ATTACHING GUIDE COMBS: The comb attachment is grooved to fit snugly over the blade. Place blade guard over comb, then slide the comb down firmly as far as it will go. Make sure the comb is seated securely against the lower blade. To disengage the comb, pull and slide the comb upward until it is off the clipper.
