Betjeningsvejledning
1. Kørestilling
- Place one foot firmly on the anti-slip footboard.
- Brug din anden fod til at skubbe fra jorden, så løbehjulet skubber fremad.
- Maintain a balanced posture, keeping your body weight centered over the footboard.
- Periodically switch the pushing foot to reduce fatigue and improve balance.
2. Bremsning
- To slow down or stop, gently and evenly squeeze both brake levers.
- Undgå pludselig, hård opbremsning, især med forbremsen, da dette kan føre til tab af kontrol.
- Practice braking in a safe, open area to get accustomed to the scooter's stopping distance.
3. Adjusting Footboard Height (Two-level rear fork)
The YEDOO Mula Y40 features a two-level rear fork, allowing you to adjust the footboard height for different terrains.
- Nederste position: Ideal for road use, providing a lower center of gravity and easier pushing.
- Higher Position: Suitable for rougher terrain, increasing ground clearance to prevent scraping.
- Consult the scooter's frame near the rear wheel for instructions on how to adjust the fork position. This typically involves repositioning the rear wheel axle in different slots.
