BELT TENSION ADJUSTMENT
Proper belt tension is critical to good performance. After
1/2 hour of operation, all cables may have to be adjusted
due to initial stretch. Thereafter, check tension after every 2
hours of operation.
TO INCREASE BELT TENSION
1. Loosen upper jam nut. Turn nut up cable in 1/8" increments.
2. Tighten lower jam nut.
3. Check adjustment. With clutch lever engaged, spring
length should be 0.8 inches (20 mm).
TO DECREASE BELT TENSION
1. Loosen lower jam nut. Turn nut down cable in 1/8" increments.
2. Tighten upper jam nut.
3. Check adjustment.
This procedure can be repeated until conduit adjustment
bolts are fully adjusted. If no more adjustment can be
made, belt may have to be replaced.

Tilling Tips
The key to successful tilling is to begin with a shallow cut
on the first pass, and then work an inch or two deeper on
each successive pass.
• Tilling depth will vary with ground conditions.
• When beginning to till in unbroken ground or in extremely
hard soil, set the pin in the highest hole of the drag bar
(follow instructions under Tilling section). This will allow
for shallow tilling. With the drag stake in this position,
make several light passes over the area to be tilled. Reset
for deeper depths with successive passes.
• If tiller jumps or skids uncontrollably, lower the drag
stake by placing the pin in a higher hole. This will allow
for shallower tilling. Hold firmly to the handlebars to
control sudden lurches.
• If weeds, tall grasses, vines, or other materials clog or
jam the tines, reverse the tiller to unwind vegetation.
WARNING
Immediately release the clutch lever if the tines jam or you
strike a foreign object. With clutch lever in neutral position,
stop the engine. Disengage the spark plug wire. When
tines have stopped, remove foreign objects and check for
damage.
K
Cultivating Tips
If you plan to use your tiller for cultivating:
• Plant rows on 20" - 22" centers for ease of turning.
• Set the drag bar with the pin in one of the higher holes. This will allow for shallow cultivation necessary to
turn over weeds, and break up and aerate the soil.

WARNING
Extreme caution must be taken in selecting tilling depth. If you
attempt to till too deeply for soil conditions, that is, with the drag
bar in too high a position, loss of control could result.
When removing material from the tines, stop engine and
remove spark plug wire first.
