2-Cycle Tiller Maintenance
HOW TO RESEAT THE FLANGE
At some point, you may find that the
tines won't turn when you press the
throttle. This may mean the engine isn't
sitting all the way down on the worm
gear housing.
Perhaps you've been using your Tiller
for several years. Or perhaps you've
removed the engine for use with our
hedge trimmer attachment, then replaced
it. In either case, the flange bolt may
have come loose and lifted the
engine up.
If this happened you'll notice a gap
between the bottom of the engine clutch
case and the top of the worm gear
housing. (Figure 1)
To fix this, loosen the flange bolt. Take
the engine off the worm gear housing.
Notice the hex head on top of the drive
shaft . Inside the clutch case, you'll find
the clutch drum. Make sure the hex head
lines up with the clutch drum inside the
clutch case.
TRANSMISSION CARE
Check the transmission grease level after the first
10 hours of use, then check yearly.
With the tines off, remove the transmission plate
(Figure 3) and gasket to see if the grease level is up
to the plate flange (Figure 4). If it is not, you will need
to add lithium zero or lithium one grease.
Wipe off any excess grease, replace the transmission
gasket and plate.

Then put the engine back on the

plastic carrying handle is not under the
fuel tank.

there will be no gap between the clutch
