FIGURE 19.
BELT TENSION ADJUSTMENT
Tine Clutch
Periodic adjustment of the belt tension may be required
due to normal stretch and wear on the belt. Adjustment
is needed if the tines seem to hesitate while tilling, but
the engine maintains the same speed.
To adjust, loosen the hex nuts at the cable bracket on
the handle. See figure 20. With the clutch lever re­
leased as shown in figure 14, adjust the bottom nut so
that there is only a slight amount of slack in the control
wire. Tighten the upper nut against the bracket.
NOTE
Do not overtighten control wire.
Too much tension may cause it to
break.

If adjustment is needed, refer to steps 7 and 8 of At­
taching the Drive Control Cables in Assembly In­
structions.
CARBURETOR ADJUSTMENT
At 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. Be careful of heated
surfaces and muffler.
Never make unnecessary adjustments. The factory set­
tings are correct for most applications. If adjustments
are needed, refer to the separate engine manual
packed with your tiller.
LUBRICATION
Chain Cases —The chain cases are pre-lubricated and
sealed at the factory. They require no checking unless
the chain cases are dissassembled. To fill with grease,
lay the left half of the chain case on its side. Add 12
ounces of plastilube #0 grease to the tine chain case
or 10 ounces to the wheel chain case. Assemble the
right half to it. This grease can be obtained at your
nearest
authorized dealer. Order part number
737-0133.
Wheels— Lubricate the wheel bearings with a light oil
after each fifteen hours of operation.
Tine Clutch Control —Lubricate the pivot points on the
clutch levers and the cables at least once a season with
light oil. The controls must operate freely in both
directions.
Pivot Points— Lubricate all pivot points and linkages
at least once a season with light oil.
MAINTENANCE
Ac
WARNING*}
Disconnect the spark plug wire and
ground it against the engine before
performing any repairs or main­
tenance.
IMPORTANT
If for any reason the tines are re­
moved from the tiller, be certain the
tines are reassembled so that the
sharp edge of the tines enter the
soil first. Refer to item number
one under “Operation.”
