adjustment
of the belt tension
may be re-
quired due to normal stretch
and wear on the belt.

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
released
as shown
in figure

nut so that there is only a slight amount
of slack in
the control wire. Tighten
the upper nut against the
bracket.
