2. Grass Collection Bag Assembly
Assemble the 30-liter grass collection bag according to the instructions provided with the bag components. Once assembled, hook the grass bag onto the rear discharge chute of the lawn mower.
3. Regolazione dell'altezza di taglio
The cutting height can be adjusted between 30 mm and 60 mm. Locate the height adjustment mechanism, typically near the wheels or under the mower deck. Follow the markings to select your desired cutting height. Ensure all wheels are set to the same height for an even cut.
Istruzioni per l'uso
1. Collegamento all'alimentazione
Ensure the mower's power switch is in the "OFF" position. Connect the power cord to a suitable outdoor extension cord, and then plug the extension cord into a grounded outdoor power outlet. Always use an extension cord rated for outdoor use and appropriate for the mower's power requirements (1300W).

2. Avviamento del tosaerba
To start the mower, press and hold the safety button, then pull the operating lever towards the handle. Release the safety button once the motor starts. To stop the mower, release the operating lever.
3. Tecnica di falciatura
- Mow in overlapping rows to ensure an even cut.
- Evitare di sovraccaricare il motore non tentando di tagliare erba eccessivamente alta o bagnata in una sola passata.
- For very long grass, it is advisable to make two passes, setting a higher cutting height for the first pass and then lowering it for the second.
- Always push the mower forward; do not pull it towards you.
- Be mindful of the power cord's position to prevent accidental cutting.

Manutenzione
Regular maintenance ensures the longevity and safe operation of your Dedra DED8740 Electric Lawn Mower. Always disconnect the power supply before performing any maintenance.
1. Pulizia
- After each use, clean the exterior of the mower with a damp panno. Non utilizzare detergenti aggressivi o solventi.
- Remove grass clippings from the underside of the mower deck and around the blade using a brush or scraper.
- Ensure the air vents are clear of debris to prevent overheating.
2. Cura della lama
Periodically inspect the cutting blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and may cause excessive vibration. If necessary, have the blade sharpened or replaced by a qualified service technician. The mower uses a 320mm cutting blade.
