2. Open the fuel valve.
3. On a cold engine, move the throttle–choke
control forward to the Choke position.
Note: Do Not use the choke when the engine
is warmed up.
4. Pull the recoil starter handle lightly until you feel
resistance, then pull it sharply. Allow the rope to
return slowly.
5. When the engine starts, move the throttle–choke
control to the Fast position.
Lowering the Tines
DANGER
The rotating tines under the engine deck are
dangerous. Tine contact can cause serious injury
or kill you.
Do Not put hands or feet under the unit when
the engine is running.
1. Push the tine ground engagement lever down and
forward to raise the rear wheels and engage the
tines.
2. Adjust the throttle for the working conditions.
Raising the Tines
Pull up on the tine ground engagement lever to lower
the wheels and raise the tines; significant effort may
be required if extra optional weights have been added.
Stopping the Engine
1. Bring the unit to a full stop.
2. Place the throttle midway between the "SLOW"
and "FAST" positions.
3. Raise the tines.
4. Allow the engine to run for a minimum of 15
seconds, then move the throttle to the (Off)
position to kill the engine.
5. Close the fuel shut-off valve when the machine
will not be in use for a few days, when
transporting, or when the unit is parked inside
a building.
Operating the Self-Propel Drive
The aerator is variable speed, the more you squeeze
the drive bail against the handle the faster the machine
travels.
1. Start the engine.
2. Move the self-propel drive bail from the neutral
position.
• To move forward, squeeze the self-propel
drive bail against the handle (see Figure 9).
1. Reverse-push down and
away from handle
2. Drive bail (neutral
position)
Note: The ground speed can be varied by
increasing or decreasing the distance between
the self-propel drive bail and the handle.
Lower the drive bail, towards the neutral
position, to decrease the ground speed when
making a turn or if the unit is moving too
fast. If the drive bail is released, the drive
bail returns to neutral and the unit stops
self-propelling. Squeeze the ground speed
control bail closer to the handle to increase
the ground speed. When the drive bail is held
tight against the handle, the unit self-propels at
the maximum forward ground speed. Release
the drive bail to stop moving or whenever you
leave the unit.
• To turn left or right, decrease the speed, push
down on the handles, and turn the unit in
the desired direction; then resume normal
operation. The tines can be in the down
position when making gradual turns.
• To move in reverse, release the drive bail and
allow it to return to neutral. Push the drive bail
down and away from the handle. The ground
