4. Setup

Follow these steps to assemble your IKRA IEVL 1840 before its first use.

4.1 Handle Assembly

1. Attach the lower handle bars to the main unit using the provided fasteners.
2. Connect the upper handle bar (with the control switch) to the lower bars. Ensure all cables are securely routed and fastened with the cable clips to prevent damage and ensure proper strain relief.

5. Operating Instructions

Proper operation ensures effective lawn care and extends the life of your machine.

5.1 Adjusting Working Depth

The working depth can be centrally adjusted using the lever on the side of the machine. The depth ranges from +6 mm (for transport/storage) to -12 mm (deep scarification). For aeration, a shallower depth is usually sufficient, while scarification requires deeper penetration to remove thatch effectively.

5.2 Starting and Stopping

1. Connect the machine to a suitable power outlet using a properly rated extension cord. Ensure the cable is secured with the strain relief.
2. To start, press and hold the safety button on the handle, then pull the bail switch towards the handle. Release the safety button once the motor starts.

3. To stop the machine, release the bail switch. The motor will stop, and the rollers will cease rotation after a short delay.

5.3 Scarifying and Aerating

For best results, scarify your lawn in spring and autumn. Aeration can be done more frequently as needed.

• Scarifying: Use the blade roller. Set a depth that allows the blades to penetrate the thatch layer without digging too deep into the soil. Make overlapping passes across your lawn.
• Aerating: Use the tine roller. This process helps to ventilate the soil and improve water and nutrient absorption. A shallower depth is typically used for aeration.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your IKRA IEVL 1840.

6.1 Cleaning

• Always disconnect the machine from the power supply before cleaning.
• Clean the machine immediately after each use.
• Remove grass and debris from the housing, especially around the rollers and air vents, using a brush or cloth.
• Do not use water or high-pressure cleaners directly on the motor or electrical components.

6.2 Collection Bag

• Empty the 55-liter collection bag frequently to maintain optimal performance and prevent clogging.
• Clean the collection bag regularly to ensure proper airflow.
