The CHI for Pets Small Area Pet Hair Trimmer is perfect for spot trimming on pet paws, face and ears. This convenient and compact pet hair trimmer utilizes an extra small blade for sensitive and hard-to-reach areas on pets. It is small enough and gentle enough for both dogs and cats, as well as for breeds of all types. For short or long-haired pets, as well as thin to thick and curly pet fur, this trimmer is designed to navigate hard-to-reach areas on all pet hair types. No external batteries are required, simply plug in the USB recharging cord between uses. CHI For Dogs provides luxurious grooming formulas and convenient, pet-safe grooming tools designed for optimal care for your dog's coat and skin. Developed with the same superior technologies as in our professional salon CHI human lines, CHI for dogs brings luxury pet grooming solutions to the comfort of your own home. Directions for use: 1. Bathe, dry, and brush your pet prior to trimming for best results. If your pet's fur is matted, consult a professional groomer so as to avoid injury. 2. Before each use, apply a few drops of oil along every few teeth of the blades. Use only manufacturer oil intended for this product. 3. Slide the power switch to the ON position. 4. Position clipper blade flat against pet's body and gently guide along fur. Tilting the blade perpendicular to skin increases risk of injury. Cautions: Product is intended for use on pets only. Never leave a pet unattended on an elevated surface, such as a grooming table. Do not immerse product in water.
