3. Oppsett
Before operating your Ariens lawn mower, ensure it is properly set up and all initial checks are performed.
3.1 Utpakking og første montering
Your mower may arrive mostly assembled. Carefully remove it from the packaging. Unfold the handle and secure it in the operating position according to the instructions provided in the separate assembly guide (if applicable).
3.2 Fylle på drivstoff
- Sørg for at motoren er av og avkjølt.
- Bruk fersk, ren, blyfri bensin med et oktantall på 87 eller høyere.
- Fill the fuel tank slowly to prevent spills. Do not overfill.
- Sett tanlokket godt på plass.
3.3 Checking Engine Oil
The Briggs & Stratton EXI engine is designed to never require an oil change. However, it is crucial to check the oil level before each use, especially the first use. Add oil if the level is below the 'Full' mark using the recommended oil type (refer to the engine manual for specifics).
3.4 Attaching the Bagger (Optional)
If you intend to bag clippings, lift the rear discharge door and hook the bagger onto the mower frame. Ensure it is securely seated to prevent clippings from escaping.

4. Bruksanvisning
Follow these steps for safe and effective operation of your Ariens lawn mower.
4.1 Starte motoren
- Sørg for at drivstofftanken er fylt og at oljenivået er riktig.
- Stand behind the mower, grasp the bail lever (operator presence control) and pull it towards the handle.
- Pull the starter rope firmly and smoothly until the engine starts. The Briggs & Stratton ReadyStart system typically eliminates the need for priming or choking.
4.2 Stoppe motoren
Release the bail lever. The engine and blades will stop automatically.
4.3 Engaging the Reflex Drive System
To engage the self-propel feature, push the Reflex Drive handle forward. The speed is variable, allowing you to match the mower's pace to your walking speed (1 to 4 MPH) by adjusting how far you push the handle. Release the handle to disengage the drive.
4.4 Justering av klippehøyde
The mower features a 7-position height adjustment system. Locate the height adjustment levers on each wheel. Pull the lever outwards and move it to the desired notch for your preferred cutting height. Ensure all wheels are set to the same height for an even cut. The cutting height ranges from 0.25 inches to 18 centimeters (approximately 7 inches).
4.5 3-in-1 Cutting Modes
- Mulching: For mulching, ensure the grass bagger is removed and the rear discharge door is closed. The dual blades will finely cut and redistribute clippings back into the lawn.
- Posing: Attach the grass bagger as described in Section 3.4. The mower will collect clippings in the 2-bushel bagger. Empty the bagger frequently for optimal performance.
- Bakutkast: For rear discharge, remove the bagger and attach the rear discharge chute (if provided). This mode is suitable for taller grass where mulching or bagging is not desired.
5. Vedlikehold
