Clipper Maintenance
Your Wahl clipper blades were oiled and aligned before leaving our factory; however, it is possible for blades to get bumped out of alignment. Blades must be realigned if they have been removed for cleaning or replacement.
- If your clipper has a taper lever - position the taper lever in the close cut position.

- End of top blade teeth should be approximately 1/32" (.64mm) back from bottom blade. This is important so that the clipper does not cut too close or allow the moving cutter to touch the skin.


- Extreme left-hand tooth of top blade must be covering or 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.
If blade alignment is incorrect, add a few drops of oil to the blades, turn clipper "ON" for a few moments, turn "OFF" and unplug. Loosen screws slightly and adjust. Tighten screws after blades are aligned.
OIL 
The blades of your new clipper should be oiled every few haircuts. Simply place a few drops of oil on the teeth of the blades. Use only the Wahl oil included in the pack. Due to the high speed of your Wahl clipper, the correct type of oil must be used. Do not use hair oil, grease or any oil mixed with kerosene or any solvent, as the solvent will evaporate and leave the thick oil slowing down the blades. Wahl Clipper Oil is a very thin, natural oil which will not evaporate and will not slow
down the blades.
POWER SCREW (Not found on all models of Wahl Clippers)


If your clipper has a power screw, it has been adjusted for peak efficiency before leaving the factory. However, if voltage in your home is low, you may need to readjust it.
To adjust power, use the plastic brush, a screwdriver or a thin coin to turn power screw in a clockwise direction until the arm strikes the coil, making a noise. Then, slowly turn power screw out (counterclockwise), just until noise stops. This is the maximum power setting.
The cord should not be used to pull the clipper. Since freedom of movement needs to be maintained, care should be used to keep the cord untwisted and unobstructed. When stored, the cord should be coiled and the unit placed in original box or storage pouch.
This clipper has been designed for household use.
TAPER LEVER 

Some Wahl clippers are equipped with an adjustable taper lever. The taper lever is conveniently located near your thumb (if you're right-handed), so it can easily be adjusted while the clipper is in your hand.
The taper lever adds versatility to your clipper by allowing you to gradually change the closeness of your cut without a guide comb. When the lever is in the uppermost position, the blades will give you the closest cut and leave the hair very short. Pushing the lever downward gradually increases the cutting length. In its lowest position, the taper lever will leave the hair approximately the same length as the 1/8" guide comb.
The taper lever will also extend the use of your blades since a different cutting edge is used in each setting. In addition, if extremely heavy haircutting has jammed the blades, it will help you remove hair that has become wedged between the two blades without removing the blades. While the clipper is running, rapidly move the lever from "close cut" to "longer cut" a couple of times. Doing this each time you've finished using your clipper will help keep the blades clear of cut hair. If your clipper stops cutting and this does not help, your cutting blades may be dull. Either replace them or return them to Wahl for sharpening.
