2. Opladning af batteriet
The mower is powered by a 28V 4Ah rechargeable lithium-ion battery. Before first use, ensure the battery is fully charged. Connect the charger to the mower's charging port and then to a standard electrical outlet. The charger indicator light will change to indicate charging status (e.g., red for charging, green for fully charged).
Note: Do not overcharge the battery. Refer to the charger's specific instructions for charging times. The battery is built-in and not removable for charging.

3. Attaching the Grass Catcher or Rear Discharge Chute
The mower includes a detachable 10.6-gallon grass catcher for collecting clippings. To attach, lift the rear discharge flap and hook the grass catcher onto the mower's frame. For rear discharge without collection, ensure the rear discharge chute (MJ401E-DCA) is properly installed.

3. Klippeteknikker
For optimal results, mow in straight, overlapping lines. Avoid cutting wet grass, as it can clog the mower and reduce cutting efficiency. For tall grass, it is recommended to make two passes, raising the cutting height for the first pass and lowering it for the second.

Opretholdelse
Regular maintenance ensures the longevity and optimal performance of your lawn mower. Always remove the safety key and disconnect the power source before performing any maintenance.
1. Rengøring af plæneklipperen
After each use, clean grass clippings and debris from the mower deck, blade, and grass catcher. Use a brush or cloth; avoid using water directly on electrical components.
2. Blade Inspection and Care
Periodically inspect the steel blade for sharpness and damage. A dull or damaged blade can lead to poor cutting performance and strain the motor. If necessary, have the blade sharpened or replaced by a qualified service technician. Always wear heavy-duty gloves when handling the blade.
