On Clippers with adjustable blades, your Wahl Clipper blades were oiled and aligned before leaving our factory, however it is possible for the blades to get bumped out of alignment. Blades must be realigned if they have been removed for cleaning or replacement.
End of the top blade teeth should be 8mm to 1.6mm back from bottom blade. This is important so that the clipper doesn’t cut too close or allow the moving cutter to touch the skin.
Extreme left hand tooth or top blade must be covering or be to the left of the first small tooth of bottom blade.
Extreme right hand tooth of top blade must be touching the big tooth on the bottom blade.
