6. Operating Instructions
6.1 Pre-Grooming Preparation
Before clipping, ensure your pet's coat is clean, dry, and free of tangles or mats. Brush your pet thoroughly to remove loose hair and knots. This will help the clippers glide smoothly and prevent pulling.
6.2 Turning On/Off and Speed Settings
Press the power button to turn the clippers on. The LCD display will show the current speed setting (Low or High) and battery level. Press the power button again to switch between the two speed settings. The low-speed setting (5000 RPM) is ideal for anxious pets or sensitive areas, while the high-speed setting (7000 RPM) is suitable for thicker coats and less sensitive dogs.

6.3 General Clipping Technique
- Hold the clippers firmly and comfortably in your hand. The ergonomic design assists with maneuverability.
- Always clip in the direction of hair growth for a smoother, more natural finish.
- Use gentle, even strokes. Do not press too hard against the skin.
- For areas with thicker hair, you may need to go over them multiple times or use a lower comb setting first.
- Regularly check the blade for hair buildup and clean as needed to maintain optimal performance.

6.4 Grooming Sensitive Areas
For sensitive areas like paws, face, and around the ears, use the narrow blade attachment (if included or use the clippers without a comb for precision). Always exercise extreme caution and use the low-speed setting. Gently stretch the skin to create a flat surface for clipping.

6.5 Quiet Operation for Pet Comfort
The clippers are designed to operate with low noise (below 50 dB) to minimize stress and fear in pets. Introduce the clippers gradually to your pet, allowing them to get accustomed to the sound and vibration before starting the grooming process.

- Wipe off any excess oil with a soft cloth.
