CARBURETOR ADJUSTMENT
A
| WARNING
\
If any adjustments are made to the
engine while the engine is running
(e.g.
carburetor),
disengage
all
clutches and tines. Keep clear of all
moving parts and be careful of
heated surfaces and muffler.
Minor carburetor adjustment may be required to
compensate for differences in fuel, temperature,
altitude or load.
NOTE
A DIRTY AIR CLEANER WILL CAUSE
ENGINE TO RUN ROUGH. BE CERTAIN
AIR CLEANER IS CLEAN AND AT¬
TACHED TO THE CARBURETOR
BEFORE ADJUSTING CARBURETOR.
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 left half of the
chain case on its side, add 12 ounces of Plastilube #0
grease and assemble the right half to it. This grease
can be obtained at your nearest authorized dealer.
Order Part Number 737-0133.
MAINTENANCE
ENGINE OIL
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 to insure proper lubrication of inter¬
nal parts. (Take care to remove dirt around plugs.) Be
sure oil level is maintained full to point of overflowing.
See figure 25.
To change oil, remove drain plug and tip the tiller for¬
ward while engine is warm. Replace drain plug.
Remove oil fill plug and refill with new oil of proper
grade as instructed in the engine manual. Replace oil
fill plug.
FIGURE 25.
AIR CLEANER
The air cleaner prevents damaging dirt, dust, etc., from
entering the carburetor and being forced into the engine
and 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 t .
pletely assembled.
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.
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
mowing season; check engine manual for correct plug
type and gap specification.
BELT REPLACEMENT
If belt replacement is required, order belt or belts by
part number from your nearest authorized dealer.
1. Remove the belt cover by removing three self¬
tapping screws. A 3/8" wrench is required. See
figure 26.
