Periodic adjustment of the belt tension may be re-
quired 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 samespeed.
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 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.

sealed at the factory. They require no check-
ing unless the chain cases are dissassembled. To

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 authorizeddealer.
