Operating Instructions
Follow these steps for correct and effective pet nail grinding:
- Introduce the Grinder: Turn on the grinder (without touching the pet's nails) and allow your pet to get used to the sound and smell. This helps reduce anxiety.
- Select Port and Speed: Choose the suitable grinding port (Small, Medium, or Large) based on your pet's size and nail hardness. Select either low speed (7000 RPM) or high speed (8000 RPM) using the respective buttons.
- Apply the Grinder: Gently touch the pet's nails to the grinding wheel. Hold the grinder at approximately a 45-degree angle. Grind each nail for a short duration (e.g., 5-10 seconds) to avoid overheating the nail and causing discomfort.
- Reward for Every Success: After grinding each nail or paw, reward your pet with their favorite snack. This positive reinforcement builds a connection between nail grinding and a pleasant experience.
- Clean the Grinder: After each use, remove the wheel cover and gently clean the grinding wheel surface with a wet paper towel or cloth to remove nail powder and impurities. This maintains grinding efficiency.

User Tips
- Acclimation is Key: Many pets are sensitive to new sounds and sensations. Allow your pet to sniff and get accustomed to the grinder while it's running before attempting to grind their nails. Positive reinforcement with treats can greatly help this process.
- Suitable for Large Breeds: The ROJECO N30 is designed with an ultra-powerful motor and a 'For Large Pets' grinding port, making it suitable for larger dogs like Labradors, as well as smaller and medium-sized pets.
- Replaceable Grinding Heads: The diamond bit grinding wheel is designed for durability, but like any abrasive, it will wear over time. You can purchase extra diamond grinding wheels to replace them when the grinding effect diminishes.
- Short Sessions: Instead of trying to grind all nails at once, especially for anxious pets, consider doing a few nails at a time over several sessions. This can make the experience less stressful for your pet.
- Visibility with LED: Utilize the dual LED lights to clearly see the nail quick, especially on darker nails, to avoid cutting too deep and causing pain or bleeding.
