TROUBLESHOOTING
If your cordless clipper does not seem to be operating or
charging properly, please check the following: Check the
outlet's current by plugging another appliance (one you know is
in proper working condition) into the outlet.
Make sure the unit is not connected to a power source that
turns itself off when lights are turned off.
Make sure the clipper and charging transformer contacts are
clean and free of hair or other contaminants.
Verify that the blade assembly moves freely and is mounted
properly.
The battery is a non-consumer replaceable battery. Return to
Wahl for replacement if and when necessary.
