AERATION TIPS

Operating Instructions

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.

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.

CAUTION!

Be sure clutch cable is routed properly.

CAUTION!

NEVER cross hard objects or surfaces (sidewalks, driveways, stepping stones, etc.) with tines down.

Operating Instructions

THROTTLE CABLE ADJUSTMENT. Model 742 (Honda Engine Only)

1. Start engine and allow it to reach operating temperature.

2. Adjust the throttle cable at the adjuster bracket by turning the adjuster nut. Tightening will increase engine speed, loosening will reduce engine speed.

NOTE: A properly adjusted throttle will slightly increase engine speed as the clutch engages.

• If the clutch engages too soon, the engine will stall.

• If the engine speed is too high, the gradual controlled start is lost.

Figure 6

REAR WHEEL ADJUSTMENT

The rear wheel depth/stability control knob (see Figure 7) allows adjustment for better stability and maneuverability by turning knob clockwise. Adjusting for depth by turning knob counter clockwise determines the length of the cores pulled in the following ways:

(A) The rear wheels can be adjusted to the

level you desire so you can control the penetrationof the tines to within a fraction of an inch. The length of the cores pulled can be controlled accordingly .

(B) With the rear wheels adjusted to the full

up position, you will obtain maximum tine penetration. Pushing down on the machine’s handle bars will put most of the weight of the machine on the tines. In this configuration you will pull the longest cores. (Front wheel will rise).

Figure 7

Operating Instructions

NOTE: Adjusting for greater st ability will shorten the length of the cores you pull. You will gain greater side-to-side stability (see below “Operating on Hills.” Adjustment s for greater stability will also improve maneuverability during aeration.)

TURNING AND MANEUVERING THE AERATOR

Gradual maneuvering while aerating can be accomplished by simply guiding the machine. We recommend that you adjust your engine’s speed control to allow for a comfortable walking speed. This will also help you maintain complete control while working in tight spaces. Adjusting for more stability (with the rear wheels lowered, reducing tine penetration) will make turning easier. When reversing direction or making sharp turns two methods of turning can be used. Select the safest and most comfortable method for the conditions you face:

OPERATING ON HILLS

WARNING!

DO NOT operate on hills exceeding 35%

grade.

Figure 8

(A) Release clutch control handle, pull up rear

wheel control handle, then pivot machine on rear wheels to turn.

(B) Release clutch control handle, lift handle bar

and pivot machine on front wheel.

WARNING!

This method is NOT recommended when

operating on hills. (See next section.)

This unit is not designed to be used on steep slopes. Be aware that when operating on hills the tilt of the aerator will cause the machine’s center of gravity to shift to the downhill side of the machine. Under these circumstances you may experience:

(A) The need to exert a greater effort to steer and maintain the balance of the machine. (B) Uneven tine penetration, when operating across a hill. Due to the shifted center of gravity the downhill tines will penetrate to the maximum depth, while uphill tines may not.

WARNING!

In extreme situations (very steep hills) the machine may be so unbalanced, that it may present the danger of rolling over.

Operating Instructions

When operating on hills you should

consider the following:

(A) Operate the machine up and down the

hills rather than across them.

(B) Use the rear wheel depth/stability control

knob to set the rear wheels for extra stability. This can be a great benefit when you do choose to run the aerator across a hill. An added benefit of using the rear wheel depth control when aerating across a hill is that you will improve the consistency of the cores pulled from the uphill tines when compared to those pulled by the downhill tines.

roll-over risk and maintains consistent core plug length. (See Figure 9)

(D) Remove remaining weight from downhill

side to uphill side after each pass when operating across hills.

WARNING!

NEVER disengage tines from ground when travelling up or down hill. ONLY disengage on flat surface.

TRANSPORTING THE BLUEBIRD AERATOR

MODEL 424

The BlueBird 424 Aerator has three convenient features to assist you in transporting the unit in your pick-up truck, van and even in some car trunks. Those features are: removable weights, a folding handle and convenient lifting handles on the sides of the machine. The features are provided for your optional use and can be of great benefit when required.

Removable Weights

• Unlatch weight locks.

• Grab weight handles and pull the weights

from the machine.

Note: Weight 36 lb/16 kg each.

Folding Handle

• Release handle cam lock.

• Fold handle forward over the engine until it

is resting on the engine guard.

Lifting Handles

Lifting handles are located on both sides of the aerator, to allow two people to lif t the unit.

CAUTION!

Avoid back or muscle injury! Use safe lifting techniques, DO NOT exceed your physical limitatons. DO NOT attempt to lift ALONE. Weight 193 lb/88 kg w/o weights.

Figure 9

MODELS 530A AND 742

The removable weights are for side hill stability and tine penetration as applicable.

CAUTION!

DO NOT lift aerators.

With the weights in place, these models are designed for easy loading and unloading on ramps and trailers. The treaded front wheel provides increased control during transport. Use engine power to load unit.
