AERATION TIPS

Should I water before aerating?
Best aerating condition is a soft and moist
ground. If you are unsure of the ground
conditions, as in soil with high clay content, a
simple test will determine whether it is
necessary to water before aerating. Using a
garden hand spade or a large screw driver, you
should be able to drive the tool in the ground 2 to
3 inches with little effort. If you are unable to do
so, then watering the lawn a day before aerating
is necessary.
When should I use the removalole weights?
Soil conditions will dictate whether extra
machine weight is needed for effective coring
action. The weights are provided to give you
added control, and greater tine penetration.

BEFORE YOU START

1. Make sure that engine oil is at engine
manufacturer's recommended level (refer to
engine manual). Be sure gear reduction oil is
at engine manufacturer's recommended level.
Make sure the machine is level when filling
with oil.
2. With the folding handle in its operating
position, lock the handle cam lock (Models
424 & 530A only).
3. Rear wheel control handle must be pulled up
so rear wheels are all the way down.
4 Insert weights if needed.
5. Be sure handle is properly mounted.
Be sure clutch cable is routed properly.
Operating Instructions
CAUTION!
6. Test clutch handle to insure clutch releases
freely.
7. The engine top speed is preset by the engine
manufacturer. Consult the engine
manufacturer's manual for directions to
adjust the governor and carburetor if speed is
not within correct range.
8. 742 Honda Engines Only: The throttle cable
has been installed by the factory, however
throttle spring needs to be connected to
throttle/clutch control lever (see Figure 4).

AERATING

1. Start engine and adjust throttle setting to
provide a comfortable walking speed and
maintain control of the equipment at all times.
2. Adjust depth control knob (see Figure 1 or 2)
to desired depth. Coring depth decreases by
turning the knob clockwise.
NOTE: by raising the rear wheels all the way
up (to obtain maximum coring depth) you will
reduce the unit's stability but increase length
of core.
3. Push down the rear wheel control handle to
lower aerating tines into the ground (rear
wheels will rise).
4. Push down on handle bar for better tine
penetration and maneuverability (front wheel
will rise).
5. Engage clutch control.
6. Adjust engine throttle setting, if needed, for
comfortable speed.
7. To stop, release clutch control.
NEVER cross hard objects or surfaces
(sidewalks, driveways, stepping stones,
etc.) with tines down.
