5. Place the nozzle of a grease gun onto the rim
of the fill hole. Push the nozzle of the grease
gun against the opening to seal the nozzle of the
gun against the rim of the fill hole.
6. Apply grease into the transmission until
grease begins to come from the air vent hole.
7. Reinstall the fill hole plug and the air vent
screw. Tighten them securely.
8. Reinstall the right-side tines. See “Tine
Removal and Installation,” this Section, for rein­
stallation instructions. Before reinstalling the
tines, use a fine sandpaper to clean any rust off
the tine shaft. Then coat the tine shaft with a
few drops of oil or anti-seize compound to make
future tine removal easier.
ENGINE AIR FILTER
After using your Tiller for 25 operating hours or
after a 3-month period (more frequently in dirty
or dusty areas), the engine air cleaner filter will
need to be cleaned and re-oiled.
Use the following instructions:
1. Remove the air cleaner outer cover by taking
out the two cover screws shown in Figure 13.
Put the cover aside. Remove the optional pre-fil­
ter (if so equipped) and the thicker foam filter.
Clean the body of the air filter housing and the
cover with a clean rag.
2.
Inspect the pre-filter (if so equipped) and thick
foam filter for dirt. If dirty, continue with step 3.
3. Wash the thick foam element in a detergent
and water solution. Squeeze to remove dirt— do
not twist it.
4. Rinse the foam filter in clean water thoroughly.
5. Wrap in a cloth and squeeze until dry.
6. Saturate the foam filter with clean engine oil
and squeeze out any excess oil.

.
If you have the optional pre-filter, it should be
washed in a water and detergent solution, rinsed
thoroughly in clean water, and air dried.
8
. Reassemble all components carefully.
CARBURETOR ADJUSTMENT
Your Tiller is designed to run at full speed
when you are tilling or cultivating with it. When
you release the throttle lever, the engine should
return to its idle speed.
NOTE
The tines may slowly rotate when you have them
out of the soil and the engine is idling.
The tines should stop rotating (when engine is
idling) when you lower the tines into soft soil.
If the tines continue to rotate (when engine is
idling) in soft soil, the idle speed may be set too
high or the centrifugal clutch may be malfunc­
tioning.
If you think your carburetor or the engine
speed require adjustment, see your nearest
Authorized Tecumseh Service Outlet.
Never tamper with the engine governor which
is factory-set for the proper engine speed.
Overspeeding the engine above the factory
high-speed setting can be dangerous.
COOLING SYSTEM
Important
— Frequently remove grass clip­
pings, dirt and debris from the engine cooling
fins, around the air intake screen and levers and
linkage. This will help to ensure adequate cool­
ing and correct engine speed.
SPARK PLUG
Check the spark plug once yearly or every 100
operating hours. Clean around the spark plug,
then remove it for inspection. Replace the plug if
the electrodes (see Figure 14) are pitted or
burned, or the porcelain is cracked.
Check the electrode gap with a wire feeler
gauge and adjust the gap to .030" if necessary.
