5 OPERATION

5.1 DAILY INSPECTION________________________________________________________

1. Perform a visual inspection of the entire unit, look for

signs of wear, loose hardware, and missing or

damaged components. Check for fuel or oil leaks to

ensure connections are tight and hoses and tubes

are in good condition.

2. Check the fuel supply, radiator coolant level,

crankcase oil and air cleaner indicator. All fluids

must be at the full level mark with engine cold.

3. Make sure all aerator tines are adjusted properly.

4. Check tires for proper inflation.

5. Test the operator back-up system.

Note: For more detailed maintenance information,

adjustments and maintenance/lube charts, see the

Parts & Maintenance manual.

5.2 OPERATING PROCEDURES_________________________________________________

1. Under no circumstances should the engine be

started without the operator seated on the aerator.

2. Do not operate aerator or attachments with loose,

damaged or missing components. Whenever

possible aerate when grass is dry.

3. First aerate in a test area to become thoroughly

familiar with the operation of the aerator and control

levers.

4. Study the area to determine the best and safest

operating procedure. Consider the height of the

grass, type of terrain, and condition of the surface.

Each condition will require certain adjustments or

precautions.

5. Never direct discharge of material toward

bystanders, nor allow anyone near the machine

while in operation. The owner/operator is

responsible for injuries inflicted to bystanders and/or

damage to their property.

6. Use discretion when aerating near gravel areas

(roadway, parking areas, cart paths, etc.). Stones

discharged from the implement may cause serious

injuries to bystanders and/or damage the

equipment.

7. Disengage the drive motors and raise the tines

when crossing paths or roadways. Look out for

traffic.

8. Stop and inspect the equipment for damage

immediately after striking an obstruction or if the

machine begins to vibrate abnormally. Have the

equipment repaired before resuming operation.

9. Slow down and use extra care on hillsides. Read

Section 5.7. Use caution when operating near drop

offs.

10. Look behind and down before backing up to be sure

the path is clear. Use care when approaching blind

corners, shrubs, tress or other objects that may

obscure vision.

11. Never use your hands to clean aerating units. Use a

brush to remove grass clippings from the tines.

Tines are extremely sharp and can cause serious

injuries

CAUTION

The daily inspection should be performed only when

the engine is off and all fluids are cold. Lower aerators

to the ground, engage the parking brake, Stop engine

and remove ignition key.

CAUTION

a new area cautiously. Always operate at speeds that

allow you to have complete control of the aerator.

WARNING

Before you clean, adjust, or repair this equipment,

always disengage all drives, lower implements to the

ground, engage parking brake, stop engine and

remove key from ignition switch to prevent injuries.

OPERATION 5

5.3 STARTING________________________________________________________________

IMPORTANT: Do not use starting assist fluids. Use of

such fluids in the air intake system may be potentially

explosive or cause a “Runaway” engine condition and

could result in serious engine damage.

1. The operator MUST be in the seat and the direction/

speed control pedal MUST be in the NEUTRAL

position.

a. If aerator head is lowered, check to make sure

the area around the aeration mechanism is clear,

then depress aerator lift pedal to the RAISED

position, and turn engine over with starter.

b. Follow starting procedures in the engine owner’s

manual.

5.4 STOPPING / PARKING______________________________________________________

To stop:

Remove your foot from traction pedal. The aerator will

automatically brake when the traction pedal returns to

neutral.

To park the aerator under normal conditions:

1. Raise the aerator heads and move away from the

area of operation.

2. Select a flat and level area to park.

a. Release traction pedal to bring the aerator to a

complete stop.

b. Disengage all drives, lower implements to the

ground, reduce throttle to slow and allow engine

to operate at no load for a minute.

3. Engage parking brake, stop the engine and always

remove the ignition key.

If an emergency arises and the aerator must be parked in

the area of operation, follow the guidelines outlined by

the grounds superintendent. If the aerator is parked on

an incline, chock or block the wheels.

WARNING

NEVER start the unit with the aeration head lowered (the aeration mechanism is automatically engaged when the

head is lowered). If there is something caught in the aeration mechanism, clear the obstruction before attempting to

start the engine.

Any warning decal that becomes illegible should be replaced immediately.

Gasoline is extremely flammable and highly explosive under certain conditions. ALWAYS stop engine and do not

smoke or allow open flames or sparks when refueling.

ALWAYS run unit engine where there is plenty of fresh air to prevent a buildup of carbon monoxide fumes. Carbon

monoxide is colorless, odorless and deadly. NEVER run unit in an enclosed space where exhaust fumes will

collect.

NEVER use the unit in, or near an area where there is dust or fumes in the air which are explosive. The electrical

and exhaust systems of this unit will make sparks which can ignite explosive materials.

DO NOT place hands or feet beneath unit at any time.

Never carry any passengers. This unit is designed to carry only the operator, in the seat provided from the factory.

Use extreme care when backing unit, DO NOT back unit with aerator in DOWN position.

DO NOT place foot on directional/speed pedal when starting engine.

ALWAYS keep arms and legs inside unit while it is moving.

DO NOT leave unit with engine running or keys in ignition.

5 OPERATION

5.5 TO DRIVE / TRANSPORT ___________________________________________________

Read and follow all safety notes contained in this manual

when driving or transporting aerator. Refer to Section 5.2

for general operating instructions. When operating in

reverse look behind you to ensure you have a clear path.

Important: If this aerator is driven on public roads, it

must comply with federal, state and local ordinances.

Contact local authorities for regulations and equipment

requirements.

1. Disengage all drives and raise aerator heads to the

transport position when driving to and from the area

of operation.

2. Disengage parking brake and move throttle lever to

“Fast”. Depress traction pedal slowly.

5.6 AERATING _______________________________________________________________

Drive unit to location to be aerated. To prevent turf

damage, advance throttle to wide open position and start

at slow forward speed before lowering the aerator frame.

When aerator is fully down, the foot speed control should

be pressed firmly against the speed control stop to

maintain constant spacing. After a short run, check hole

spacing to calibrated handle. Adjust as required to be

sure calibrated handle is same as actual hole spacing.

Unit may be turned while aerating. Hole spacing will vary

during turning radius. After eight (8) hours of use, check

roller chains for proper tension. Adjust as required.

5.7 HILLSIDE OPERATION _____________________________________________________

The aerator has been designed for good traction and

stability under normal aerating conditions; however, use

caution when operating on slopes, especially over rough

terrain or when the grass is wet. Wet grass reduces

traction and steering control.

1. Always aerate with the engine at full throttle but

reduce forward speed to maintain the proper aerating

frequency.

2. If the aerator tends to slide or the tires begin to

“mark” the turf, angle aerator into a less steep grade

until traction is regained or tire marking stops.

3. If aerator continues to slide or mark the turf, the

grade is too steep for safe operation. Do not make

another attempt to climb, back down slowly.

4. Correct tire pressure is essential for maximum

traction

CAUTION

To prevent tipping or loss of control, travel at reduced

speed when making turns.

WARNING

DO NOT leave the seat UNLESS the aeration head is

UP and the direction/speed control pedal is in the

NEUTRAL position or the engine will stop. This may

result in personal injury and/or turf damage.

WARNING

To minimize the possibility of overturning, the safest

method for operating on hills and terraces is to travel

up and down the face of the slope (vertically), not

across the face (horizontally). Avoid unnecessary

turns, travel at reduced speeds, stay alert for hidden

hazards, and drop offs.

CAUTION

Do not operate this aerator on slopes greater than

13°.

! !

WARNING

To prevent serious injuries, keep hands, feet and

clothing away from aerating unit when the tines are

moving.

NEVER use your hands to clean aerating units. Use a

brush to remove grass clippings from tines. Tines can

be sharp and could cause injuries.

To clear obstructions from aerating unit, raise areator

heads, engage parking brake, stop engine and

remove key from ignition switch then remove

obstruction.

OPERATION 5

5.8 TOWING / TRAILERING _____________________________________________________
