Safety Information
Please read all instructions carefully before using the clippers. Keep this manual for future reference.

Operating Instructions
Preparing Your Pet for Grooming

Image: Visual guide to the four preparatory steps for pet grooming: cleaning, combing, trimming knots, and beginning the clipping process.
- Clean the Pet's Hair: Ensure your pet's hair is clean and dry before grooming. This helps the clippers glide smoothly and prevents damage to the blades.
- Comb the Hair: It is advisable to use the provided stainless steel comb to manage the pet's hair as much as possible, removing loose fur and minor tangles.
- Trim Knots: Use the hair-cutting shears to cut off any hair knotting that cannot be combed smoothly. Attempting to clip through severe knots can be painful for your pet and damage the clippers.
- Familiarize Your Pet: Allow your pet to get used to the sound and vibration of the clippers before starting. Turn them on briefly near your pet without touching them.
Grooming Process
- Power On/Off and Speed Adjustment: Press the power button to turn the clippers on. Press it again to cycle through the three available speeds. The current speed (RPM) will be displayed on the LCD screen.
- Adjusting Blade Length: For precise trimming, rotate the fine-tuning knob on the clipper body to select a blade length between 0.8mm and 2.0mm. For longer cuts, attach one of the 6 guide combs.
- Clipping Technique: Hold the clipper firmly and move it in the direction of hair growth. Use smooth, even strokes. Take breaks as needed to prevent the blade from overheating and to keep your pet comfortable.
- Monitor Battery: Keep an eye on the battery percentage displayed on the LCD screen. Recharge when the battery level drops below 25% (charging icon will blink).
Maintenance
Cleaning the Blades
Regular cleaning is essential for optimal performance and longevity of your clippers.
- After each use, turn off the clippers and detach the blade.
- Use the provided cleaning brush to remove any trapped hair from the blade and the clipper head.
- You can rinse the detachable blade under running water, but ensure it is completely dry before reattaching it to the clipper body. Do NOT rinse the main clipper body.
Oiling the Blades
To maintain blade sharpness and reduce friction and heat, apply a few drops of the included clipper oil to the blades before and after each grooming session. The LCD screen will display an oil reminder icon when lubrication is recommended.
Storage
Store the clippers and all accessories in a cool, dry place, away from direct sunlight and moisture. Ensure the clippers are fully charged before long-term storage to preserve battery health.
