Never make unnecessary adjustments. The factory
recommended settings are correct for most ap¬
plications.
If adjustments are needed, refer to the engine manual
packed with the tiller.
LUBRICATION
Chain Case
The chain case is pre-lubricated and sealed at the fac¬
tory. It requires no checking unless the chain case is
disassembled. To fill with grease, lay the right half of
the chain case on its side. Add 10 ounces of Plastilube
#0 grease and assemble the left half to the right half.
The grease can be obtained at your nearest authorized
dealer listed on the back of this manuat. Order part no.

MAINTENANCE
A
Disconnect the spark plug wire from
spark plug and ground against the
engine block (secure
in "V" slot)
before performing any maintenance.
See figure 8.
CLEAN ENGINE
Wipe off all spilled fuel and oil. Keep the engine clean
of foreign matter and be sure the cooling fins on the
cylinder are kept clean to permit proper air circulation.
This is an air cooled engine and free flow of air is essen¬
tial to proper engine performance and life.
ENGINE OIL
Check oil level before each use. Be sure oil level is
maintained full to point of overflowing. See figure 19.
FIGURE 19.
Change the oil in the crankcase after the first two hours
of operation of your new engine and after each 25 hours
of use thereafter. This will ensure proper lubrication of
internal parts to prevent excessive wear.
To change the oil, remove drain plug and tip the tiller
forward while engine is warm. See figure 19. Replace
drain plug. Remove oil filler cap, taking care to remove
dirt around filler plug. Refill with new oil of proper grade.
Replace filler cap.
AIR CLEANER
Service the air cleaner every 25 hours of operation. The
air cleaner prevents damaging dirt, dust, etc. from •
entering the carburetor and being forced into the
engine. It is important to engine life and performance.
To service air cleaner, refer to the engine manual
packed with the tiller.
Never run your engine without air cleaner com¬
pletely assembled.
SPARK PLUG
The spark plug should be cleaned and the gap reset
at least once a season or when oil is changed. Spark
plug replacement is recommended at the start of each
season; check engine manual for correct plug type and
gap specification.
