Checking for Oil Leaks
Regularly check your tiller for
oil leaks from the engine and the
transmission. Slight seepage is no
cause for major concern. How­
ever, if your tiller is losing a lot of
oil, do not use it until it’s repaired.
Inspect the area where you park
your tiller for stains on the floor
which would indicate a leak. If
you find a leak, first tighten any
bolts or screws which may have
loosened up.
If you are unsure how much oil
has been lost from the tiller, check
the oil levels before operation.
Also, when operating your tiller,
frequently check the oil levels to
be sure that engine oil and trans­
mission gear oil levels don’t be­
come too low for safe operation.
If you have further problems
with oil leaks, contact our
Technical Service Department for
assistance.
Air Cleaner Maintenance
Your tiller’s engine is equipped
with a replaceable dry paper filter.
Replace this filter every 50 operat­
ing hours or at least once a year,
more frequently under dusty or
dirty operating conditions.
Do not attempt to clean this fil­
ter. Simply replace it when dirty.
To Remove Paper Air Filter:
1. Loosen the two screws that se­
cure the air cleaner cover to the
base of the air cleaner.
2. Slightly turn the cover counter­
clockwise. Remove the cover and
the paper air filter.
To Change the Paper Air Filter:
1. Thoroughly clean the base of
the air cleaner and the inside of the
air cleaner cover.
2. Place the new paper filter in the
cover.
3. Place the cover (with filter in­
side it) on the base of the air
cleaner. Align the two screw holes
in the cover with the two screws in
the base of the air cleaner. Refer
to Photo 5-9.
4. Turn the cover slightly clock­
wise and tighten the two screws.

Engine Cooling System
Maintenance
Frequently inspect the engine
cooling fins, shrouds, and throttle
linkage for a build-up of dirt, dried
weeds, grease, etc.
Always keep these areas free
from debris to keep air currents
flowing freely. See Photo 5-10.

Engine Ignition System
Maintenance
Your tiller’s engine has a de­
pendable, maintenance-free elec­
tronic ignition system. The system
has no condenser or points. This
means you do not have to tune up
the engine. The only ignition sys­
tem maintenance required is peri­
odic changing of the spark plug.
(See the following spark plug in­
structions.)
Spark Plug Maintenance
Check the spark plug at the be­
ginning or the end of each season,
or every 50 operating hours.
Clean the area around the spark
plug hole before removing the
spark plug.
1. Stop the engine, and wait for all
moving parts to stop completely.
2. Disconnect the spark plug wire
from the spark plug.
3. Use a 13/16" spark plug socket
to remove the spark plug. The
plug may be cleaned (do not sand­
blast or wire-brush it), and the gap
set at .030" or a new spark plug
may be used instead.
4. Install a new plug if the old
plug’s electrodes are pitted or
burned or if the porcelain is
cracked. See the Engine Manual
for spark plug specifications.
Carburetor Adjustments
Your carburetor has been pre-set
at the factory for best tiller perfor­
mance. If your carburetor may
need adjustment, contact your
nearest authorized engine dealer.
