of the canister. Give the
cover a slight twist as it reaches the canister to
make sure the tab inside the cover goes into a
slot, otherwise the cover will not t properly.
Make sure both the top and bottom cover
latches are securing the cover in place.

To prevent engine overheating and possible engine
damage, clean grass clippings, chaff, and dirt from
the rotating engine air intake screen after every 8
hours of operation. In certain mowing conditions
(dry grass, leaves, tree “cotton”, etc.), it may be nec-
essary to check and clean the screen several times
each day to prevent engine overheating.
CAUTION
Operating the engine with a blocked air
intake screen, dirty or plugged cooling
ns, and/or cooling shrouds removed will
cause engine damage from overheating.
