3. Setup
3.1 Initial Charge
Before first use, fully charge the clipper. Connect the charger to the clipper and plug it into a standard electrical outlet. A full charge typically takes 3-5 hours. The lithium-ion battery is designed to hold its charge for an extended period.
3.2 Blade Preparation
Prior to each use, apply a few drops of the included blade oil to the blades. This ensures smooth operation and prolongs blade life. Wipe off any excess oil.
3.3 Attaching Guide Combs
Select the desired guide comb based on the coat length you wish to achieve. The kit includes color-coded guide combs for easy identification (1/8", 1/4", 3/8", 1/2"). Align the comb with the clipper blade and snap it securely into place. Ensure it is firmly attached before beginning grooming.

4. Operating Instructions
4.1 Preparing Your Pet
Ensure your pet's coat is clean, dry, and free of tangles or mats. Brushing the coat thoroughly before clipping will help achieve a smoother, more even cut and prevent blade snagging.
4.2 Grooming Technique
- Turn on the clipper using the power switch.
- Hold the clipper firmly and move it in the direction of hair growth (with the grain) for pets. This helps prevent irritation and provides a natural finish.
- Use long, even strokes. Avoid pressing too hard against the skin.
- Regularly clear hair from the blades and guide comb during grooming to maintain cutting efficiency.
- For sensitive areas, exercise extra caution and consider using a longer guide comb or scissors.

5. Maintenance
5.1 Cleaning the Blades
After each use, turn off the clipper and remove the guide comb. Use the provided cleaning brush to remove any trapped hair from the blades. For thorough cleaning, the blades can be detached (refer to the full user guide for specific instructions) and rinsed under water, ensuring they are completely dry before reattaching.
5.2 Oiling the Blades
Regularly oil the blades with the included blade oil. Apply 2-3 drops across the top of the blades and 1 drop on each side of the blade set. Run the clipper for a few seconds to distribute the oil, then wipe off any excess. This lubrication is crucial for maintaining cutting performance and preventing rust.
5.3 Storage
Store the clipper and all accessories in the hard storage case in a cool, dry place. Ensure the blade guard is in place to protect the blades when not in use.
6. Troubleshooting
- Clipper not turning on: Ensure the clipper is fully charged. If it has been stored for a long time, it may require a full charge cycle.
- Blades snagging or pulling hair: This is often due to dull blades, insufficient oiling, or a dirty blade. Clean and oil the blades. Ensure the pet's coat is clean, dry, and detangled. If issues persist, blades may need replacement.
- Clipper getting warm: It is normal for clippers to generate some heat during extended use. Ensure blades are clean and well-oiled. If the clipper becomes excessively hot, turn it off and allow it to cool down before resuming use.
- Excessive noise: Ensure blades are properly aligned and oiled. Loose components can also cause increased noise.
