To adjust Wahl clipper blades, the user must detach the screws on either side of the blades, and then move the blades by small degrees until they are properly aligned. Over time, Wahl clippers might fall out of alignment, especially when used on thick or coarse hair. Adjusting the blades ensures a safe and accurate trim.
Cleaning the blades prior to adjustment ensures hair does not get caught between or under them. It is also important to allow the blades to cool prior to making any adjustments, especially after long periods of use.
Step 1: Loosen the screws
Some Wahl clippers feature only one screw, while others have two. Loosen the screws just far enough to allow small movements. Most models require a flat-head or Phillips screwdriver, though a coin might work when the proper tool is not available.
Step 2: Shift the top blade
The proper alignment for Wahl clipper blades requires the top blade to sit approximately 0.8 mm offset from the bottom blade. Moving the top blade only will permit more precise adjustments. Holding a thumb or finger on the bottom blade ensures it does not move accidentally.
Step 3: Tighten the screws
Tightening the screws slowly is essential to avoid shifting the blades back out of alignment. Alternating between the left and right screws will ensure even tension between the two sides of the clippers. Afterward, two drops of oil will lubricate the blades for subsequent use.
