   NB: Ensure the bolt goes through the spring.

4. Mount clutch handle and throttle control as shown on the picture.

5. Mount the side guards using the bolts and nuts supplied. Note the side guard must go under the body frame.

6. Mount the blades using the cotter bolts and pins.

7. Mount the depth skid with the cotter bolt and pin.

8. Fit the panel to the handlebar with the 4 screws. (only Lilli 572/575)

Clothing
When using the machine, wear close-fitting work clothes, hard-wearing work gloves, ear defenders and non-slip boots with steel toecaps.

Operating the tiller
Ensure the machine is placed on a level surface with the support wheels lowered prior to start.
Remove all foreign objects from the work area before using the machine. Stones, glass, branches and similar items may damage the tiller. Also, check the bolts on the tiller are tightened.
Start the motor as per the instructions below. Stand clear of the machine’s moving parts.
Never attempt to move the machine in any way other than intended for normal use while the motor is running.

The tiller is designed for use in vegetable gardens and flowerbeds. Ensure that you are familiar with these instructions before operating the machine, in particular the motor start and stop procedures. Fig 9: To use the black handle the control stick must first be activated. By tilting the control stick to the right or left side and then activate the black handle lever, the tiller will move forward or backwards. Pay attention while reversing. It is important that the area is cleared, for any obstacle before reversing. Never reverse the tiller against a wall, tree or any other fixed obstacle.

Operation zone
While the machine is being operated and the motor is running, do not leave the operation zone marked fig 11. If it is necessary to leave the operation zone, for example to attach an accessory, first stop the engine.  It is normally necessary to drive the tiller over a section of earth 2-3 times from different directions. Do not till very wet soil, as clods of earth will form that are difficult to break up.

Adjusting the handle
Lilli 572/575 only: Fig 13. The handle angle can be adjusted. Use the two hand wheels to set one of the 3 available positions. The handle can be flipped forward during transport. NB: Ensure the cables do not become trapped.

Adjusting the wheel/ depth skid
Fig. 14: The support wheels are mounted on the tiller. They can be adjusted to the required height by pulling the lock handle (A) and moving the ring up or down. The wheel ring can be used to stabilise the machine when tilling and help to prevent the machine falling into soft soil.
Fig. 15. The depth skid can be adjusting for tilling in three different depths.The deeper the depth skid sits in the soil, the deeper the tilling blades will work and the slower the machine will advance.The right cultivating depth will lighten your workload.The correct tilling depth depends on the soil, and we recommend you make several attempts to see how deep the depth skid should be so that you can work optimally in your soil. To adjust the depth skid, pull it backwards and up till the preferred height is found.Place the depth skid vertically, and it will fall into a notch.

Lubrication of gearbox
The gearbox is permanently lubricated at the factory, never open the gearbox.

Starting and stopping the engine

Remember: Always check the oil level prior to use!
The oil level must always be between the min. and max. Mark on the dipstick. Always use SAE-30 oil. Use only unleaded E5 gasoline. Never over-fill the gas tank. Warning: Stay out of dashed zone, while starting the engine! Always start the engine from dotted operation zone. See fig. 12.

Starting the engine See fig. 10

1. Set the throttle control (C) on the handle to max.
2. Position the choke at max. Move the choke lever fully to the left. The choke is not required if the motor is hot.
3. Pull the start cord to start the motor. Always feed the start cord back into the motor by hand.
4. When the motor is started, set the choke to minimum (fully to the right) Engage the throttle slightly.

Stopping the engine

1. Set the throttle control to “low” and let the motor run for approx. 30 seconds.
2. When the motor idles, set the throttle control to full stop.

Vibrations may travel up into the handle during use. We therefore recommend taking a break every 30 minuttes.

Important – Adjustment of clutch cables before use:

1. Start the engine on tiller and lift the blades, so they don’t touch the ground.
2. Activate the clutch handle slowly (forward and reverse) to find the point where blades start to turn around – and then at that point measure the distance between grip and outer plastic handle. See fig. 16+17.

It is recommended to be 2 persons doing this: One that holds the tiller and activate clutch handle and one that adjust the cables.

Forward:
The forward belt should first be activated (blades start to rotate), when the clutch handle is 80 mm above the grip. Then the belt will not slide on the pulley.

Reverse:
The reverse belt should first be activated (blades starts to rotate), when the clutch handle is 30 mm above the grip. This to avoid that the reverse belt is too tight and being activated unintendedly and thereby becomes warm and risks to shrink.

If the belt is activated with a different distance, adjust the clutch cable for forward and/or reverse by following this procedure: The clutch cable can be adjusted both on the clutch handle or behind the belt cover on machine. See fig.18+19.  It doesn’t matter which place to tighten it.

1. Loosen the nut (A)
2. Adjust the bolt (B):
   • Clockwise will loosen the cable (+)
   • Anti-clockwise will tighten the cable (-)
3. Find the right adjustment to get the recommended distance between grip and handle
4. Tighten the nut (A)

Cleaning the tiller
The tiller should be cleaned after use. Use a garden hose to wash off soil and dirt. Remove any grass, etc. from the rotor shaft. The chassis number should only be cleaned with a damp cloth to avoid unnecessary wear. Avoid using a highpressure washer during cleaning

Changing the oil
The oil should initially be changed after the first 5 hours of use, and thereafter once per year.

1. Let the motor run for 5 minutes to heat up the oil. This allows the oil to run more freely and makes for a more complete oil change.
2. After 5 minutes, stop the motor. Remove the spark plug cap. Drain the oil by unscrewing the sump plug. Remember to drain the oil into a container of sufficient capacity. NB: The motor must not be tipped backwards more than 45 degrees.
3. Screw the sump plug back in and pour new oil into the motor. Do this by removing the dipstick and pouring in the recommended quantity of oil.
4. Refit the spark plug cap.

Alternatively, use an oil extractor kit.

1. Suck the oil up through the oil filler hole using the syringe. Use the hose to reach the sump.
2. Transfer the used oil to the container.
3. Fill the engine with new SAE-30 oil.
4. Check the oil level using the dipstick.

Air filter maintenance
Please inspect and clean the air filter on a regular basis. If the filter has not been cleaned for a longer period, this will have influence on the engines power take-off and the  exhaustion.

1. Clean around the air filter before it is removed.
2. Carefully remove the paper filter and check it. Clean it with a soft brush. If it is very dirty, it must be changed. Take care that no dirt gets into the intake of the engine.
3. Wash the black foam element on the right side in warm soapy water.
4. Press the water out of the foam element and let it dry. Put a few drops of SAE-30 oil on the filter to moisten it lightly with oil. Carefully squeeze out any surplus oil. Remount the element.
5. Check that all parts are fitted correctly, and the cover closed as shown in the picture.

Spark plug maintenance

• Remove the spark plug cap.
• Brush away any dirt and deposit of the spark plug.
• Loosen the spark plug using a spark plug socket.
• Check the insulation is intact.
• Clean the spark plug using a wire brush.
• Measure the electrode gap 0.7–0.8 mm. Avoid damaging the electrode.
• If it is damaged, replace it with a new one.
• Refit the spark plug.
• Refit the spark plug cap

Storage

• If the machine is likely to be stored unused for prolonged periods, follow the instructions below. This will ensure longer machine lifetime.
• Use a garden hose to wash off soil and dirt. Remove any grass, etc. from the rotor shaft. The chassis number should only be cleaned with a damp cloth to avoid unnecessary wear. Avoid using a high-pressure washer during cleaning.
• Wipe the tiller with a damp cloth so that all surfaces are clean. Wipe the surfaces down with an oily cloth to prevent rust.
• Always store the machine in a dry, clean location.
