connection, use a 5/16" x 1" bolt and a 5/16" hex
lock nut, not spacers. For holes to the left of the
storage slot (front view), use the 5/16" x 1-3 / 16"
hex bolt, two 1/4" spacers per bolt, and the 5/16"
hex lock nut.
Tighten all onne tions.

smaller opening in the wheel holder using the 5/16" x 1-3
/ 16" screw and the 5/16" lock nut that you pre-assem-
bled in step 2. Attach the lifting handle to a larger hole
using a 5/16" x 1-3 / 16" hexagonal bolt, spacer and

Step 11: Adjust handle and tighten onne tions
Place the lawn aerator right side up on the wheels and lock the lifting handle into the offset at the front
of the storage slot. Perform the following steps to ensure correct alignment of the lifting handle with the
slot.
1. Adjust the compartment from side to side
so that the lifting handle rests on the
right side (seen from behind) of the off-
set on the front of the slot.
2. Align the side plates and then tighten the
eight screws at the corners of the com-
partment. Make sure that the lifting han-
dle is still on the right side of the slot off-
set.
3. Align the middle rail and tighten the two
screws that secure it to the tongue.
Make sure that the lifting handle is still on the
right side of the slot offset. You should bring the handle into alignment with the slot when lowering the
lawn aerator. The locking device is designed to help prevent the handle from slipping out when the
lawn aerator is in use. But if you feel that this part does not fit correctly, simply remove the pin.

OPERATION
Aeration involves pulling small cones, up to three centimeters long, out of the ground to cre-
ate small reservoirs that bring oxygen, fertilizer and water to the roots. For optimum perfor-
mance, the following lawn preparations and operating procedures are recommended.
ATTENTION: THE TIPS OF THE FAN BLADES ARE SHARP. CAUTION DURING USE.
1. Mow lawn and remove loose cuttings before using the lawn aerator.
2. Start the engine with the gearbox in neutral position and set the engine speed to a low
value.
3. Lower the gear lever to the lowest possible speed and the fan so that the fan blades can
penetrate the ground. Increase the speed only if conditions allow.
4. Drive on the lawn in straight, overlapping lanes to increase the ventilation capacity.
5. Avoid extremely sharp bends with blades embedded in the ground to avoid damage to
the lawn.
6. DO OT cross paths or roads without first switching the lawn aerator to the transport po-
sition.
7. Always drive on slopes and inclines from above or below. DO OT try to drive along the
slope.
8. To increase the penetration depth of the fan blades, up to 220 kg of weight such as sand
bags or concrete blocks can be placed on the tray. The weight can be attached to the
shelf with cable ties or straps attached to the front and back of the shelf. Fasten the
straps or ropes so that they cannot get caught in the rotating parts.
9. If the soil is extremely hard and dry, it is recommended that it is watered for up to two
hours before aeration.
10. Do OT try to ventilate if the ground is too wet (muddy).
11. Small stones and pebbles that come to the surface through ventilation should then be
collected so that other equipment, such as lawn mowers are not damaged.
ATTENTION: TO AVOID INJURY, DISCONNECT THE AERATOR FROM THE TRACTOR WHEN
LIFTING OR LOWERING THE FAN BLADES.

MAINTENANCE
1. Knife tips can be sharpened regularly with a small grinder to maintain good penetration.
Tips should be removed to sharpen them. Follow the original angle and contour of the
tips as you grind.
2. Before storage, clean the aerator and lightly oil exposed metal parts to prevent rusting.
LUBRICATION
1. Oil the coil units and the shaft as required.
2. Oil the wheel as required.
