Troy-Bilt 12001C - Manual (Page 17)

To lubricate the transmission:
5. Place the nozzle of a grease gun on the rim of
the middle hole. Push the nozzle firmly up
against the opening.
6. Apply grease until it begins to come out of the
bottom hole. Replace the bottom plug securely.
Then apply grease to the top plug hole. Add
until it begins to come out of the middle hole.
Reinstall the plugs in the middle and top holes.
7. Reinstall the right-side tines. Before rein­
stalling the tines, use a fine grade of sandpaper
to clean any rust off the tine shaft. Then coat the
tine shaft with a few drops of oii or anti-seize
compound to make future tine removal easier.
ENGINE AIR FILTER
After using your filler for 25 operating hours or
after a 3-month period (more frequently in dirty
or dusty areas), the engine air filter system will
need to be cleaned.
Use the following instructions:
1. Remove the air cleaner outer cover by taking
out the two cover screws shown in Figure 13.
Put cover aside. Remove the thin, outer flocked
filter, the thick foam filter, and the thin, inner
flocked filter. (Your assembly may have one or
two thin flocked filters which need to be
cleaned.) Clean the body of the air filter housing
and the cover with a clean rag.
2. Inspect the flocked filters and thick foam filter
for dirt. If dirty, continue with step 3.
3. Wash the thick foam filter in detergent and
water. 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 oii.
7. The thin flocked filters should be washed in a
water and detergent solution, rinsed thoroughly
in clean water, and air dried. Do not oil them.
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 debris from the
engine cooling fins, around the air intake screen
and levers and linkage. This will help to ensure
adequate cooling and correct engine speed.
SPARK PLUG
Check the spark plug once yearly or every 5
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.
Figure 14: Set spark plug gap at .030“.
