4. Installing the Rollers
The GE-SA 1435 comes with two interchangeable rollers: a knife roller for scarifying and an aeration roller for aerating. Select the appropriate roller for your task and install it according to the instructions in the separate roller replacement guide (if provided) or by consulting the machine's internal mechanism. The knife roller has 20 stainless steel blades, and the aeration roller has 26 claws.

Operating Instructions
Proper operation ensures effective lawn care and extends the life of your machine.
1. Connecting to Power
Connect the machine's power cord to a suitable outdoor-rated extension cord, and then plug into a grounded power outlet. Ensure the power supply matches the machine's specifications (1400W).
2. Setting Working Depth
The GE-SA 1435 features a 3-stage central working depth setting, ranging from 3mm to 9mm, plus a parking position. Adjust the working depth using the lever located on the side of the machine. For scarifying, start with a shallower depth and gradually increase if needed. For aerating, a moderate depth is usually sufficient.

3. Starting the Machine
Press and hold the safety switch, then pull the operating lever to start the motor. Release the safety switch once the motor is running. The machine will automatically propel itself forward; guide it steadily across the lawn.
4. Scarifying and Aerating Technique
Move the machine in straight, overlapping lines across your lawn, similar to mowing. Avoid staying in one spot for too long to prevent damage to the turf. The collection bag will gather removed thatch and moss. Empty the bag regularly to maintain optimal performance. The machine is suitable for lawns up to 400 m².

Maintenance
Regular maintenance ensures the longevity and efficiency of your Einhell GE-SA 1435.
- Cleaning: After each use, disconnect the power and clean the machine. Remove any grass, soil, or debris from the housing, rollers, and air vents. Use a brush or cloth; avoid using water directly on electrical components.
- Roller Inspection: Regularly inspect the knife roller blades and aeration roller claws for wear or damage. Replace worn or damaged rollers to maintain effective performance. Ensure the rollers are free from tangled grass or roots.
- Storage: For compact storage, fold the push boom as shown in the setup section. Store the machine in a dry, secure location, away from moisture and extreme temperatures.
